Hello, I have a Silver 2007 FX4. I just put on a 2" Day Star leveling kit. I have no clue what size tire to go with. I want to go as big as possible with a 18" KMC 798 ADDICT Black with out rubbin. Can i go with a 325/65/18 or 325/60/18 or do I have to go with a 305/60/18? I am lookin at the Nitto A/T Grapplers. Please help anything. or would it just be better to go with a 20" rim and tire 33"x12.50X20s????

 

Yes, you will have to stick with 33's. Wheel diameter does not matter.

 

i have heard people on here go with 325s what the differece??

 

I suggested you go with 33's. 325/60-18's are approximately a 33x13.00-18 tire. A 305/60-18 is basically a 33x12.50-18 tire. Both should fit.
