    Well that didn't work, lost a full second by adding a 1" of width.
    Went from 255/45/20 F1 Supercar Goodyears to 295/40/20's
    Look a lot better on these 9" stock rims

    What the heck are you SC people doing for tires.
    I just spin in 1st and Second with this stock 6.1
    It is going to be scary if I can just get HOOKED UP :)
    Maybe 275/35/20's?

    Well I have come to the conclusion these tires are just to hard of rubber.
    O-Well they were cheep, good burn out skins.
    Dropped the rears down to 25 lbs, and picked up a little, but still not even as good the F1's

    (anyone catch the ROOTS reference on the current mileage)

    I replaced my OEM Pirelli P ZERO NERO ALL SEASON 275/40/20, which have a 400 tread wear with 275/40/20 M/T ET Street S/S Drag Radials, which have NO tread wear rating and picked up a full second. Use them at 20 PSI at the drag strip and about 28 PSI around town to reduce center wear.

    Went from spinning and wheel hop to almost perfect hook up each time. But they come at a price. About $370 per tire. Plus they're not going to last very long. It's not my daily driver so I don't put many miles on them. But I do leave them on all the time. So much nicer not to worry so much about a little wheel spin when taking off a bit spiritedly from traffic lights, etc.

    There are a lot of different Pirelli P-Zero tires. I know the P-Zero NERO All-Season, that came with my car, were terrible for traction.
    If you're looking for an improvement in traction I would look into the traction rating of the tire, which is more important than just an increase in width.
    Ideally a separate set of wider rear wheels with stickier tires is the way to go, if you can do it. But if you're force to get All-Season tires for your daily driving, it makes it tougher(and more expensive) to get a reasonably good traction tire.
