I installed this on my 38' Reflection TT. Works great. I did this myself by hooking up truck to trailer and removed one tire at a time. I then used the power tongue jack from trailer to break the bead of tire from the rim. It gave me enough room to install the sensor and it work great!
Thanks for a thorough review. I agree with you. Your key complaint about being able to manage the screen real estate, specifically, what indicators & apps to show where is a key challenge for auto/truck manufactures. To date, most manufacturers are failing at this challenge. While default "views" should always be selectable, the driver should be able to drag the rendering of apps between the main display, the side display, and/or the HUD. Consider what all of us do every day with Linux, IoS / Apple, Windows, and Android devices. The concept is has been well established. It is time for the automakers to wake up LET THE DRIVER DECIDE how they want to use they vehicles !!! Thanks again for a very informative video.
I just bought a 2024 Silverado 2500 HD LT. Trailering pkg. I'm so glad I stumbled upon your videos. Have a 2022 Rockwood 2608bs with TPMS. I'm going to see if I can eliminate having an additional screen on my dashboard following your lead. Thank you for educating us!
Thanks for this video! I just set these up on my 2024 Silverado HD and Imagine and while I haven't used them yet, I have the same gripe. With how customizable the left and right gauge center screens are, I'd love a trailer tire monitoring option to go inside the right side display. I have my transmission temperature in there now as that's the next-best thing I can think of to monitor when towing my RV out west here in the hills.
oh man does this video bring back some memories...i was the dummy who found these in my glovebox after purchasing my new truck and figured hey ill put these in the aftermarket wheels and save the money little did i know they were only for trailers and will not tell you pressure being used on your actual truck wheels lol. Nice video though!
Great video, I just got my sensors installed today went back to the trailer but couldn't get them to pair with my 2024 Denali HD. Had the trailer 7 pin connected and the screen had all the same prompts but one thing now I notice is that I never got that first chip that you noted when the pairing procedure started. One other note my truck was not "running" just in the on position, maybe that was an issue, I'll need to retry
Perhaps. I know they can be very picky about all the parameters being just right in order to pair. Some have mentioned the distance is sensitive too...my trailer is pretty short. But, I did pair with the tires in bed as you probably noticed already. Hope you can get success on it.
Great video! Just got my trailer TPMS setup today on a 2024 GMC 2500 Denali. Went pretty flawlessly. One question…how did you get the sensors to show up on that side portion of the infotainment?
On mine it showed up on the right panel...sometimes I have to swipe up/down if it's on clock or another screen. But only in the Google infotainment mode. If I go to android auto then it disappears. It's my understanding AppleCar play still allows that right panel to show up...just can't confirm firsthand. Hope you get it working.
Great Video!! I just received the camera from GM to mount on the back of the RV and I’m contemplating doing that installation on my 31’ TT in the next few weeks and then the tire pressure monitoring will be next. Have you reached out to GM or have any idea if they’re going to do a software update to move the tire pressure monitoring to the driver screen?
Thank you for the comment! No word yet on software update. I might be in the minority there, but I did learn that if you have Apple Carplay (instead of Android Auto) then my understanding is that right 1/3 still shows up for the tire trailer TPMS. It's a minor detail, but I still like the integration regardless.
@@AdventureRocks I use apple car play all the time so when I do this, I'll let you know how it display's. I'm contemplating a new RV (existing 31' is 23 years old 🙂), so trying to decide if I do both the TPMS/Camera now on an RV we may keep less than a year and then have to relocate, or wait and do on the (hopefully soon) new one. Thanks for your time and efforts on this!
Did you simulate a tire going down in pressure? How long does it take to warn of a blow out? Hopefully the alert is before tire carcass shreds or causes trailer damage.
I only tested once just after the setup/pairing. I didn't time it, but seems like it updated within 5-10 seconds. I could be mistaken, but I think the sensors give less frequent updates when pressure is constant, but then if it changes suddenly the sensors given an update pretty quick...all to prolong battery life I would imagine...that seems to be the behavior I've observed so far. Anyway, I've been very pleased with mine. Some others have reported range issues where longer trailers with greater distance to axles cause connecitivity issues.
I use my Google maps via Android Auto. GMs built-in nav is nearly the same thing being Google powered, but it does require a data connection to be fully operational, which of course is an extra monthly fee via OnStar unless you use your phone as hotspot to provide WiFi to truck. All that to say using Google maps via Android Auto and your phone is simpler and more up to date with traffic and routes. 16:13 vs 16:50 is a good comparision between the two.
@@AdventureRocks Thanks for the response, I would like to have the option to input my trailers dimensions and have whatever map I'm using pick a route avoiding low bridges etc. Google maps doesn't have that capability right?
@@jbyrne9073 Good point. No, I don't believe Google maps supports that feature yet. Most of my travels are in SE where we don't have as many of those low bridges, but I'm with you especially if you have a fifth wheel that is taller.
I have a 2024 gmc 3500. I ordered 4 gm tpms for our 5th wheel and the diameter of the valve stem was not big enough for the rv rims. Their cold temp psi is 110 psi. Any suggestions of what and where to purchase sensors that will work with my gmc monitoring system? Tia.
