4wd Tyre Pressures - How Low Can You GO!?
Вставка
- Опубліковано 14 сер 2024
- 4x4's and tyre pressure go hand in hand, but how low can you drop your tyre pressure when 4wding off-road before breaking a tyre bead?
In this video we find out, we go out in the 4x4 into the Lancelin Sand Dunes and keep dropping the tyre pressure until we have a failure.
We also show you how to break and reseat a bead, if you do happen to break one while your out on the track.

Very informative and practical video. I like the way you're so cheerful all the time. Great work. Thanks!
I just found you this weekend and binged all your vids, great stuff man. Greeting from Germany :)
You’ll need therapy
I saw another great method to reseal the bead using a ratchet strap around the perimeter in the middle of the tire which flexes the rubber outward to the rim while inflating. Worked a treat
I have used the rachet strap method in the past Jack, I find the deodorant trick is much easier and gives you more consistent results 🙂
Well you've change my way of thinking, didn't think you could go that low. Thanks for educating an old guy, always good information.
FYI from the states, I have used starter fluid for getting a tire bead to reset. spray some up the outside of the tire when you are ready to light it . Flame will run down to the inside of the tire with no finger or lighter in it. (Big Truck Driver)
Just learned something today. Great information. Excellent video. I normally drive 40-45 miles on the beach to go fishing at no man land (PINS). This knowledge is valuable. Many thanks again.
When trying to reseat the bead, spray fluid for no more than two seconds onto the inside of the tire, then create a half-moon on the rim, then a trail off the tire, and light it from the tail. This way you won't be directly over the tire when the 'explosion' occurs.
Another tip is to remove the valve stem as to let the air (exhaust) to be naturally released after the reseat method is done.
As like baa baa black sheep, 1 Bar for sand 2 Bar for rocks and 3 Bar for tar.
I do love your video's Obviously the most important thing to have when 4 WDing is a sense of humour!
slowboat 3 bar is way to high for tar in most cars
I would not use 2bar for sharp rock I use 2 bar for pavement and 1 bar for everything else but sand dunes .6-.7bar
I've got factory 17" wheels on my GU patrol with 265/70 mud tyres and usually 15psi works great. But drop to 10psi when it's really soft and have never broken or even got sand in a bead. But yeah... 18-20" wheels probably aren't a great idea offroad. The difference between 15 and 10psi is incredible. Got to love lancelin too!
This should be playing on a loop at Inskip Point somehow.
Well done, great video. 👍
Hahah so true Ben, you always know your going to have a good laugh when you watch Inskip videos 😂
First... Love ur work man
Your tests are always done right and a great watch
Still my favorite 4x4 tips video ever. This video has helped me soo much in just a stock sr5 Tacoma with 265/75/16s. I can confidentiality get almost anywhere and I don't damage the trails at all. Best 4x4 tip imo.
Edit: Running 3-5 psi on stock wheels in snow never popped a bead and travel at 20mph easy
Excellent information
Just remember that anything under 20psi drop speed right down, say 15-20km max, and at 8-10psi even slower
Hi Michael. Very informative video, thanks for sharing.
Would you consider making stickers of your logo to sell? Maybe 5"X5" or something like that? I really like it, and would definitely buy a few. Thanks.
I learned about lowering tire pressure from another video, had no idea it was a thing. Now that I hear it from an Australian, I am believed. Love the videos
Yeah with all our soft sand beaches here it's super common and well known here - the tyres are just wider. Put a cup on the sand and stand on it, the cup sinks with your weight. Put a plate on the sand and stand on it - it handles your weight easily. I heard recently on a tech podcast (ATP) from someone in the US who is learning to drive on sand regularly and he didn't know about lower tyre pressures being good either. It's interesting.
Possibly the most useful UA-cam video I've ever watched. Thanks lads. I have to run 17s due to brake caliper size, but good to know that with a decent tyre (BFG or dueler maybe) I can go very low. Time to acquire a compressor.
Also makes me even more impressed with my old Forester, which recently got me up a big dune fully loaded with camping gear with me thinking I'd gone low enough by dropping from 40psi to 25...
