so today while i was driving on the highay, i thought id use the tire pressure monitoring system to check my pressures. one wheel read "Rxxx PSI"..does anybody know what this means? thanks in advance

 

i had the same problem after i put on a new set of rims. try to reprograme it if you have the magnet.or take it to the dealer it'll cost you about $35 to $80.or it could be a bad sensor and to change it will cost you about $200.unless you get it used on ebay.

 

I would just ignore it and just buy a $1 tire pressure gauge
