Hello everyone. I have a 1999 F-150 Supercab 4x4 and I would like to fill up some of the wheelwell. I have the standard P235/70R16 tires on the truck now and I want to know how large a tire I can put on without having to have any other adjustments made? I want the speedo and ect. to remain as they are.
Any help will be appreciated. Thanks. Maseoo

 

Hey welcome to the board! Any change in the diameter is going to effect your speedometer as well as your overall performance. You can put a new speedo gear pretty cheap though. Mine's only off a few MPH's with these 265/75/16's
