I have been autoxing in FP with 23x9x15 goodyear cantilevers on 15x7's for the last year. I have heavy steel wheels and would like to change to a lighter wheel. Would I be better off going to a 15x8 or should I stay with the 15x7 size?

Thanks

According to the Goodyear site the tire is intended for a 7" rim

... so you are probably won't gain much going with the 8". That said, I used to run Hoosier 23x9.5x15 on a 8" rim with decent results.

If you can afford it, you will see a big improvement if you get away from the cantilevers and go to the square wall slick on a wider wheel. But you probably knew that.

Thanks tom,

I still drive my car on the street and do not have a tow vehicle or trailer so I have to be able to get the wheels and tires into my car to go to the races. I can barley fit the cantilevers now, I don't think I could fit the larger wheels and tires in there. Eventually (years from now) I will get a truck and trialer and a dedicated race car, at that point I will definatly go to 16x10's and stiffer springs and shocks and all the other chasis reinforcements.

A couple of years ago I stumbled into your web site. I think it is great you put all the info about your car on the site. I know other people that try and keep everything a secret. Those are usually the people that do not drive well anyway. Congratulations on your nationals finish, looks like your suspension changes are working out for you, plus your obviously a good driver.

Another alternative would be to get the little trailer from Harbor freight or Northern Tool and tow the tires to the races... but I've always been a bit nervous of a bumper hitch on the early Z's.

Glad you find my website helpful. I figure if I kept everything secret I just might end up racing alone (I almost am anyway). Let me know if you have any questions I can help on!
