I've thought strongly about R1R's for my FRC. But they are soft, and you will need to shave them. I'm fine with that because I know how stuff works, and that this is how the game goes. TW rating doesn't stop that. If you don't shave them, you won't like them, and they won't last.

Name only change?
NOTE:
At the end of 2014, Toyo changed the Uniform Tire Quality Grade (UTQG) of their Proxes R1R Extreme Performance Summer tire to reflect a 200 Treadwear rating.
UTQG ratings for Treadwear, Traction and Temperature are based on tests conducted by tire manufacturers and reported to the National Highway Traffic Safety Administration (NHTSA). These regulations allow tire manufacturers to under-rate their tires’ capabilities, but prohibit over-rating them. UTQG ratings are required to be printed on their labels and branded on tire sidewalls.
Toyo assigned the 140 Treadwear rating to match the UTQG Treadwear rating required by competition rules when the Proxes R1R was introduced, however subsequent Toyo wear data revealed the tire line earned a 200 Treadwear rating.
With some competition rules now requiring higher UTQG Treadwear ratings, Toyo decided it was time to officially change the Proxes R1R line’s rating to accurately reflect its capabilities.
Since 140- and 200-Treadwear rated tires will be available*, both currently appear on NHTSA’s safercar.gov website for the Proxes R1R line.
No changes were made to tire compound or construction, so both 140- and 200-Treadwear-rated tires are compatible with each other when put into service as singles, pairs or in combination.

But I guess it makes more sense to make a rule that's so lame they can't enforce it to the point that even if a tire meets the rule it can still be put on an exclusion list arbitrarily, AND to go back to tires that are better shaved so people have to spend more money on that.
