Hmmm, it is really bad when the tyre breaks away. I have the T63 on my Tenere now for 3500km. I love them and I feel very save especially in case of wet streets. Yes there is some noise but I like it and offroad it doesnt matter. I used them also for a trip to Slovenia - with panniers and tent and and and... packed onto the Tenere - there was/is no problem with the tyres.
I feel good with the T63 and i'm looking forward how much km i can do with them...

Cheers
Thomas
