Where can I find out the center bore measurements of my tire? Websites I look at don't seem to get that specific on the wheels? Any suggestions?

 

A ruler?

 

lol I thought that to but someone told me that it is a very detailed measurement like down to .01 or .001. Im trying to get hubcentric spacers made.

 

look in the sticky wheel faq ;)
Bolt Pattern
4x100

Center Bore
54.1mm

Nut Size

See the wheel fitment sticky post

its 54.1 mm

 

If you aren't sure of your measurements, you can take your wheels to a tire shop, and they can measure for you. You can even test out some Hub Centric rings to be sure they fit....

 

That gives me some ideas. Thanks

 

54.1mm is for stock. Im assuming its larger since i have aftermarket wheels.

 

If you are getting the spacers made locally, just take a wheel to the machinist. Accurate measurement can only be made with a short vernier caliper.

But most wheel manufacturers list what the wheel is bored out to, what wheel is it?

 

Helo Diamond wheel. 18x7.5

 

I couldn't find much info about those online. I emailed a company that sells those wheels and they replied with a 72.62mm cb. Either way, I would check the actual wheel before using that spec.
