i'm looking into buying these wheels
http://www.enkei.com/Performance%20specs/RZ-5.html

and was wondering if the 18x19.5 would stick out in the rear, and i wanted 18x8.5 or 7.5 in the front.

what does each part of like 225/55/16 mean? i know the last number is the wheel size, waht are the other two numbers?

also waht is the offset stand for? and what's the offset for the stock rims on a tc

 

19.5 may be a lil to wide.....

 

I wouldnt do any thing wider than 9" wide in the rear...but are you ready for the bad news?.......They wont fit your lug pattern. These are only available in 5x114 like the new xB. In fact these are the "TRD" wheels available at the dealer for the new xB.

 

oh... dammit. what's the lug pattern for tc's then?

 

tC is 5x100. also this may help your pther questions
