Centerbore?

[pdub18]

Hey guys what's up...

Why don't any rim companies put the centerbore of their rims on their sites along with the other stats?

I'm looking at the TE37 Volks but I have a centerbore of 57.1

I have no clue what the Volks have.

Also, what exactly is hubcentric?
I just haven't heard of the term, although I probably know what it is, since I've been fixing up my car in Germany and have gotten used to German terms.

If you have hubcentric rims, do you still use regular lugnuts?

I know my stock rims had little green centering rings that went around the hub.

Hub centric simply means the mounting hole in the back of the wheel is the same inside diameter as the nose of the axle. That centers the wheel on the hub when you torque the lugnuts up. It can either be machined to the exact diameter or use a centering ring system. Both are hub-centric.

I wish that the wheel companies would do a much better job of posting their rim specifications, it is VERY frustrating. I have skipped over several brands specifically because they did not even list offsets on the corporate web page, let alone centerbore or weight info. You might find that Google can be helpful, though.

The Volks should be fine, I think they are 64mm or larger (don't quote me though). You will need centering rings (the hubcentric rings) to match to your car. Make sure you specify this when you buy the rims!!!

To kind of restate what Luke said, hub-centric rims are centered via the center hole in the rim matching the raised circle on the axle hub, or by adding a ring that acts like a round shim to match the rim to the hub (the part with the wheel studs in it). The wheel studs only keep the wheel from falling off. This results in a perfect fit. This is opposed to lug-centric rims, which use the wheel studs to center the rim, as well as hold the rim on the car. Tire rack has a very informative tech section on their website, you might check it out.

If you don't center the rim, you could have problems, including possibly a vibration in the tire, despite it being perfectly ballanced.

Thanks guy!:-)

I really hope the Volks will fit my centerbore.

I'll send them an e-mail.

Again..thanks for the help :-)

If i was you, hope that they are bigger than the 57.1 and thats the same hub size i have on my cavy... my rims are 73mm bore... Call the manufacturer and they'll give it to you, but ask to talk to a tech, i got the wrong # the first time around.
