Question about TMPS
 

dear All

This is my first time question about. I really glad to see you all.

Anybody changed the tire from RFT to regular tires?

I did it in local dealer (not Lexus) but it was fine for 500 miles but after that "check tire system" light on. I checked all the pressures but it was all 40 psi. is it too high?

I havn't check the TPMS whether lexus OEM or not. May it cause problem?

:confused:
