BOLT PATTERN 101: How to Measure Wheels for Perfect Fitment

Показать описание

Wheel bolt pattern can be tricky so always measure before you lay down some cash for a set of wheels at a swap meet. For 4, 6 and 8 lug wheels it’s simple. Center of one stud to the center of the one across from it. For 5 lug you measure from the outer edge of one stud to the center of the stud across from it.

In our case, we ended up with a bolt circle measurement 4.75 inches. This is commonly known as 5 on 4 and 3/4. This is a small GM pattern, used on most passenger cars from 1949 until the 1990’s. Here’s a quick guide:

5x4.75 = Small GM bolt pattern

5x4.50 = Small Ford bolt Pattern

5x4.50 = Large Mopar bolt pattern

5x4.00 = Small Mopar bolt pattern

5x5.00 = Large GM bolt pattern (Chevy trucks and ‘70s full size cars)

5x5.50 = Large Ford bolt pattern

I'm looking for a set of 14" rims with a 5x5.5 bolt pattern. I can't find any anywhere.

i thought measuring of bolt pattern called out for center to centor of bolts?

If the factory bolt pattern is 5x114.3 is it safe that the aftermarket pattern is 5x114 ?

I have the same lug pocket? My mag stock lugs have the 60° end, which sat in the stock rim .these have the slightest play on the hole. Is there a solution out there?

From the outside edge of one to the center of the other one is 5 and 3/4 not 4

The center is still important it should support weight of vehicle. Studs are ment to keep wheel against mounting flange, not weight of vehicle.
