88 GT Wheel Fitment

Is there a FAQ anywhere on fitment data?

I have a set of 17x9 20mm offset Cobra R Wheels to put on my car. I need to know my tire options, it seems as though there is great controversy. The car has KYB Shocks, and Ford Racing C Springs. I dont' want to have any issues with rubbing.

255/40/17 ? 245/45/17? 275/40/17?

Thanks for all the help!

I had R's on my 88 with 245/45's up front and had no rubbing other than at full lock. The remedy? I just didn't turn as sharp anymore. I had 255/55/17's in the rear and had to roll the fender lip, educate the inner fender with a BFH and flipped the quads. I did the same on the 89(275/40's all around). The 80 LX(exact same rims/tires that were on the 88) required more attention to the front fender since I relocated the K member forward 3/4" so I had to roll the fender in front of the tire as it made contact only when turning.
