Moto Metal 958's 18"x9" biggest tire.........
 

I have an 06 XLT 4X4 Reg/ cab flairside stock suspension. What's the biggest Nitto Terra Grappler I can put on with no rub. Would consider a leverer in the front if it makes a diff.
Thanks

Several members have fit 325/60-18's (33x13.00) on 18x9 with only a leveling kit. Whether you have any rubbing or have to trim anything will depend on the backspacing of the wheel. If it's 5 inches or more you should be fine.
