maximum tire size

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!

The last truck i had was a stock 91 150 and i had some stock ford rims off of a 92 (new body style) with 31x10.5-15 and i had no problem with fender or bumper rubbing but did have problems when i turned the wheel all the way that it would hit the radius arm but that wasnt that big of a deal . a buddy of mine had a 88 with 285s on a 16 in rim with a 4in backspacing that had no suspension enhancements and he ended up cutting a good amount out of the bumper and a little out of the fender (though im not sure if that was needed) and he had some problems with the tire hitting the radius arm. soo i guess it depends on how much backspacing your rims have and how much cutting you want to do

From what I have seen 32 11.50 15 is the largest that a 4x4 of our trucks can handle with out rubbing bad. I have them on my 2wd with small lift and they do not rub at all.
