I thought I posted this thread a few days ago but I don't see it so I must have done something wrong so I will try again. If you want to try these don't wait untile your tires are shot. It took me a week to get the rear and 2 weeks to get the front. One of the features of this tire is it is supposed to be ready to ride hard as soon as you get it up to normal opeating temperature. I rode to ortegay highway 74, a road I am very familar with, I started out easy on the way form San Juan Capistrano over the hill and down into Lake Elsinore. This is in Southern CA if you are not familiar with the area. Going back the other way with only about 75 miles on the rear tire I pushed almost as hard as I ever have. I would never have pushed a new tire this hard if it was not for three tire tests I had read talking about how great they were right off the rack. I get the front this monday 4/11 and will report back after I have put a few hundred miles on them. The real test will be how long they last. I got 7500 out of my rear roadsmart and could get probaly another two out of the front if I was not afraid to leave it on any longer.
