If you need better longevity, equip more touring style of tires. Fronts usually are supposed to outlast rears, it sounds as if you need more air in the front and possibly your suspension tuned to your weight.I mean,my fronttire is ready used after about 2000 Kilometers...
But the rear tire is good enough for about 1500 Kilometers more...
When i now want to make a longer trip with about 3500 Kilometers,than i got problems at the front...
At my 1199,i used the Diablo Rossolll and no prob at all over long distances...
Maybe its possible in this way for a long run in combination??��
