I tried the TRC tires and consistently picked up .2 per lap on the first run with them.That didn't last long though, because on the second run they started to peel/tear horribly, even with some CA added where the tire meets the rim. If it weren't for the tearing, I'd switch. However, I do love the TRC wheels. For now though, it's back to BSRs and their crack-o-matic CRC wheels.
