Falkens - Difference Between Rt215 And Rt615

[scathing]

well of the 615's are replacing the 215's that answers my question hehehe

Word on the street is that the RT615s will last longer (treadwear rating of 200 vs the RT215's 180), and they have better wet weather grip. I'm rolling on RT215s at the moment, though, and I've found their wet weather performance to be reasonable.

As stated by others, I'd only use RTx15's on a weekend street car, or for hillclimbs. The tyres lack the out-and-out grip, and heat capacity, of proper R-Comp semis. At the same time they don't last long enough to be put on a daily, unless you've got a big tyre budget or you need the grip because your car makes monster torque off idle.
