I have an R3T...went with a General Altimax HP, 205-60-16. Local shop mounted it for me today - no charge. I tipped the tech, then bought 3 oz. of Dyna beads. Got home, re-broke the bead (REAL easy), poured in the Dyna beads. Then aired it up, installed it, and went for a ride. I love it!! If I did not already know it was a "car" tire, there's no way I would have guessed. Absolutely ZERO noticable differences vs. "bike" tire. except of course, the new tire actually has some tread on it. LOL! Rear braking is much improved. After I wear off the mold release, I'll really put it thru it's paces.
Here's the recap: $90 instead of $250; superior braking and acceleration traction; no noticable handling differences; 30,000 mile tread life vs. 5,000 miles.
I love it.
YMMV,
