Tire mileage

[Ghost_diver_imp]

Hi guys

I'm running the stock Bridgestones on my cb1100 and the front tire wear bars are showing after 8500 kms (a replacement has already been ordered). The wear is even, and, although the bike has done some kilometers on the highway, most of the time I ride on side roads. Most of these kilometers were done with a pillion, and the back tire looks fine, with plenty of rubber left on it.

I was wondering what your experience was with this? Is this the normal mileage for the BTs? Is it usual for a front tire to wear out before the back one?

Thanks
