That is sick!Heidts 66 at the suspension Challange this year had 275's all the way around.It was in Super Chevy recently.This is the car 275-35-18 all four corners. 8 inch fronts with 5.7 back spacing
I tried my rear tire on the front and it won't clear the lower front edge of the fender. The rears are 255 x 45 x 17 with 8 x 4.5" BS rims. A 245 x 45 x 18 tire is even taller . Look in this section for the tire calculator, I like the bottom one on the list ,rimstires, you can compare 2 tires side by side.Thanks for the inputs and opinions. It looks like a 18X8 with 5" backspacing should do the trick for a 245/45.
