TPMS question

[scott71law]

Hi all I just had wheels put on the car and when I did the relearn procedure for the pressure monitors everything seemed to work fine but now the pressures are all in the 40’s on the dash- the tires were inflated to 34 when I had them mounted. I’m hoping I didn’t get bad sensors, they came as a set of four (and were not cheap) but it seems odd all four tires are 43-44 psi according to these monitors now.

The procedure is pretty straight forward hard to screw it up but is there some other trick to this I might have missed lol?

I got the tool and with key on engine off pointed it at the valve stems on each tire in the order it listed in the owners manual and the horn went off for each one as it was supposed to and beeped twice when I was done. Tire pressure warning was off when I started it again but the pressures were reading way higher.

Thanks for any info.

I solved this issue, the tires actually were aired up to 43-44 for some reason at the shop. I bought a gauge and verified them and then went and lowered them to where I want them.

Cool. I was gonna ask if you checked them yourself with a gauge. I run mine at 36 cold. I check them twice a month, regardless if I drive it or not. I keep a gauge in my console all the time. Someone at your shop wasn't paying attention!!

Yeah it's surprising because they are usually awesome to work with, never any issues. I have to look at the tire to verify but the door sticker indicates 35 cold PSI for this car, I don't know what the range on the actual tire indicates yet. I've never had a car in the 40's but I run my suburban at 50 psi lol.


Another thing is these tires are slightly shorter than the stock tires (these are 245/50-18 instead of the stock 245/55-18) but I can't see why that would make them put more air in them. I did grab a digital gauge to keep in the car now.

Awesome! Yeah most tires for our Camaro's usually have a max PSI of 44, not to exceed..
