I'm on a search for extremely fast large tires (more than 20 mph steady pace).
You see, there's a problem when tire manufacturers simply increase the size of a roadie tire. You get twice as much rubber on the road, but it is the super-sticky rubber designed to keep roadies from flipping. This makes incredibly bad friction for MTB owners. Remember 10 speeds and all the frequent crashes? Well, that was fixed some time in the 80's by super sticky rubber, but it is a miserable thing to have a large tire made of this stuff.
The only extraordinarily fast large 26" tire I can find is Schwinn Typhoon Cord, because it is not made of sticky road bike rubber. Being large, they do stick a tiny bit on glass-smooth concrete, but what a shockingly fast pace you can do on the tarmac (highway shoulders). I'd keep using these, but whitewalls just look goofy.
Surely there are other fast, hard tires out there that are road and gravel worthy?
I've seen the mountain bike magazines displaying competition tires, usually on the rear of the bike, and these tires have exactly the same rolling bricks (rectangles with tiny spaces between) as the Schwinn tire. I'm wondering if these are fine, fast, roadie-speed tires (20+ MPH easy pace) or if they are sticky like gum (15-17 MPH with considerable effort)?
Anybody have some good road/city riding experience with a big 26" tire?
P.S. I want a big tire because:
Stopping pedaling and just coasting at 19 MPH (or so) is just fun.
Big tires maintain the gear ratio and speed of the mountain bike (small slicks slow you down a lot because there are less inches traveled per pedal stroke--Yuk!).
Big tires maintain the character and comfort of the mountain bike.
Oh, and I don't want a knobby tire because I live in a city with 90 miles of pavement.
