Default Help! cracked wheel repairable? how to figure offsets of used wheels?

FIGURED OUT THE OFFSETS! :0)

Thanks for any help...

I have a set of 18" Racing Hart M5 wheels, I have no idea what offsets they are. They came on a supra I bought a while back and I changed out the wheels, never got around to selling them. But before I do, I am trying to figure out the offsets... They fit the supra perfectly. Also, one of the wheels has a crack (probably from a pot hole) on the inner portion of the rim, so the lip isn't the damaged portion. I pulled them off right when I got the car and didn't notice any issues driving, only to find the crack after removing the tires... Is this repairable? How much do you think it would cost? I am wondering if I should just sell as is, or get them fixed and then sell them...

they are:
18x8.5
18x10

here are some pics.

It should tell you the offset on the inside of the spokes on the reverse side.

Cathy - try to find a local machine shop or welder - let them take a look at it, and they should be able to tell you if it's safe to weld and reuse.

I'd take it to a local wheel repair shop and have them take a close look at it. A crack like that probably means the rest of the wheel took a pretty good shot. A good wheel shop that knows what it's doing will spin the wheel up and have a dial indicator set up to measure run-out. Depending on the results, that wheel may or may not be repairable.

One thing is sure: a wheel failure at speed can result in a big accident; potentially taking out the entire car. Don't skimp on the assessment or pawn this off on some unsuspecting buyer who doesn't know any better!

Thanks for the info. I would never do that! I have a good reputation on here, and on top of that integrity. I would never do such... which is why I am obtaining info before trying to even consider selling the wheels.
