Valvestem Size
Hello everyone!
We just ordered a 2024 Montana Legacy 3231 CK with IS suspension.
I'm looking for the valvestem diameter base. So i can order GM TST replacment to be installed. My TV is a 2024 AT4 3500. Please can someone help?
Thanks Mike

Unfortunately I do not have your answer. I was more curious that your Legacy edition didn’t come with the tire pressure kit. My 2022 3791RD Legacy had them as “standard” equipment.

My interpretation is that the OP is wanting the GM gear installed so that his in-dash display will show the fiver's tire pressure instead of utilizing the separate TST display.

Yes Lee-Ci is correct. My Montana has the Legacy edition and has IS and disk breaks. Sorry my first time of trying to ask.
I think at one time there was a thread about this ?. I think the Diag was .425 or .624

Roadkill, i researched this a few months back. Nichols Machine and Welding in Phoenix area can supply GM sensors in the .625 valve stem diameter. About $48 per wheel. My TV is a 2020 GMC, and that year TV could not read pressures above 100 PSI without replacing a TPMS receiver (and flashing). I’ve heard but not verified the newer GMC’s will read something like 150 PSI now. I was going to be Appx $300-450 into just getting my 2020 TV to read above 100 PSI, so I went with TST system. I’m going to try and paste a link to Nichols, but if it doesn’t work just search for Nichols Machine & Welding.
