I haven't ridden an inch with my new t63, but impressions thus far---
GREAT looking DS tire. I like the big lugs that will offer great protection from rock tears and really protect the carcass better, I think (hope)
Holy heck, this thing is a bear to install. It has muy fuerte sidewalls. Once you get the tire on, however, this is a good thing. I'm willing to bet I could probably run this thing flat, or almost, and still be okay.
I opted for the 130/80-18
Now, the tire that came off was a regular MX non-DOT knobvie. Dunlop or something. It was a 110/100. I'd read the Michelin tires are measured differently, and tend to be on the narrow side. After a side by side, I'd have to agree.
The 130 t63, and 110 MX are almost the same width.
That said, the roll-out of the t63 is significantly longer. Hard to tell where the sidewall stops, as the transition is a curve (which will help road manners) whearas the mx. Knobbie is not.
