I recently put 20x9 American outlaws on my 4th gen 1500 and I'm getting a 2 inch leveling kit and I was wondering if anyone can tell me what's the tallest and widest tire I can get without rubbing. People have been telling me 35's will fit and others are saying 34's won't come close to fitting. I need some help guys

 

I also have a 2" leveling kit and 20 x 9" wheels and my 35's fit beautifully with no rubbing. I have a 2014 1500 4x4. You should be ok.

 

You're a life saver. What's the width or them?

 

My tire size is 35"x12.5R20

 

And no rubbing what so ever?

 

Not at all, been running this set up for over a year now.

 

Alright man, thanks! What kind of tires?

 

I have Cooper STT, they are a Mud Tire.

 

i have seen a few people on here and other places have the air bags in the rear and i was wondering what the benefit/ function of the rear airbag is?

 

I use them for when I tow my trailer, it weighs 8,000 lbs fully loaded so it really makes the rear of my truck squat down. With the air bags it levels the load and really makes a difference in handling when towing. The kit only cost $75 on Amazon and took me and my Dad about an hour to install.
