I have a 2006 quad cab 4x4. Looking to put top gunz 2" front leveling kit on it. What is the biggest size tires I can put on my 20" stock rims. I have been looking at Nitto terra grapplers. I currently have 275/60/20'S on itThanks Chief

 

check my post. FINALLY

 

what is the size of a 305 tire i have 285 and those dont look all that much bigger than my tire and i think mine is 33" i hear you have to level if you put a 35" on and isnt that 315 but those are some nice tires and tell me how you like the nitto's thinking of getting a set my self

 

A 305/50/20 is a 32 inch tire. Since the stock 20s come with 33 inch tires, you're actually filling less fenderwell than the stock tire did.

I wouldn't mind a leveling kit but it won't serve any useful purpose. I won't gain any ground clearance, I don't need any tire clearance, and I'd run the risk of bottoming out the stock shocks.

Right now my mod money goes toward a torque converter. Oh, and some fender flares since the wider tires throw crap up the side of the truck.
