Going with the Shelby Razor wheels 20 x 9(6"back spacing)........would like to put 275/35-20 out back. Someone stated they stick out some from the fender. I do not want the tire pass the fender....but would also like to go as wide as possible.
It's not the tire that sticks out past the fender it's the rim depending on offset. The 275 is 10.8" wideso there will be an extremely small amount of sidewall bulge in a 35 series sidewall.
I have CS67 20x10 wheels (+45mm offset and 7.26 inch backspace) with 275/35 tires and I am at least 0.5 inch inside the fender edge. The wheel you are asking about has a rim that sits 0.56 inches deeper from the fender than my wheel (assuming that the Razor has a +24mm offset and 6.0 inch backspace). Just make sure the tire you get is designed for a 9" rim and you will be fine.
depends on teh rim offset at stated...I also have 275-35's on s 20x10 out back and the tire has no belly at all so the rim actually sticks out further than the tire.
