I've been running 225/45R15 on 7" and 8" wheels and they worked fine. But now that I need new tires I'm going to 8s all the way around and debating about stepping up to 245/40R15. Anyone have experience with 245 on 8" wheel? It's within spec from Hoosier for that tire and through email correspondence with Hoosier they said it would work fine. I also asked them about building heat in the tire since I struggle with that on the 225s already. They said that yeah I would build less heat but the cooler 245s would generate more grip than slightly warmer 225s.

Guys... Thanks for the info on this. I am looking at getting some Hoosiers for the 4.0L car for using in AX. I have 16x8 design 90 rims to run them on, but I am concerned about them hitting in the front. I can adjust them with the spacers required to put the design 90 wheels on, so hopefully 245x45-16 A7s will fit. Thanks Clay Unfortunately I would take my experience as directional only since I have fiberglass flares on the car and steel ones on the shelf still (IMG:style_emoticons/default/dry.gif) To gain confidence that I could fit the 245R15 A7, I cut a disk the diameter of the tire out of a sheet of 3/4" plywood, drilled the bolt pattern in the center and bolted it to the spindle. Made it pretty easy to take measurements to all of the pertinent points with the weight of the car on the suspension. By measuring to the back side, the face of the plywood that was against the spindle, I was able to calculate where the tire edges would using wheel backspace and tire width. |
