As a 56 yo 15 mi. round trip commuter and casual rider I find that the K40's 27x 1 3/8 has a better ride and a more solid feel than the K 35's 27x 1 1/4 that I have on another vintage bike that I also ride. I prefer a blackwall tire but for the price I cant complain.
This tire wore over a year on a short commute (2 miles) back and forth over shoulders, in highway driving, and small town biking. I would recommend this tire
for commuting, and road trips(under 50 miles, one way) They also make a Kevlar center strip tire,which I have also used and highly recommend that.
I have been biking over 40 years, and know quality tires, Kenda always comes through.
