Its about 60 right now in cali where i live and I didn't drive yesterday night or today at all, I turned on my car and the sensor went on. I freaked out and measured the pressure the right side seemed to be 31-30 and the left 29-28 on my stock tires 20inch r/t with r&t. I did have my right front tire replaced about a week ago, but never have seen this light so im guessing that tire still has sensor and its just the cold making my tires go low? Max psi is 44 but 32 is recommended on placard. Should I just wait till tomorrow to check it out or what? Any help wanted.
