Question: what is the pressure range in psi of this tire? I need a replacement for my tandem.
Document: Recently retired and at 65 years of age, I looked in the mirror and saw an old fat guy. The doctor told me that I would need to quadruple my dose of statin drugs to survive. Blood pressure was way high and I got out of breath just by talking for more than a minute.Something had to be done.
I put these on 2 mtn. bikes that my wife and I ride mostly on country roads with sand and pea gravel along the sides. 50 psi in hers and 60 in mine seems about right. If you need to get off the road quickly the tread is able to deal with it. Works good cutting through the grass and on hard packed dirt also. Rolls fairly easy and fast on pavement and I am quite pleased with them.
I used this to replace my mountain bike tire for which I could not find a replacement. I then did about 20 miles on packed gravel and no problems yet.
I'm just a casual MTB rider, so when one of my original knobbies that came with my bike got a flat I went looking for a less aggressive replacement tire. These tires are just the trick! They've got a bit of tread that can accommodate light gravel, but they are really geared as mountain bike tires for the road which is 90%+ of my riding.
I've been riding on these for a few weeks now and I'm happy with them. Smooth and quiet ride, holds well on loose gravel and dirt roads, I was worried that they would slip or follow the ruts when I moved off of the edge of the paved roads onto the dirt medians to avoid traffic, but they held firm. No problems with flats and I have the pressure pumped up real high, I'm a bigger guy and with my weight and the high tire pressure on sharp gravel I've had no problems.
I use a mountain bike for my commute mainly because of the dirt road I live on but I wanted (needed) a tire that wouldn't drag me down on the highway. These fit the bill perfectly. I started commuting (part dirt road, part pavement) as sort of a fluke and at 9200 feet above sea level, I need all the help I can get.
I bought one of these tires as a replacement, and fell inlove with it - bought 3 more... the center tread ridessmooth, yet has some tread, and the lateral treadwidens out for rough terrain. I put tire liners andpresta valve tubes in, and its a great combination.March 31, 2007... maybe not a five star...the tube startedbulging out the weak sidewall...then a blowout...replaced thetube, now the same thing at 35 lbs.
I had to stop and rest at least four times when going each way.The knobby tires on the bike made it feel like I was riding through deep sand even if pumped to 50 psi. I needed something better and without knobs.I did some research to see what size tires would fit my bike. Just because you have a 26 inch rim, that doesn't mean that any old 26 inch tire will fit.
These tires were on my single-speed commuter. I bought them as an all-rounder, since my 6-mile commute to campus includes gravelly shoulders, broken pavement, etc. And I wanted something that wouldn't be frightening in a little bit of snow, while not being slow like a MTB tire.My bike is a converted old steel MTB frame and with panniers (and me), it's a lot to pedal. The tires ride well and have reasonable rolling resistance at 70 psi.
I used Michelins on other bikes with success, so I went with these for my Worksman bike. The wide tread and high pressure are perfect for my daily commute, and will serve me well when snow flies.
Answer: yes
