Hi, have been using my GR80 for 50K now. Rotated front to rear every 10K. Wear rate is even between inner and outer of the tire.
But the previous front tire which was rotated to the rear looks bald on the surface. But there's 0.6cm thread more before hitting the threadwear indicator in the inner tire as well as the sidewall triangle threadwear marker.
Tires grip well in wet and dry. Just a little noiser than before.
Its 1yr 8month old now.
Should I change based on the thread wear marker or just by eyeballing the surface?
Thanks!
