There are a few ways to tell if your rims are 5x114.3. One way is to measure the distance between the bolt holes. If they're exactly 5 inches apart, then you have a 5x114.3 rim. Another way is to look at the markings on the rim itself. If it says 5x114.3 or PCD 5x114.3, then you have a 5x114.3 rim. Finally, you can check with the manufacturer of your vehicle to see what size rims it takes.
