I'm not sure the argent center is available. It was added here with PaintShop. Guess I'll go back to the webpage to see.
Call Wheel Vintiques. I know they don't list a 17" Buick Ralley but I'd wager to guess that they could cut out your center and put 'em in 17" hoops. We used to have a guy here who could change the backspace on any stock wheel by moving the centers. He retired, too bad. Also, A GS has plenty of room in the back for 285/40/17's. 255's look to skinny IMO. I run the 285's on my Turbo Regal no problem with the Grey centered Torq-Thrust 2's. I had 'em bolted on my GS for a kick and even though the backspace was only 4.25 on a 9.5 wheel they cleared. Looked bad**s. I actually thought about 17X11's with 315/35/17's for my GS to fill the fenders. My 15x10 Welds with MT 28/12.5/15 have a 13.4 cross section and they fit with very minor fender lip trimming. The 315's are only 12.7 at the sidewall. Should fit nicely with a 6" backspace.
Only problem I can see with that (I looked into it a few years back) is that you end up with the smaller center into a larger wheel so you have all the extra chrome on the outer part and it looks kinda odd... Steel is heavy too...I think if I were to upgrade in size, they would have to be aluminum... later Tim
Salt Flat I prefer the Salt Flat! It's why i'm selling my Cragar Street Star, i ' m going to fit 8x17 and 9,5x17 with the grey (painted) center...like the ones sold by A.R.. With the Burnished Copper paint and the good stance, i think i will love my Skylark even more... Ohhh, i think i'm getting pro-touringed.. :Brow:
