Well I need some help. I would like to install the new pro comp xtreme 33's on a factory wheel. I contacted Pro Comp and they list that 325 60 18's(33X12.5x18) will fit on 8in wide wheels.(they Advised that the 7.5 in stock wheels will be OK). I swear that I have seen some trucks on here with Nittos (same size) on a factory fx4 rims, however I can't seem to find the pics. Is anyone running a similar setup and if so does it rub, or fit at all? I plan to install a 2in front end leveling kit prior to mounting the tires. Your input will be much appreciated.

 

Yeah, I've seen some members running that size. They will fit with a leveling kit. I'm sure someone will post a pic soon.

 

I looked at some today actually. Use the search funtion and type: 325/60/18.
