Wheel Fitment Guide

Thanks for posting a link to my website axld86!
The combo I have is 18x8 and 19x10 forgeline GA3 wheels. Backspacing is something that is specific to your car. For example, I am using a Moser 9" axle made for the G-body, it may sit differently than the Gm 7.5 or 8.5 rear axle in relation to the frame rails. Another thing to keep in mind: these cars were welded by hand and variations can exist. The differences may not be much, but something like 1/8th inch can cause huge clearance issues when you put your wheels on. I could not fit 5" backspacing on my driver side rear, but I could on the passenger side... so I went just a bit shallower that 5" backspacing. Lastly, keep in mind if you go with a 10" wide rim, its actually 11" wide including the lip of the wheel (or at least some manufactures have it that way)... so you will probably end up rolling the fender lip. (which I have not covered on my website yet...
When putting your wheels on its best you get your own measurements before ordering/buying them if you want the max contact patch.

The answer is NO. I mocked them up, and they might work with at least a 1/2" of spacer action. They hit the rear of the UCA and the tie rod end pushes into the rim at full right lock.

225/65/14 would look good IMO.
Have you considered 225/70/14 on all four to fill in a little more? Theres a lot of room down there for that 14"tire to fill.
Seems to be a pretty popular size for those running 14" wheels with stock suspension.
Ive seen 245/65/14 on the rears before and thought it looked pretty good too.
Kanek with a 7 inch wheel and a 3.75 backspace you can pretty much fit any 14" sized passenger car tire on the market. Since most 14 inch wheels are 6 inches wide most tire companies stop at a 225 wheel; as that is maximum recommended width by the manufacturers. The widest tire that I know made for a 14 inch rim is the bf Goofrich radial T/A 245/60/14.
