Whats the biggest tires i can fit on a stock ram 1500 4x4? I need new tires and want to get bigger tires than the 31s on it now

 

Could be wrong, I think leveled you can fit 33's????

 

The stock tires that come on 20s are 33". You can go a little wider than stock, but not much. Leveled you can go to a 35, width being limited again.

 

33.4x11

 

I have the 2" Bilstein leveling shocks, and it clears a 285/70/17 easy (33"x11.5") on my stock wheels. I am pretty sure you can clear a 35 if you run aftermarket wheels that kick the tire out a bit from the frame and upper control arm. If you run a 35 on the stock wheels it will rub on the upper arms for sure, and most likely on the frame/fenderwells when you turn.

 

Do you need spacers for the a level with 35's. Or will they only rub at full lock?

 

Mine is a 2006 1500 4x4. I'm running 33x13.50x20 Mickey Thompson ATZ's on 20x10 rims... no lift, no rubbing.
