The tires I use are out of production Conti Top Touring 2000 26x1.75. They have an advertised weight of 690 gm. Not terribly high performance, but they roll nicely and I like them. I don’t get flats with them.
I just got some 26x2” Schwalbe Marathon Extreme for my dirt bike. I have only ridden them up and down the street so far. I was going to take them into the woods, but it rained and I wimped out.
