TPM Question

[Gary]

I just went and fetched a set of factory rims and tires from a fella from his 2004 GMC truck, my Yukon needs new tires. But the Yukon has the TPM system and I'm unsure if the new set of rims and tires I just got has the TPM, is there any way to tell just by looking without cracking the tire off the rim to know?

If not I can just have these new tires put on my rims but heck if it's already got the sensors I just need to go have them tested for balance and put 'em on and save the mounting charges.

Thanks for any help Oh the tires and rims I got from him are identical to mine. Identical, same tire, same rim just more tread!

You could put one on and give it a try. If it doesn't have the sensors your car will complain. If it does have them it will work.

I would take a look at your valve stems, see if there is anything that looks different about what is visible. The systems that Discount tire installs have a block on the stem that you can see. If there is something that you can see different from the normal valve stem, then compare that to the other set.

a GM tpm valve stem has a nut that holds it to rim from outside look at yours if its the same not a rubber black old style your golden unless its broke inside

Btw, if the wheels you bought have sensors, they will have to be learned to your vehicle. They will not automatically read.
