Can any one help what is the max tire size I can put on a 2004 F150 XLT Reg Cab 4x4 with out a lift kit. Thinking about the Nitto Terra Grappler.. The tire size now is 235/75/17

thanks

 

I saw someone here running 285/65-18's which are a 33x11.50-18. So, you should be able to run a 285/70-17 (33x11.50). I've also seen people running 305/70-17 (34x12.50) with the stock rims with only a 2.5 inch Daystar leveling kit.

 

My stock tires are 275/65R18's...what is the largest tire size that will fit my truck without lifting it at all?
