Just have a question on original type vs. radials. Well, two actually. It looks like people prefer the original type, but is this for more of the "original" look or do they hook better? How many people are running originals vs. modern radials? Just wondering.

I'll begin with the letter of the law.

14.00 TIRES AND WHEELS AND BRAKES
14.01 Wheels must be correct, including correct diameter, width and material.
Note: Width may be upgraded to a maximum of 6”, if the correct wheel is narrower than that. Reproduction wheels OK.
14.02 All 4 wheels and tires must be same size.
Exception: Mopar TA Challenger came from factory with G-60’s on rear and E-60’s on front.
14.03 Original equipment reproduction bias-ply tires only. No soft compound tires of any kind are allowed. Retread tires are not allowed. Any car is allowed to upgrade to a maximum size tire of G-70 of the correct wheel diameter. All cars that were originally available with a 60 series tire can upgrade to a maximum size of G-60 tire of the correct wheel diameter.
Exception: First time Supercar participants are allowed to run normal ’non-sticky’ street radials for their first Supercar race.
14.04 Aftermarket or OEM brake upgrades are allowed for safety concerns. Every effort should be made to achieve a stock appearance.
14.05 Line locks are allowed if hidden.
14.06 Tire Tech; All the repop tire treads are similar in design, 4-6 deep circular tread grooves with smaller grooves and sipes within those rows. There must be evidence of the original main tread grooves over the whole tire to be legal. Any bald sections or patches where the original main groove disappears and the tire must be replaced.Most important if your tires are questionable, make sure you bring an extra set to qualify and compete with. Tires will be inspected before during and after the event is completed and must have all of the main treads showing.

Now with that said, the originals seem to produce the best 60' times. If you prefer to run a correct size modern tire you won't be hit for it until, your running very quick times.
First and formost SuperCars is about fun and putting on a good show for the crowds.
Bill

Radial tires flat out don't hook as good as the bias ply. The bias ply is softer as well as more flexible than the radial tires. The bias ply also gives the car the right stance and look.

When starting out if you don't have bias ply you can run the radials.

1.74 second 60' on f70 14 redlined. They hook better than you think. Welcome aboard! It's addicting! :pop :pop :pop
