    Nu-Teck Airless

    I read about Nu-Teck Airless tires in another thread and I'm curious if anyone uses them and what they have to say about them. I'm intrigued, but the reviews are a real mixed bag. Although it hard to tell if many people are talking about these airless tires or just airless tires in general.

    Really? You found reviews by people who liked them?

    I tried them, not impressed. Good for trailers only.

    Falling off rim- true
    more prone to slide in turn- true
    slower- true.

    Go with Schwalbe Marathon Plus tires. I did, and never looked back.

    Note: I tried them with an open mind and a sincere hope they would work. They did NOT.

    Yea, I did. I guess when something seems to good to be true, it probably is. I don't get flats very often, but I like the idea of not having to have all the stuff to fix a flat.

    The problem with tires like these is that they don't deform the same way that pneumatic tires do. Because of this, your cornering traction will be much lower than with pneumatic tires.

    I have them on my bolt-on single speed. I like the one in front, but not the one in back... same tires, same wheels. I have the 20c and will try a 28c next for the rear wheel.

    I am very fond of my Schwalbe Marathon Plus tires.
    I see unexamined people. All the time. I don't think they know they're unexamined.

    Haven't tried the Nu-Teck, but I have something that's very similar in design and material: http://www.greentyre.co.uk/26inch.html
    I've even gone to the effort of making one into a winter tire by putting studs in it, as fixing a flat along the side of the road in freezing temperatures can be outright nasty.

    And the verdict is:
    - mounting was a pain. I'm so glad that the enclosed mounting spatula didn't break. If it had, I'd still be picking plastic shrapnel out of my body. Eventually I resorted to using a carpenter's bench as a rack to stretch the tire on to the rim.
    Knowing how hard it was to get them on, I have no fears of the tire coming off unintentionally. If you read up on the stuff you'll find the manufacturer's stressing the importance of having the correct fit between the tire and the rim.
    This is your first concern - first figure out which tires that'll be a good fit to your rim, then look for which tread patterns, PSI equivalents and widths that are available.
    I got about 200 miles on them before switching to my summer wheels, and they stayed solidly in place for that duration.
    - Mine have that elevated ridge in the center, so the pattern isn't that good for braking on hardpack. Next season I'll cut some notches into it.
    - cornering on hardpack/ice is pretty much as I expect from the number of studs I'm using.
    - on wet tarmac they're nothing special either way. No surprises.
    - grip characteristics seemed to change once the surface from the mold had worn away.
    - on cobblestones and when crossing thickly painted lane markers they're definitely more squirrely than any regular tire I've ever ridden. Still entirely manageable though.
    - dry tarmac is entirely uneventful
    - If there is a difference in rolling resistance, it is smaller than all the other differences that influence my regular rides. But then I'm using what's supposedly a custom, 65 PSI equivalent. YMMV.
    -on smooth roads I have no issues with these, but they do ride very harsh on uneven ground. Passing a curb, even with the best of intentions deliver a bone-jarring impact.
    My rims were OK, but I can certainly see the potential for trouble there. But then I'm using what's supposedly a custom, 65 PSI equivalent. YMMV.
    - biggest objection I have is the ride quality and the temperature dependency. For the weather range where I most wanted to use this tire it's like riding directly on the rim, quite bad actually. But when days turned warmer the ride was/is OK.
    - I will admit to being worried by thoughts of wheel survival. Impacts are harsh. But 200 miles kinda hints that it might not be as bad as I think.
    - had a good look at them when I switched to summer gear, and they seem to be wearing rather rapidly. Can't tell yet it it's just more of the mold features breaking away, or if I'm beginning to lose functional amounts of material already.

    In all I'll say judgment is still pending. Mine are supposedly extra hard, so they ride extra harsh. Had the result gotten closer to the stated PSI equivalent in the temperature range where I most wanted to use them I'd probably have been more pleased.
    It is nice though, being able to coast right through patches of broken glass in blissful unconcern.

    They should probably be seen as a niche product. They're different, and there is a trade-off. For some it will be worth it while others won't like it. But if you're troubled by flats and have the money to spare it's kinda silly not to try them.

    I dunno about that. The polyurethane used in these tires is a close cousin to the polyurethane used in inline skade wheels. And on clean tarmac it feels like my ankles would snap before the wheels would break free.
    Maybe it'd be a difference it you're riding aggressively, and really pushing it. But I haven't noticed any issues with cornering on dry roads.

    Thanks for your input everyone.. I think I'll just buy a direct replacement for what I'm running since I'd have good luck with it. I just like the idea of one less thing to worry about.
