Tire/Wheel switch

benny12 · November 29, 2021

I am in need of new tires and am not really liking the 20" polished wheels that came on my 2017 LTZ. I have located a set of brand new take offs from a 2021 AT4 with Goodyear Wranglers. Questions:

1. Is there any way to get the tire pressure sensors from the 21 to work with my 17?

2. If the answer above is no, is it worth putting the 2017 sensors in the new wheels? I am concerned about lifespan, will they last another 60k miles?

3. If it makes sense to switch the TPMS sensors over, can I break the bead on the AT4 Wheels and switch the sensor? Has anyone done this without rebalancing?

The answer is no, the sensors don't work.

You can either swap your sensors or just buy 4 new ones. Most sensors last 7+ years in my experience so I guess it's up to you.

And yes, you can break the bead using a tire machine and push the tire down far enough to swap the sensors. It will not require any rebalancing.

Just an FYI, I had a 2018 and bought a new 2021 AT4. My winter tire rims would not fit on the front of the 2021, they hit the brake caliper. The bolt pattern was the same. I'm not sure how the 21 rims would look on a 2017, might be fine going the opposite of what I did.

1 - No. Frequencies are different. New trucks are 433mHz, old are 315mHz.

2- If they are original to the truck, I'd just get new ones for your new wheels. $40 each on the Chevrolet Accessories website and if you act fast, they have some good discounts going.

3 - IF they would work (which they won't) no need to re-balance as you'd be just changing one sensor for another.

Keep in mind the tire size has changed as well. If they are AT4 18 inch wheels, they are 275/65R18 which is a 32 inch tire, a smidge larger diameter than the stock 275/55R20 that came on your truck. Speedo would read .5mph slower than actual speed.

If they are AT4 20 inch wheels, your speedo will be off a bit further, 2mph slower than you are actually going. The AT4 20"s use 275/60R20 which are a 33 inch tire.

Yea going 2019+up new body on an older truck there is no fitment issues. Old to new there is due to the 4 piston calipers up front.

Not to hijack but T1XX wheels look pretty good on the 14-19 trucks IMO. I have Chevrolet Accessories 18" ZR2 style wheels from the T1XX catalog on mine.

Thanks for confirming my current plans, I am hoping it works out. The financials should work out- comparable tires at the nearby Les Schwab are $1400 mount/balance/fees/tax/etc where this should be about $1k minus whatever I can sell my 20's and the 21 sensors for.

My 17 is Graphite Metallic, so my plan is to the spray paint the polished part of the wheels black for a black on dark gray/blue/black/green look that the graphite metallic has. If I like it I will strip the paint and get them powder coated or live with the black spray paint. These are 265/65 18 so I will be going down slightly, less than 1% per the tire size calculator I used.

Again, I appreciate the forum's help, there is a great knowledge base here.

If my 2022 3500 is ever built and delivered I might want to get a set of rims to install snow/mud tires for camping. What are the better sources for aftermarket rims? I am looking for function not fancy.

Stay healthy

For function not fancy, just go to Craigslist. I'm in Denver, there are a ton of wheels and wheel tire combos available. I am convinced it is from oilfield trucks, or more so guys with money and trucks.

I made the switch this weekend. The only real PITA was switching over the sensors. You need a size 10 torx to disconnect the sensor from the valve stem. My 1/4 drive torx socket set didn't go small enough, and all I had was a folding deal with 10 sizes in it. I ended up cutting off the no. 10, but broke it when bending it into the shape of an allen wrench. I grabbed the now 1" long piece with vise grips and went to town on removing and reinstalling sensors 3/8 of a turn at a time while sitting on a 2x4 to push the sidewall down. Also have a magnet handy because those screws end up in the tire inevitably. Also, have a bigger magnet available for when the magnet ends up in the tire.

Thanks for the answer. Just looked and found some nearby (<100 miles). One had it all...tires, rims and pressure sensor. Will try again after the truck is built and is at least on the way to the dealer.
