I need help with wheel size!
Alright my TCM xB is coming in this week and for sure I'm gonna get new rims. I want to keep the same size and use the stock tires (im a poor high schooler). The wheels I found I like are R-1 Racing Sports Spec-V Wheels. I'm lookin at the information on it and then I go back to the sticky of the xB wheel size. I dont remember being so confused since Pre-Calc class! Please help me and tell me if this will fit! :? Thanks a ton if someone will help :oops:

Hubcentric rings are a ring that take up the gap betewwn the innermost area on the wheel/rim and the snout of your hub. It makes it so that the load of the vehicle is not resting soley on the wheel studs. This picture should help you out a little.

As for the spacers, yeah, the wheels in question will sit inward a bit farther than you'd probably like. It shouldn't harm anything, it just won't look as good as if they were closer to the fender lip.

They will fit ok. They are going to sit approximately ½" further out than the stock steel wheels with the wheel covers. You'll also lose about ½" of clearance on the inside, but it should still clear everything ok. They will still be about ¾" from being flush with the fender in the front, and probably about 1½" from being flush with the fender in the rear. From the info you listed, you will need to get hubcentric center rings that have an outer diameter of 73.1mm and an inner diameter of 54.1mm. Also, your post did not show anything about the PCD (bolt pattern). Make sure that this is 4×100 if you want it to fit a Scion xA/xB. If they could get you this wheel in a 20 offset instead of the 40 offset, it'd be ideal.
