What size slicks and rims?

[smokedchevy]

Go with a 15" rim because you want more sidewall deflection. You can probably fit a 26x10" slick on a 15x8" inch rim. I used to run 28x10.5 MT sportsman on my GT but they're too fragile for street use. They fit right in in. I had to roll the fender and cut the rear panel on the inside. I rolled mine with five fat guys and a baseball bat. Paint chipped a little. The proper way is to cut, pinch, and weld. Can you say $1000 in body work? Don't waste your cash on radials. Get one set for street and then have your drag only tires.
