We are a bicycle mission organization and many bicycle come with dry-rot in the tires. The reasonable cost of this tire allows us to make use of the bike for those in financial need.
I was a bit put off by these tires when I first mounted them because they did not appear to be seating evenly. I suspected that they might be slightly larger in diameter than spec. However, by deflating and re-inflating them several times I was able to mount them in a satisfactory manner. Once mounted, they have given me no trouble. I have about 375 miles on them at present - all on paved surfaces thus far. Their somewhat triangular profile appears to work well to reduce rolling resistance while the large cross-section provides the shock absorption and grip in the slippery stuff that you'd expect from a 27x1.25 tire.
Mounts easily on the original Schwinn steel rims. While I purchased these tires to allow me to continue to use the Continental on an indoor trainer, I may actually take the bike out occasionally to just see how it rides on the street again, something it hasn't done since the 1980's.
Using a bike on a trainer usually results in quick rear tire wear, but I've been pleasantly surprised at how little the rear tire seems to be wearing on the trainer, which after hours of use still shows some flashing from the molding process on the center rib of the tire. Also, I'm not finding a lot of ground up tire residue around the trainer as I did with the previous tires.
These tires also preserve the look of the original skinwall tires the bike had when it was new (which was about 1970).
I have gone through three sets of these tires as a bike commuter in Seattle. While a great value for a weekend rider, these tires age fairly quickly under heavy use. My current set has cracks in the sidewall despite never filling to the recommended PSI. I think that these are good for the occasional rider but someone who relies on their bike should consider paying more for a more durable product.
Ive only had these tires on for about a month now, but they seem to wear great. I notice 90 psi is recommended, but that ride was a tad too bumpy for me, 80 psi seems about right. These tires are a steal for the price and the shippping was quick. Definitely recommend the K35s for commuters!
