Put new 20" wheels on the car today, with new TPMS sensors. After a few miles of driving, the car recognized that there were new wheels and asked if they were 19" or 21". Being that these tires are much bigger than the 19"s, I opted for the 21" option. It successfully communicated and accepted the new sensors. Now the car is telling me that I am low on pressure on 3 of the 4 tires. I have a staggered set-up. 245/40's up front, 275/35's out back. Can someone who has 20"'s on their car please enlighten me how to get the TPMS to stop freaking out? What pressures are you running or what pressures is the TPMS looking for? Many thanks in advance.
