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.
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.
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.
I am a casual rider that puts about 800-1000 miles a year on my bike. The roads that I ride on are country roads that are rough and full of pot holes. These tires hold up just fine under these conditions.
I was fixing up an older 12 speed bike with decayed tires, and these did the trick. Looks just like it would have back in 1980 now. The one thing I'm not crazy about (and you can see it in the picture) is the mold fingers of little rubber on the tread and sides. They can be pulled off, it's just annoying and time consuming. More expensive tires don't have those.
But that's a quibble, for retro bike rehabbing, these are great.
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.
