I put the subject tire, Avon CR6ZZ's, on the GT40. The tires are extremely good, that opinion formed after a few track days. Although tread depth isn't much, tire wear wasn't measureable. They stick great, don't dart and provide a reasonable ride for a race tire, which softens the financial blow . . . them suckers are expensive. Check out SASCO's listing for Avons.

Tire Specs :: SascoSports

I installed 225/65R15's front and 295/60R15's rear. The wider 245/60R15 wouldn't work on the GT40 due to its height, but no problem. Handling was neutral . . . no tuning necessary. The 245's should go on a Cobra, though.

Get the Avons CR6ZZ. It is one of the best improvements you will do to your handling department. Nothing better exists for 15" wheels.

I have logged over 18,000 street, strip and track miles on Avon CRZ66s.
(I am on set #3). In a nutshell, they transform a muscle car into a super car.

Thanks.

For those that have used them on Cobras, exactly which sizes did you opt for? I would like to preserve (inso far as I can) the look of how the tires fill the fenders, etc.

Avons seem to rate their sizes a little differently. The 245 might be a little too wide for the FIA. The tread width and diameter of the 225-65 is almost exactly the same is our standard 235 size.

Thanks all!

After last weekend's ERA Berkshire cruise, wife Suzanne has hidden the keys to the ERA289slabside (she did some 10 plus hours driving the little car and had a ball) and it's clear that I am relegated to the ERAFIA for all future drives. I've put on a full windshield, will swap out the old Shelby GT350 R model seat and take off the Goodyear Blue streak tires, all to make the FIA survivable on our wonderful roads here in NY.

The sacrifices one has to make for domestic tranquility...

Jim
