To measure a tire rim’s hole pattern, first locate the holes. For a 4-lug wheel, measure the distance from the center of one hole to the center of the hole directly opposite. For a 6-lug wheel, apply the same method. For an 8-lug wheel, measure center to center across two opposite holes to get the correct pattern.
Begin your measurement by placing the rim on a flat surface. Use a measuring tape or caliper for accuracy. First, count the bolt holes. Next, measure the distance from the center of one hole to the center of the hole directly across from it. This distance represents the bolt circle diameter, crucial for compatibility with your vehicle.
Ensure you measure accurately to avoid fitting issues. If your rim has an uneven number of holes, measure from the center of any hole to the center of the opposite hole to find the diameter.
Once you have your tire rims hole pattern, you can confidently select compatible tires. Understanding these dimensions leads you to assess other critical attributes like rim width and offset for optimal performance.
