What is the biggest tire size that will fit on a 2003 F-150 4x4 without rubbing? 32x10.50?
It is not the FX4 model if that matters. ANd rim size is not important, I will be getting new rims too.
Thanks

 

285/75R16 same as 285/70R17 (33x11.5")

You can fit 305s with wider rims though.

 

I'd suggest running a 305/70-16 (33x12.50) on a 16x10 inch wheel with 4 1/2 inches of backspacing. To fit this combo, you will have to crank up the torsion bars and trim a little plastic off the front bumper's lower valance. In my opinion, this is the best looking combo on a stock height 4x4.

 

i would go the 305's x70 16 ,rims are 16x10 welds these are goodyear all terr and thier is vary little trimming on front lower valance i have had same wheel and tire size since 99 no problems M.W.https://www.f150online.com/galleries...5510:thumbsup:
