Continental has tried to combine grip with high mileage on their Trail Attack. They 'bake' the same rubber at different temperatures, so that shoulders are soft for grip and central pattern is hard for mileage. I've driven Conti's Trail Attack for 13500km, and there's still some thread left. The high mileage is comparable to Tourance, but Tourance is built for stability, Conti's TA is more fun to drive in twisties.
This all seems promising, but still I'm not overly impressed with these tyres (except for mileage). From the beginning, the rear has slided away a couple of times, in twisties, where there was no clear cause (roads not slippery).
I've read on here that these tyres don't warm up fast, so perhaps that's why.
Anyway, this never happened with my other tyres. For statistics : with identical tyre pressures, and suspension setup, and while my behaviour hasn't changed in comparison to riding on Anakee, Battlewing, Tourance.
What's worse : depending on how many twisties you do, the shoulders wear faster than centre, leaving an awkward wearpattern.
Usually, when tyres wear, they flatten, but the crossover to the shoulder is round. Not so with these tyres. What you're left with is a more or less bumpy ride, and a loss of grip, exactly when you need it.
Since I'm only interested in grip, not mileage, I won't be buying these tyres again. I realise that others may have better experiences. But if you search posts, you'll find others with similar experiences.
