Hey all, I'm looking to purchase a set of 15 inch aftermarket wheels for my GS. The factory Rally wheels sit pretty tucked in on the front. They're 15x7 with 4.00 inch backspacing. I'm thinking of doing a 15x7 with 3.75 inch backspacing to bring it out a bit in the front. I have 245/60/15 tires in the front. Also looking at putting a 15x8 in the rear with 4.50 inch backspacing and 255/60/15 tires. Any ideas/input/or other advice?
You can easily run that tire size in the back. The 15 X 7 Buick wheels have 4 3/8" back spacing. http://www.v8buick.com/index.php?threads/official-guide-to-rally-wheels-chart.196455/ I would leave that back spacing as is if I was you. 15 X 8" is fine with 4 1/2" back spacing. Read up. All this has been discussed many times. http://www.v8buick.com/index.php?threads/what-tire-size-and-rim-combo-are-you-running.194022/
