Tire pressure light wont turn off
So I recently swapped out my stock 2012 JK Wrangler tires for the Rubicons BFGoodrich mud tires and rims and now my tire pressure light will not turn off. Any suggestions? Also, with these new tires I have noticed my speedometer is roughly 3mph over the displayed speed at 30mph and at 60mph its 5mph over. Is there a possible home fix I could to correct this, or should I take it into a shop to have it readjusted?
