whats the best size wheel/tire for a front "skinny"

i'm getting 15x8 TT2's for my rear with 275/60/15 m/t street radials. I was going to do a 15" on the front but have never run a skinny and I was wondering if we could get a discussion on what the best overall size for a front wheel/tire is? how narrow is too narrow? What is the point of going to a narrow tire? What is the different with going from say a 5" wide wheel to a 7" wide wheel?

Re: whats the best size wheel/tire for a front "skinny"

For the street, I would go no smaller than 195/65-15 because of the weight.
Smaller tire width, less tire contact, less rolling friction, less upsrung weight.

The difference between the 5 inch wide rim and 7 inch wide rim, providing both have the same backspacing, is the scrub radius, the relation between the SAI, steering axis inclination, and the centerline of the wheel. the two meet together at the road surface, as in a stock set-up and offer the least amount of rolling resistance and tire wear. Install a wider wheel and centerline moves out causing more resistance, a longer lever so to speak, but greater road feedback.

so what would you recommend for a fast street car? I was thinking a 6" wide with something like a 205/70/15 My car has 3rd gen power steering with a 2004r with a lockup converter and will pound the pavement/highway a lot!!

that looks great! What's the backspacing on the front wheels? How is it driving around with such a skinny front tire?

This is good information as I've had the same questions. Just got my 15x4 Street Lites shipped Saturday and can't wait to get some rubber mounted up and get 'em on the car.

They're 2.25 standard bs 15x4 welds.are very stable on the road and at speed. Long ago i had 15x3.5 superlites with moroso 7.10x15 drag fronts that were just plain scary in a panic stop!they would lock up the second you stabbed the brakes.

205/65/15 is really about as narrow you should go for any real street driving