Thank you for doing this experiment. Looks tedious but well appreciated
My usual setup is 10 psi front 8 psi back. Rarely I’ll go to 8 front and 6 at the back. That’s for tall desert dunes climbing.
For low dunes, between the dunes, and beach 24-12 depending on the sand and what I’m doing/how long staying.
Another great video.
Just thought I’d add that passenger car tyres don’t have the same sidewall strength as typical LT/off-road tyres. LT tyres can run all day on the beach at 12psi, but a passenger tyre could overheat and seperate if driven for too long at the same pressure.
Keep up the great videos!
@Mickmike Mick 11:07
Something people might not know is the Australian Standards for tyres has a condition that tyres stay on the bead even when flat, so flat tyres at highway speed are somewhat safe. They will come off of at some point, but they stay on pretty well especially in sand.
Yea I've had a completely flat rear 20" 245/30 tyre and it drove at 60km/hr for 15km no problems (well it felt like it wanted to fishtail somewhat).. stuffed the inside of the tyre wall and the rim got buckled but I got home. 🤣
Im surprised the tyre didnt come off.
WOW! Lynx & tyre inflation. I'd never have thought of that. great vid. Thanks
Thank you, mate. It's amazing test on the beach sand. I much appriciate it.
Good day!
“Like a glove!” Much respect for the Jim Carrey reference. 👌
Or, “like a finger in the bum”
yellow vest on yellow sand...hmm safe?? That was a great demo Michael - thanks mate - very useful!
no yellow sand up at lancelin
Awesome test guys! I won't be stressed about 13psi anymore 👍👍👍
Another great video Michael, love the work you have put into demonstrating how low you can go. I would be swearing and cursing if I had to change a wheel dunes 🤬🤬🤬😂😂😂.
This was a great video for resetting a tire bead in the field.
11psi at lancelin blew the air out the bead . A few kicks and the Kings twin compressor sorted her right out in a jiffy. Nonetheless , bad advice mate. Most people aren't going around in circles on almost flat terrain. Hit a dune with momentum with sub 14 psi and high risk bead will flex for enough time to let air out.
Totally agree. There's a reason why companies like Michelin produce three sets of pressures relating to tyre loads and speeds for their off-road tyres (e.g. Michelin XZL and XS). Unless you have specific information to the contrary, from either the vehicle or, preferably, the tyre manufacturer, as a rule of thumb:
On road and rocks - use normal road pressure.
Tracks and sand - use 80% of normal road pressure. Max. speed 65 km/h (40 mph).
Emergency soft - use 60% of normal road pressure. Max. speed 20 km/h (12 mph).
I know this video is a bit of fun, but people will see this and drop their pressures to 0.4 bar (6 psi) and drive around like lunatics, and wonder why, if they're lucky enough not to pop a bead, why their tyres have failed spectacularly a few thousand km's or miles down the road! Tyre damage is often hidden inside the structure where you can't see it at these pressures.
Great programs and really appreciate the down to earth ideas and wonderful camaraderie you have with you travel buddies.. Well done!
Once again you have produced a great informative fun video that anyone can follow. Really enjoy your content. Keep up the good work.
Back in the day, when I was much younger and much sillier, I managed to pop a bead on the Spectron in that same area. No idea what pressure I was running because, who cared about actually measuring it? It was just a case of, if it looks soft enough off we go.. Things have certainly changed since then :) Great clip and good advice about getting the tyre back on the bead quickly.
Went to 12psi on Calcup Hill in a stock standard 200series with factory 18" rims and rubber. Worked an absolute treat, i actually think highway tyres work better in sand, just my opinion, thoughts?
Great way to quickly reseat a bead, dangerous but quick. I prefer the ratchet strap method, if you have the right equipment.
