DOES MY 07 MAGNUM SXT AWD HAVE TIRE SENSORS
TIRE COMPANY TELLING ME I HAVE TPMS SENSORS, DO I?
AND WANT TO PLUS SIZE TIRES AND RIMS TO 20" WILL I NEED TO UPGRADE
BRAKES AS WELL?
HOW WILL 245/45-20 FILL UP THE WHEEL WELL, LIKE STOCK 18" OR A LITTLE
According to Edmunds it does. Have TPMS that is.
Stock brakes will work fine with larger wheels. Transfer the TPMS sensors to the new rims. Magnum will take up to 30" diameter and 8" wide. (255/55-R18 for instance) Keep the tire inside those dimensions and you should be okay. You can easily compare tire sizes on TireRack.com or similar tire sites.
