The tires arrived quickly, fit well, and were easy to install on my ancient Nishiki Sport. I don't ride a lot, only 3 times per week for 30-60 minutes each, only on pavement, which is almost always dry. I like the ride from these tires, and they seem to be well-made and durable. Very satisfied with the product and with the service from biketiresdirect.
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 used these new tires for an older Fuji 10 speed road bike and they ride really nice, the only thing I don't like is that gumwalls tend to dry rot after 2 or 3 years.
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!
I picked up a Schwinn Paramount tandem and got these tires so I could get the tandem back on the road not knowing whether my wife would fit as the stoker. i did not want to invest a lot of money in tires if my wife could not ride it. Once I got the tandem all sorted and we took the tandem out for rides, after 250 miles the casing on the rear tire failed right in the middle of the tire.
I emailed Bike Tires Direct with pictures of the failure and they sent me a brand new tire. I can't complain about their customer service. I moved the front tire to the rear and after another 93 miles that one failed in a similar manner.
I would have to say that I would not recommend these tires for use on a tandem given that I weigh 175 and my wife less than 110 and they failed with that weight on the tandem.
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.
This tire seems to work well on non-hook Dunlop Special Lightweight steel rims. I have ridden them now at 60 pounds with no problems. Really any higher on a steel rim, and an old Raleigh Gran Sport is going to be a bone shaker anyway.
Of course like with any non-hook rims, mounting and inflation has to be done carefully to avoid blow-off. Probably about as close as one can get to the original Dunlop hp tires.
This is a great gum wall tire with a great ride. Love the high pressure, makes for a smooth low resistance ride. This is a pavement riding bike used for recreational riding.
