So last week my tpms came and I went to a local gas station to check all the air pressures.

One of the tire was really low on air so I filled it back up to 34 psi.

Today, a week later, the light came on again and I went to a shop to get the tires checked for nails or any holes and they said there were none and just tightened the valves more.

I did upgrade my front tires from 225-40-19 to 245-35-19

and I'm running stock rear tires 245-40-19.

I've been running this setup for about a month and never had a problem with the tpms or anything until now...

Could this be the problem?

 

I would say most likely but not sure. They were set for ur original stock tires so the change might throw em off. I switched from stock to aftermarket Work Wheels n my tpms is always on.

 

did you try doing the reset procedure?

 

Try resetting your ECU, it worked for me!!!
