I have a 2009 Unlimited X and I'm going to be getting my 33's next week. I have the stock wheels and tires on right now. When I get my new wheels and have the sensors reinstalled in the new wheels and run the 33's at 28 psi will it trip the light on the dash? If so, how to you reset it for the bigger tires and the new psi?

Thanks in advance.

 

The PSI information for stock wheel is on the B pilar.

Now if you want to change the threshold of the TPMS computer information you need a device such as the AEV ProCal, this device allows you to change the PSI value that will light up the TPMS dash light.

 

Yep, dealer can reset it, but do yourself a favor and get the ProCal.

Better yet, don't have the sensors moved to the new wheels and just use the ProCal to turn the system off

Those wheel sensors are easy to break, and expensive to replace...

 

Yes, I just did this Friday. New (to me) wheels and tires. Used the Procal to recalibrate speed sensor for larger tires and then turned off the TPMS by setting it to 0. Took less than 3 minutes.
