wider tire and traction

A wider wheel will not lower your RPM. A 275/60R15 looks pretty silly on a 10 inch rim. A 10.5 slick will work on a ten inch fine. The difference in weight between the two wheels is in ounces=not much difference. IMHO your car is a street/strip car and I would buy one tire and wheel set up. A 275 drag radial is more than enough and if you cant get an 11 second car to hook on it then something is wrong with the car.

I know this. I was going to go 15x10 on the street with a 29in tire to lower RPM. And because the wheels are lighter with 15x8 I was thinking of just staying 15x8 for the track with a 28in tire and prolly a M/T ET street slick not a full slick but more of a radial or the m/t Radial, Which ever hooks better.
