You can find so many channels with smooth talk on ACC and then you have Aris, where he overflows knowledge to all of us. Thanks Aris, I keep learning from you, every video.
This is fascinating to watch and very eye-opening. It's impressive how many details ACC simulates and how those tiny details have an impact on your driving. Thank you very much Aris!
Hi Aris, It's so impressive what you're doing in the game and how it all works. Could you also make a video of how it works with the rain tires? I just don't get it to the right temperature, no matter how many psi I put in there. Thank you very much for this game
Your tyres will get hot by braking and accelerating. You get less temperature as it rains because of the external temperature and because you won't go that hard on the pedals. previous to a hotlap, do a lap with a lot of braking and accelerating. A common myth is that going right and left will take the tyres to temperature (because w've seen in on TV). No. It will only "clean" the tyres from small objects sticking to them.
paul ricard is a weird track for pressures especially so i made myself a cute motec panel for temps that has core temps and pressures, plus temperature histograms that makes understanding what goes on a lot easier than line graphs. :)
ive seen this myself at monza the 2 righthanders onto the back straight always .2 up left side of the car. makes the car harder to nicely get through the chicane. i need to watch so many more of these never would have even thought of half of the things youve put into the game the more i watch these the more you just shake your head and think wow..
Very interesting info about physics, thanks for the video! I'm wondering do pilots in real life also do this micro-management of tyre pressure? Sweet spot of tyre pressures seems to have very small range
Thanks! Have you heard of the drivers complaining during the races how the car "doesn't work" or the tyres have "no grip"? Then a bit afterwards managing to pull a fast lap again? More than marketing talk and complaining is actually the tyres and car going out and in again their operational window. I'm pretty sure you have experienced it too in ACC during a long 1 hour stint. The car seems good at start, slower at some points, good again and so on. Modern racecars and tyres are very sensitive indeed.
@@ArisDrives For the average guy to really see this demonstrated in real life motorsports start watching some Nascar races as the pit reporting the teams will tell the reporter that they will make the car adjustments on pitstops most of the time just using air pressure and only major adjustments which exceed the adjustments capable with tire pressures are mechanical adjustments to the suspension. One thing Nascar does do really well is involve the fans with broadcasting in car team communications and knowledgeable pit road reporters getting actual in race short interviews with the teams crew chiefs.
I'm doing a league race this weekend on Spa, tire pressure changes a lot on that track and my rear left and front right were so far off from the rest, what a freaking headache to tune but I finally got them all around 27.6-7 within each other now.
Do a couple of tenths of PSI really change the tyre radius enough to change the rotation of the wheel? Wouldn't you get more of a handling change just because the pressure is further away from optimal and the available grip is less?
In a word, YES. Good quality racing tire pressure gauges have tenths on them for a reason. I guarantee you that real world competitive teams ALWAYS treat their tire pressures this seriously. It is the ONLY mechanical contact with the racing surface. In fact, I would be willing to bet many teams have a tire specialist, whose job it is to do nothing but measure, match and maintain tires. It really is that important and that technical and that precise. When I worked on a Top Fuel dragster team for 10 years, every tire was measured for circumference at specific pressures, and this info was recorded for every tire. You could literally tune the launch and speed just by changing to a larger or smaller diameter tire, although each tire, (hand made by GoodYear) was supposed to be identical. When the tire truck showed up at the track, teams would be standing waiting to start sorting through the tires to get specific diameters they wanted. 2 tenths of an inch diameter could mean the difference between launching straight or veering right, and that's on a narrow wheelbase dragster, not a wide-body GT car.
How should we take into account the time progression during the race? If you can manage to use a set of tyres during a 2 stint period they will be subjected to very different atmospheric and tarmac conditions during those 2 hours.
Very clear. But I would like to ask if the same is true for front tyres. How is car behaviour when approaching or exiting a corner with different front pressures? Ty
Rear fine tuning is more important because of course the cars are RWD. Also the cars turn with front tyres so you can adjust your steering input to point the car. You can't directly control the rear movement except with the pedals. I tend to do so for all 4 tyres, it makes my results easier to understand.
What about tempratures? While we focused on the pressures temps between tires may not be evenly distributed right? Should we aim for optimum temps around tires more than pressures or vice versa?
Depends on the tyre type, manufacturer etc. Pirelli GT3 tyres we are simulating are made specifically with client racing and drivers level, so they are extremely "good" for a wide range of temperature, and the pressure becomes the most important factor of performance. Other tyres have much more narrow temperature range of operation so you need to work with both of them to make it work properly.
Hi sometimes i see that wheel psi also depends on the hour in the game so asphalt temp is not same and because of this a saved setup can be different depending on hour. It this true?
Absolutely. The tyre heat depends on the brakes usage and duct openings, the ambient temperature, the track temperature (night? clouds? sunny?), the driving style, the tyre wear etc etc. Every single one of the above causes, influence the heat generation and heat changes the pressure. So you cannot set the pressures in one condition and then simply use the same ones in different conditions, even if it's only a cloud covering the sun or the sun is lower in the horizon.

Not enough people watch these.
Its all very interesting and stuff that most would never think of.
Excellent info. I didn’t realize it was so sensitive to the small changes in degrees.
Spot on totally understand whats happening with the tyres and very helpful to pick a corner where you will need the best exit to make time 👍
Excellent info, thank you. I'm just starting out with ACC with much to learn. It's the little things that can make a big difference. G'day from Oz...!
Glad it was helpful!
My tyres are always Under Pressure - they always Want to Break Free. Next thing I know I'm sliding off the track and Another One Bites the Dust.
Sounds like you are a Queen.
omfg, I had no clue that was a thing. "You still have much to learn, Padawan."
Thank you for that.
This is fascinating to watch and very eye-opening. It's impressive how many details ACC simulates and how those tiny details have an impact on your driving. Thank you very much Aris!
great info to be better or solve a problem on specific turns
Amazing lesson! I’ve never pressured my tyres extremely carefully. Now I’ll check that they are all equal to the .1 👍
Thank you so much. Penny drops aplenty. You are the man 🍻

Sure thing! But first I want to fine tune some problems present in the rain tyres heat generation and characteristics.

Great explanation.... can you do a tutorial about how to set the temp taking into account the air temperatura? 🌞
This is very helpful will have to give this a try thankyou

You sound like charles leclerc race engineer 😂 I'm just waiting for you to say "understood we are looking, slow button on"
Its amazing to see your videos and learn even more, Thank you Aris =D
Never even considered this! 😲
Very well explained thanks!
just brutal the physics tyre model, amazing
Thank You!

Inside knowledge into dev hacks. Sweet ;)
Any news on fixing the t500 ps4 ffb issue? Gettin frustrated here.

When can console have seat adjustments settings back?
I just want to see the bonnet of the m6 😅
Just get the PC version, you’ll thank me later ;)

@@ArisDrives Thanks a lot. So i think it will be usefull to have in mind track/air temp when saving/creating setups.
Bravo.
I did something like this a month ago with plans from Woodglut.
