When I started out on the off-road scene, I realized that I had a lot to learn about four-wheel-drive tires and how to determine what size to buy for my truck. I spent a lot of time researching the tires and rims before I bought anything. Since it was so hard to learn how to measure properly, especially for the backspacing, I decided to create a site that consolidates all of the information I learned. My hope is that the information here will help other starting four-wheel-drive enthusiasts to choose their tires and rims for that first suspension lift installation.