Yes, the smoother the tire the better they are on sand. We used to use tyres from Mirage jets on our buggies (30 years ago). They were just big balloons that ran at 10 PSI on widened 15" VW rims. We used to get them for 5 bucks each too. 18" rims are not really ideal for the job due to their lack of wall. They are OK for day-tripping with your mates, but a set of 16" with ATs is much more versatile. I tow a camper trailer on the beach and run my 16" ATs at 15 psi on my LWB Pajero, which is fine for most chopped up beaches. I carry all the necessary recovery gear, but because I've been driving on the beach since I was 15 (40 odd years ago) and the only time I've had to use my gear is to help others who do not have the experience. It always amazes me how many people do not let down their tyres at all and get bogged as soon as the sand gets soft.
Yeah absolutely mate, out here in Saudi Arabia everyone runs highway terrain tires off road and they work wonderfully but of course with the smallest rim possible to get the biggest contact patch when deflated. If you go back like 10 years ago absolutely no one ran all terrain tires let alone MTs only in the past couple of years they became more popular because of the looks. The absolute best tire for sand is what we call baloon tires, they're bias ply and super soft sidewall so they can really spread out when deflated. They're very tall but also quite narrow kinda like a tractor tire. You can find them like the Maxxis desert master but they're usually only sold in the gulf region.
Well done guys...often wondered where the limit was
Great tips! And you guys are having way too much fun!
LOVE the shirt!! I can't wait to order a decal and matching shirt. 😍
High lift jacks are great for breaking the bead.
Another good vid mate. 👍
Intresting test!
My advise is to try and inflate the tire with just the compressor first.
Less dangerous.
This.
No way you'd need to blow a bead on with a tyre that size on that wheel.
Would've seated using the compressor easily.
I do to 285/55/10 - 16 to 14 psi and drive like a boss in a ford ranger. Thanks for the video mate.
My front passenger tire popped off the bead at 10 PSI in the dunes today doing donuts in 4wd. They are 33'' General Grabber ATX 285/75/16 on a toyota tacoma. I think for a street tire it may be okay but with something that has a larger sidewall you will run into more trouble.
this is one of the best and Very informative and practical videos I have ever seen in my life bro . I like the way you're so cheerful all the time. Great work.i have shared your video in my facebook page Thank you very much and keep up.
That's rad dude...Good info...So glad you have a blue shirt on...Something different...😎👍...
Pretty much a pretty much good video, pretty much.......
Bloody good video mate, like all of them. Miss the good old Tuesday uploads
To pop the tire off the rim, I just put the tire on the front and turn sharp as I pull forward until it unseats.
nice test only thing ive got to chip about this is when corning with reduced tyer pressure is to do your turns gently
had an au falcon ute with an open diff on loose sand at 12psi with absolutely no issues, standard highway 205/60/16 LT tyres
was shitting bricks as i was by myself, only had a pair of maxitracks for recovery
Great video good to know how to put the Tire back on
4lb in each type was my lowest ever, worked 100%, only had to move the Pajero 20ft, then pumped them all back up to 20lb...
Man I love your stuff, well done and thanks so much for spending your time driving around, getting bogged and carrying water 😝 keep it coming!
Super Great Video Mates! Very Informative and fun.
Another great vid Michael, well done mate.
@10:05 "If you got any soap..." Obviously, we don't! Surely it is overkill to bring soap when you already have Lynx, gotta think about weight saving 😁
Good vid. mate, I've learned a lot by watching your channel. Thanks very much - Peter V.
Everyone of your videos are so informative. Thank you
Awesome vid
Had my fj at 3psi got me unstuck then back to 10 for the rest of the day, my rule of thumb for my fj is 18psi rocks, 15psi mud, 10psi sand,
Really excellent video, I had previously not thought that I need to be able to reseat a bean in the outback (because I carry a spare tie)
Super funny and instructive videos mate! Cheers from Buenos Aires, Argentina.
Nice one micheal well done.😎👍
Good work boys !!!!.
Great work. I always wanted to know this info for my 4x4.
Hey mate, need to go for a 4wd down south and grab one of those shirts off ya! Love the channel, keep it up
If you dont want to get stuck at all on the sand then go straight to 10psi.. sometimes there is extremely soft sections on beaches that even 10psi will struggle to get thru but it will get you thru.. dont be lazy let your tyres down before you hit the sand. You dont want to get bogged then have to let your tyres down cause then as you let air out the whole car will get lower to the ground and belly out on the sand then you have to dig the sand out from wherever its touching the diff or chassis
Love your videos, very new to the game and learning so much from each video, love the fact you show the wrong way (and why you don't to it ) and the right way. Glad you have a blue BT50, same as mine lol
Suggestion for your next video...
