After trying unsuccessfully to get my car to work on slicks, I put on a pair of 295-65 drag radials after one of the tech guys at M/T recommended them to me. Runs much better on the radials.

I've been a best of 1.32 sixty foot and 9.54 at 140+ mph on the radials, footbraking and naturally aspirated.

The best I've gotten from it on bias ply tires is a 1.43 sixty foot and a 9.94 at 138+ MPH. Given the conditions I ran that in, the bias plies will MPH slightly better b/c they grow. Radials don't grow much, if at all.

In the bias ply tire's defense, I only have 8.5" wide rims and was running a 29.5x10.5 stiff sidewall M/T slick with tubes. I had to run 18 psi in them to keep from folding the tire up. With a wider rim I think it'd do a lot better.

The radials are faster when the track will hold them.

I recently ran into some major traction issues, but learned a valuable lesson about how important the front suspension is to making a small tire car work. It's all fixed now and runs like it has for the last 4 years.
