If you're in the FF70 group you have no restriction on tires. I'm thinking of running take-off R35's, as they're available more so than R60s at the same price.. and I don't want to burn my good R60s because they need to last the rest of the season.... and I have a spare set of rims with completely shot R60s...
Any thoughts? Am I missing anything that would prevent me running the 35 tire?
Cheers,
Mike