I hear you. It's my understanding GM doesn't support the 110 psi yet...only up to 100-105psi. I think with TPMS install kits that have extra gaskets there is a way to physically get them to fit/seal, but it can be tricky. I had similar problem on my last 5th wheel with the RAM TPMS sensors and the tire tech had to use a special kit with gaskets and such to make it seal (RAM support the 110 psi btw). Sorry for the bad news there. Seems like GM could fix with a software update.
Just bought those sensors for my 2024 Chevy 2024 3500. The sensor diameter is to small for my camper rims. Do you know if Chevy makes a attachment to fix this?
Great question. Short answer is I'm not sure. Long answer...on my last truck/trailer the tire tech had an issue getting TPMS to seal on inside profile. I'm not sure if it was the overall diameter or what, but the tech had to use what he called a "TPMS install kit" that I assume had a bunch of fittings and washers to help adapt it. He said it was pretty common and something a tire shop should have on hand when I asked. This go round, the GM ones fit with no issues for me. Sorry I cannot be of more help on this one. Hope you're able to figure it out though.
If you haven't found the answer yet, Nichols makes the item you need if you're running something like the 17.5" wheels. With that said, they don't have enough range on longer trailers. Our 40' Cedar Creek wont pair (sometimes I can get one wheel on the front axle to pair but never the rest). Worked great on my shorter trailer though. Nichols: nicholsmanufacturingandweldingservices.com/shop/ols/products/gm-valve-stem-for-tpms-sensor-rim-hole-size-625
Loved them on my 35' Cougar but they dont pair on our 40' Cedar Creek. Shame because it wasn't easy with the 17.5" wheels that need the modified stems from Nichols.
Just curious, if you had them off and at tire store; presuming you used the truck to take them in; why not have them all setup there using the setup tool? I’m pulling a cargo trailer/camper mod and just wish there were some cap tpms sensors to add on. Otherwise may end up going the route you did.
I wish the trucks of any brand had that easy ability to put in the pressure YOU want the system to recognize as the target pressure for the weight of how the truck is being used rather then try and find someone willing to go into the system to change the psi alarm numbers.
@@AdventureRocks Yes, and in talking to friends or family that have tried to get their truck reprogrammed by a dealer or another shop that does mechanical and tires, no one is cooperative in wanting to change the parameters and I sense its because of possible liability reasons. Its completely insane, all vehicles before the invention of the TPMS one puts the air that is required into the tire for the purpose at hand ( having a tire chart and real time axle weights to work off of ) and now dealers or even tire shops will put the air pressure in the tires that the door jamb lists and not even listen to the customer who knows they drive the vehicle almost empty. Logic has become a rare commodity these days, perhaps I am the odd one out but it boggles my mind !
@@charlesb4267 I borrowed an Autel programmer from a friend to do this on my truck. I set the TPMS desired pressure to 45 PSI all around since the truck rides much better that way when not towing, and the weight is bang on with the Michelin specs for the tires on my truck. I run 50 front, 45 rear when not towing. 55 all around when towing my travel trailer.
@@uwskier Well thats a good friend to have, those units don't come cheap that can get into all the settings to modify them and I believe they have yearly subscriptions as well which the average joe would not get enough use out of it. But then knowing how to run the darned thing, I assume there is a struggle to do that unless one has used such tools before. So good on you to have the where with all to tailor your truck for your needs, skipping past the bs created these days.
I have a 2021 GMC Denali XL and pulling a 25 ft Airstream International. They pair up and show on the screen but only work about 30 miles and loose connection. I have had 2 different sets of internal sensors and they do the same thing. The current set is the gm part number. Is there a booster of some sort to help? I have an aftermarket Tire Minder with screw on monitors that have a intermediate booster and it works pretty good. Any thoughts or boosters you know of? The dealership is not much help. Thanks
Sorry to hear. Sounds like a few others are having distance/range issues where the sensors aren't picking up well. You probably noticed my RV is pretty short so the distance is less. One commenter chimed in that there is a GM booster out there, but personally I have not been able to find any part number or further info on it when researching that topic. It seems like all the other aftermarket systems have boosters, so in theory if one could match up the same frequency of the TPMS sensors to an aftermarket version...maybe that could reproduce the frequency? Sorry I'm not more help on this one. You'll have to report back if you learn more.
Thanks. I have heard of others looking but no definite, Other boosters should work but nothing definite. My Tire Minder booster doesn't work with it. It's not overly far but I don't know if the aluminum build of the Airstream makes a difference. Thanks for your help
@@timsmiththesmiths8106 Wow 23' sounds a little short. I know on my last RAM and 44' fifth wheel I measured 28' from rear axle of truck to rear trailer tire and it worked flawlessly. I wonder if other factors like propane tanks or metal objects significantly reduce it.
@@AdventureRocks that’s possible, I do know that GM does not make a booster/repeater for this system so I just decided against it, which is a shame but not going to spend the money for install then not have it work
