Understanding Wheel Offset and Backspacing | Jeep Wheels

Buying new wheels for your Jeep can be an exciting feeling. However, There are a few things you need to know before you start. Buying the right wheel the first time can be done with a little research. In this guide we will go over Wheel Offset and Backspacing for Jeep Wranglers.

So, what is wheel offset and backspacing?

They are measurements that determine how far into the wheel well, or farther out, the wheels will sit when installed on your Wrangler.

Wheel Offset is the distance from the centerline of the wheel to the wheel mounting surface, which bolts to your hub assembly on your Jeep. Wheel Offset is Measured in MM and is a determination of how far out your wheel and tire will poke outwards, or in some cases tuck back into the wheel well. Offset is commonly a negative number in those wheels that are made to sit out past the outer fender. 

Wheel Backspacing is the distance from the wheels mounting surface, to the rear, or inside lip of the wheel. It is commonly measured in inches. Wheels with more backspacing will not have as much inside wheel clearance, and will likely rub suspension components, or other obstructions. The less backspacing a wheel has means more room for clearance of these objects, and are also made for lifted jeep's and large tire setups.

Determining the correct wheel backspacing and offset for your tire and wheel package can be a daunting experience. Here are a few tips and tricks to easily get your correct measurements and leave the worries and scientific calculations to the professionals.
