Wheel and Tire Size

Alright guys, I'm fielding a lot of calls about wheel and tire combinations that work with our systems. Here's the elevator version:

In order to run 37" tires, you need to use to the stock wheel size (8" wide with a 6.25" backspacing) and you'll need our control arms and full leaf pack.


There are exceptions to this, but that's our official answer. You can stretch the backspacing to 5.75" but that depends on your tire.

We're all running 37's on stock wheels with our control arms and leaf packs without issues. My truck has Walker Evan's beadlocks with 37" Toyo Projects, with a 5" backspace and I had to install glass fenders in the front to clear the tires. If you don't mind losing a little paint, you can run 37's in the rear with the add-a-pack, but it's going to rub the front of the rear fender well. With stock arms and 37" tires, you're going to rub back of the front fender well.

When you get away from stock wheel width and backspacing, you're going to have to stick to 35's or get arms and full leafs with reasonable backspacing.
