The bolt pattern of your car is a vital consideration while you are going out to get replica wheels for your vehicle. Now, what is the bolt pattern of a car? Well, bolt patterns can also be called lug spacing & it implies distance in between imaginary circles made in between lugs on car wheels. It’s indicated with figures presented as 4×4.25. In this case the 1st number represents 4 lugs on a car wheel while the following digit notes between lugs located at opposite direction to one another in the said circle.
The post here is a little bit on how to measure the bolt patterns of a car wheel which is followed by a brief on bolt patterns for various cars.
Generally, cars have around four, six & eight lugs on wheels- sometimes the number could be five or seven, especially in case of US passenger vehicles. While you have to measure wheels with even-numbered lugs such as four lugs, you just need to gauge distance right from center of hole to center of hole straight across it. Hence, here you would need center-to-center gauge. On the contrary, the odd numbered lugs say five lugs would call for a more elaborate measurement. Generally you would gauge it by calculating distance between back of hole to center point of other hole across & then multiply the measurement by 1.05.
In regards to bolt pattern, you should understand the notion of BCD or “Bolt Circle Diameter”. Lay a wheel on ground & create a circle passing through center of every lug hole on the wheel- this is your BCD & you are just left to calculate diameter of the said circle.
The simplest route to gauge BCD is through bolt-pattern gauge. Take the car wheel off & use your tape to gauge lug studs located on your car’s rotor. In case you are confused on whether your BCD comes in millimeters or inches, it is best to get a measuring tape with both the scales. Run your tap from center of 1 stud to center of stud lying across the car wheel from first- 4/5 bolt wheel implies 2nd stud over and six-bolt wheel signifies 3rd stud over.
If you know your car wheel BCD simply add on the bolts. Thus, if the BCD shows 4.5” & you have got five lug studs, then bolt pattern would be 5 by 4.5”. In case you have got four bolts on 100mm BCD, it is 4 by 100mm.
