To determine the bolt pattern of your car, you can use various online tools such as the Bolt Pattern Finder on TireSize.com, the Tire Bolt Pattern Guide on 1010TIRES.COM, the Bolt-pattern.com website, or the Bolt Patterns tool on BoltPatternSearch.com. These tools allow you to select your cars year, make, model, and option from drop-down menus to find the bolt patterns for your vehicle.

To measure 4, 6, or 8 lug bolt patterns, you can use a device to measure from the center of one lug to the center of the lug directly across from it. This will give you the diameter of the circle in which the bolt pattern resides. On 5 and 7 lug patterns, there are not two lugs across from each other to measure to. The closest way to get a measurement without a bolt pattern tool is to measure from the center of one lug to the outer edge of the lug farthest from it.

It is important to note that not all vehicles with the same make and model will have the same bolt pattern, as different years, trims, or option packages may have different bolt patterns.
