I have an '88 F150 4x4. It is stock height and I really don't plan to lift it.

I am currently running 265/75/16 (32x10.50) tires on 16x8 rims with no issues but when I get new tires I want to go bigger. I do all of my business with Discount Tire and they say that I can run 285/75/16 (33x11.50) with no problems.

I have seen it posted that the '88 - 91 trucks could run 33x12.50's with few or no rubbing issues. I am considering going to 305/70/16 (33x12).

Tell me what you guys think!

 

80-86 fit 33x12.5 no problem
87-91 may have to shim out the front bumper
92-96 most always have to shim out the front bumper.

Here is my 84 with Pro Comp A/T 33x12.5 and stock height

You can shim it or you can just cut what bit of clearance you need form the inside of the bumper.
