My first GP5000TL lasted an insane 4-5000 miles - a full year. I don’t know why. My 2nd and 3rd GP5000TL lasted around 2,500 miles. These are all rears. I’m still on my original front tire. I’m too lazy to rotate.
I used to use GP 4000s and 3000s until they squared off. The GP5000TL doesn’t seem to square off. Both times I reached the casing and was surprised. I never look at the wear markers. How many miles do people get if they go by the wear markers?
I got about 5000 miles on my last GP5000 (32mm rear) and my front 28mm is now over 6000 miles. That said, I try to keep things moderate, avoiding hard accelerations and trying to keep braking smooth, rather than hard. If I was racing crits, I don’t think the tires would last that long.
Not only does the rear have more weight, but the surface patch is under constant tension (when pedalling, at least).
