Ok i put on some 18" wheels..And you know the tire light thing that tells if its low..

the light came on so i checked it and all my tires had 32..so i reset it and the next day it came back on checked it again still had the same pressure..So i put 34 and reset the the light...A couple of hours later it came back on

can somebody tell me whats going on..

thanks

 

if you have 07&up tC, the pressure sensors are in your stock tires... so when you take the tires off, the sensors are gone too.

but if you have 05, 06 tC, the sensors are part of abs, so you shouldnt have a problem even if you take the tires off.
sometimes sensors just freak out from aftermarket tires... idk why

 

ok thanks

and yea its an 05 and didnt have the sensors in the tires

 

Try a 'hard reset' of the tire sensor button. It's in the manual.
