You would probably get about 2,000 miles out of your rear tire and wonder why. Designed for racing, these tires are often discarded after 20 laps. Because of this, when a street squid runs out and buys what he hears is the best tire around, the reality is it's probably not the best tire for him. Make sure you know what the tires you buy were designed to do best. You want your tires to perform well, and you may associate performance with flat-out speed.
Performance means doing best in a given application.
Consider what you'll be doing and on what kinds of roads. Riders seem to fall off motorcycles with a set of fresh tires. The bike just slips out from under the rider. Tire manufacturers use a slick compound in the tire mold that ends up on the outside of your new tires. This makes them slippery.
