12.5in to 24in Tires
We run these tires on two trikes and have never had a flat due to a puncture. We've put many miles on them on a variety of surfaces......asphalt, gravel, dirt and crushed limestone. The puncture resistance gives you peace of mind when doing a long self-contained tour.
I have this on the front of my Bacchetta ATT 20 with a Kojak 26 in the rear. Smooth ride. Low rolling resistance. I coast faster then my wife on her upright with 700c rims. I've been riding primarily on the street, through tree debris in the bike lane and no cuts or punctures so far. Highly recommended for recumbents
I have found that the Kenda K193 Kwest 20 inch Tire (406) to be the smoothest and easy rolling tire, of all the different tires, that I have used on my Tri-Cruiser in 26,000 miles. I use mostly on hard surface Rail to Trails and local streets. I will be getting 3,000 miles or more on the tires. I have experienced 3 flats, one where the side wall was scored by a sharp grate end that was exposed on a bridge crossing. One where a thorn cut several cords and the tire failed. One puncture that posed no future problems. It is the best tire buy I have found for my Tri-Cruiser.
