i think you answered your own question weeksy only you the rider can tell when a tyre has had enough .heat cycles do more damage,tyres hot then cold. instructers dont teach riding on there own bikes if you get what i mean,and they are not worried if they bin it.most slicks are directional.directional is how the carcass of the tyre is built so to take the stress,s involved i will have written tech data on the day that may be of interest to you cheers steve |
