Re: High speed tires
My bike has Duro tires and they seem to be wearing fairly fast, at least the rear tire. That could be because I only have a coaster brake and it locks up and skids the tire often. The front seems to grip the road well. I run the rear about 45 psi, 5 over the max recommended.
I like the look of Sweetskinz tires but everyone tells me they're soft and wear fast.
