    Bought a shwin 26 mountain bike with aluminum rims. So last night, my rear wheel hit a raised man hole cover...blew the tire out and possibly dented rear wheel..second time in less than 2 saddle bags in back with my tools etc..and I'm 230. Do I need heavy duty rims? had to call for a ride again..this has got to stop!

    Some people on here have reported success with the No-Mor Flats Solid inner tubes. They are apparently a pain is the neck to put on, but I would suspect they will work.

    Here is an unfortunate link from Wally World. I wish there was still an American bike company around.

    not exactly sure what we got going on here
    you mention two blow outs
    I understand your second blow out - not sure what happened on the first one ??

    when ANYONE hits one of those raised man hole covers ---
    without knowing what's coming
    we are in for some trouble..

    we know that you have learnt you lesson now --
    all man hole covers, water valve covers, storm grats ect -- CALL FOR SLOWING DOWN
    I hate it when I hit one of those
    and if I may just a little note here from a retired City worker
    if one of the Cities man hole covers is raised
    and someone bends a rim because of it
    the City has to pay that one the cost or repairs
    their is a max limit that most Cities allow for things sticking up -- such as 1" for some
    but to also remember -- City payoffs do come slow

    bact to the point -- two blow outs
    maybe you wish to consider a top quality rear tire -- most of the weight is carried -rear
    there are also super heavy duty tubes and I also use those plastic tire liners

    after this little mishap -- be sure to check for broken spokes -- is your wheel still true ??

    ride that thing

    Hi mountainman..First blow out was a sunken section of the time I saw it going 25mph, it was to little to late..I jumped the front wheel and when the back wheel was going to hit tried to releive the pressure on back wheel to no avail..dented the rear I'm on top of this bidge at night on my back trying to fix the bike and the cops show up..I tell them the situation of the sunken slab of side walk, he asked me for my I.D..not my licecense and asks if I need a ride home, I reluctantly said yes.. I go by the sidewalk 2 days later to see what the he$$ I hit...and low and behold they put asphalt over the concrete sidewalk making a bridge lmao and that was state bridge not my local town...Hmmmm
    anyway back to the second rear wheel blow out...just fixed the tire this morn and it looks like the tube got pinched then popped becuase the rim wasn't dented this time...but still....Heavy duty tubes/liners/kevlar/...? I need to stop having my tires get blown out at night on what seems like most bikes should go over or at least not "pop"...gee I'd hate to see if I took this bike off roading..I'd better have a dozen tubes with me and a rim! The bikes brand new. ???????? help...thanks

    well you mention riding at night -- yes I have also found to be a problem

    I don't have the best lights --
    I hit large rock one morning in the dark -- almost thrown into traffic

    I am slowing down my rate of travel in the dark now

    be careful while in the dark and you -- ride that thing

    If your going to have wheel trouble 90% of the time it's going to be with the rear wheel(simply by the weight over the rear wheel)
    Make it a strong as possible...heavy duty hub/dual-walled rim/thick SS spokes & then get your tyres as bulletproof as possible.
    OVERKILL is the name of the game,particularly with the rear wheel.

    Fetor..thats exactly what I'm thinking...make the rear wheel as bullet proof as ya can...thanks for the reply

    mountain..just got back from a long ride..what a great fall day for that...I also stopped by the local bike shop and he said I could go over the psi range of 40 to 60 by 10 psi..just filled both tires to 70 psi...I think this will help alot.. looked into a 100psi tire but it was more of a road tire and winter is coming up I'll think I'll stick with my mountain tires at 70 psi...also might add a liner for those rocks and such..bottom line though your right...slow down at night...I wasn't familiar with the area...thanks for the help

    I'd go with a meaty tire such as the Maxxis Hookworm (26x2.5) if they will fit within your bicycle frame & forks & a tubeless system.
    I've used this on 2 bikes with great success & am not affiliated with this company in any way.

    The only problem with those rims I see is that no matter how heavy duty the rim, it's only as good as the tire..I'll give you an example, lets say I put the heavy duty rims on and I got 60 psi in the tire and I hit what I did's still gonna pinch the tire against the rim...the rim will hold together, but you'll still get the "pinched" popped tire..hense I inflated my tires to 70 psi to minimize this from happening again...first one bent the rim...second one just pinch the tube/tire and popped it..hence the 70 psi now...we shall see if this works I got a feeling my tires where low when I bought it and never checked the psi till now whoops lol...thanks for the reply

    wondering if that's the same stuff used at work ??

    while operating equipment for the City (retired now)
    for the small wheels that seemed to get a lot of flats
    they would send them out so as to be filled with something
    after that -- never another flat
    maybe not the best ride (kind of hard) but never flat

    do you think that this may be the same stuff used ???

    ride that thing

    ok loquin -- you got our attention !!!

    now that looks to be A HEAVY DUTY WHEEL !!!

    did I miss it - or - do you have the link handy

    I love that brake and the ten gage spokes !!!

    ride that thing

    if you want the comfort and lightness of air filled tires but still want the toughness of solid inner tubes I suggest you check out Specialized's "Armadillo" tires, they're made out of Teflon and claim to be the toughest tires on the market.

    Ive had them on my Felt for a while and have had no problems at all.

    also they have a red stripe lining the side which looks pretty cool IMO.

    That looks like a very nice wheel...probably comes with a nice price tag to..I'm going to try psi of 70..seems to be working..will keep this in mind just in

    I agree with most all the things stated above. However I'm not sure if I would trust a tire inflated over it's max with the extra weight of an MB over it. When you get that things heat up from riding the tires internal pressure will rise and all it'll take is a sharp rock or piece of glass to have that thing literally explode or get a big tumor bulge in a compromised section of tire. I run my Continental Town & Country 26x2.1 tires at 60lbs and they're rock hard at that. Overinflated tires, especially on non-suspension bikes, may compromise your traction with the ground as every little bump you hit you're going airborne.
    I think having a balance of heavy duty tires/rims/hubs on front and back is important. I know when it comes to a normal human powered bicycle sacrificing some strength for weight reduction is preferable but with the punishment we give our bikes "mopedizing" both wheels as much as possible is the way to go. Heavier wheels will generally give more stability due to a greater amount of rotating mass as well. This keeps both of your wheels from failing AND helps to keep you upright and off the pavement.

    Bummer... I thought I'd be the first to find that site. That tubeless system is definitely worth someone checking out, tho.

    I stumbled across a video from that site, that is pretty amazing to me:

    There's an installation video to see how it's done:

    A page about the tubeless system:

    And the FAQ, that gets down to the meat of the problem (stuff might not last longer than a few months, and then needs to be "refilled"):

    Who's gonna try it out? I'd rather try that out than a No-Mor Flats foamy thing or an AirFree extra bouncy & slippery tire... but at the $60 price range, just some tube liners for both sides (rim & tire sides) might be better in the long run. Somebody try it out!! For claiming that the pressure will never decrease, when a normal tire/tube loses 1 or 2 psi every week... it's definitely worth a shot for that alone. And did you see the demo video? WOW... buy it NOW!!
