sorry if this question comes up all the time, I want to know the absolute largest tire size OD and width I can safely run a a 2006 F150 4x4 with 17 inch rims! currently Im running 265/70/r17 no problems at all! would like to get wider and taller,any info would be appricated

 

Does the truck have a leveling kit on it or stock?

 

With a leveling kit you can fit a 35x12.50 with minor rubbing by using the OEM wheels.. Anything smaller will fit fine.

 

no leveling kit whatsoever,trying to keep it as stock as possible,fyi, Im probably gonna run bfg all terrs from your company

 

I'd suggest their 285/70-17 (33x11.50) then.
