Hi All,
I just purchased a 2012 F150 Platinum. The previous owner just installed new Nexen Roadian At Pro’s. They look great. My question is, the size of the new tires are 305/55R20, which is larger than the OEM tires.
Does anyone know what PSI I should put? Should I go by the Ford’s spec on the door? Also, is there a way to have the speedometer corrected?
Thank you