Bring some Sheila's...
Great videos.. very informative...
Lancelin dunes and wedge dunes you can usually get away with 15psi to get around 😁 I always run that and have never had a problem 👌🏼
fantastic channel guys
Great video, very informative as always.. need to do one on the car itself, am thinking to buy that model.. thanks..
what damage have you done to the side walls.
This the best info vid for tyre pressure questions thank you
Thanks for the comment Rod 🙂
Awesome video, thanks!
Good video 👍👍 Thanks for sharing 👍👍
Great video. Great content.
Great video! 🤙🏾🤙🏾
I thought that if you went 4 Wheel driving you had to have big chunky, noisy treads and jack up your suspension high enough to see over the dunes....no?....oh, and bolt on those tyres!.....oops, I forgot the 50 ft aerial and some grungy crap music blaring out. Don’t forget the high lift jack strapped onto your roo bar and the naff plastic board things to help you dig yourself out of sand!
I don’t rekn you’d be the first person to wreck a few cones out in those dunes...
Nice vid mate, when I hit the sand in the GU it’s straight to 15psi all round, never had an issue
Pretty sure this guy smashes a few cones every morning.
@@mini696 😂😂😂😂😂
What a great video Michael, informative as always
Great stuff!
Great video mate,,,, I've been watching all your other one's as well, I like your style of fun yet informative videos.
Question! how low can you deflate your tyres that have tubes fitted? Like my lumbering 4X4 truck?
Cheer's Mate, Steve.
I don't know exactly how itd work but you'd have to be careful due to the fact the tyre may spin on the tube pinching it and bursting it. Not sure if car tyres are the same but have done it on a bike once
Great video mate!
I drop to 10psi in sand straight up
I have 20 inch rim with 30 inch tires. Will get 18 inch rims later. It looks good without a crazy bulge at 17-18
FANTASTIC video.
Thank you.
I Learnt a LOT, a LOT.
Thank you.
A great bit of info. Very informative!
Great video. Really informative. Thanks mate
Great video. Have you done a video on how to navigate a beach that has been chopped to heck. Had a situation where i needed max trax to get going after stopping but then needed to stop to grab the trax. Didn't help i was in a Subaru forester with about as much torque as a wet sock hanging on a cloths line.
A great video.
Definitely helped to answer some questions.
It also depends on the size of your tyre and the weight of your vehicle. Some tyre brands also seat better than others
9:05 - I'm going to make that my message tone.
Omg I missed that first watch.
As usual, a great video!
Awesome video matey. Thank you
what kind of load did you have on the truck? were you fully loaded for a trip? and how much does your vehicle weigh?
Mike. I'd love for you to do a review on a throttle modifier. Need an unbiased review.
Got the stockies on the back now do some skidsss
I am observant when I’m driving and I see so many people driving with a tire really low PSI and not even knowing about it. People seem to never check their tires they just jump in their car and drive
A long time ago when dinosaurs roamed the earth, I had a VW Baja Bug that had off road skinny front tires and HUGE sand tires on the back. The back tires only had 5 pounds of air in them. Anything more would cause the care to ride like a rock.
I have run as low as 4 PSI and been fine. You just have to drive with a little bit of sense.
On Morton Island I ran to 10PSI worked great
Great test guys, I get so frustrated with crew not letting their tyres down, nice educational vid.
The lighter getting caught in the bead was such a good warning to those watching, always good when accidental errors educate with out injury 👍
What was the camera and mount that you used for looking at the tyre please?
@Collie Yak It looks like a GoPro Suction Cup Mount and I assume an adaptor for what looks a Sony action cam.
Jon Lloyd cheers
Very informative. Thank you.
I drop my to 15 to 12 psi on sand 31 on 15'' rims no problems yet.
