If you want to know what size spare tire cover you need for your 2008 Jeep Wrangler JK check out this helpful chart from Jeep Daily. Then you can take a look at some of the more popular spare tire covers in this post.

1. The first thing you want to do is look at your spare tire’s size on the sidewall of the tire. It will look something like 255/70R18. Don’t worry about what those numbers mean right now, but a simple thing to know is the last number is your wheel size in inches. In this case, you have an 18-inch wheel.

2. The second thing you need to do is look at the handy chart we have built and locate your tire size in this chart. We have built this chart based on stock tire sizes that came with the Jeep Wrangler. If you have aftermarket rims and tires you might need to do your own measurements.
