pico Posted April 6, 2019 Share Posted April 6, 2019 I had a blowout while sharing the street with cars. Not funny. Really scary as all of a sudden you lose control of the wheel. It started pulling me into the traffic. Nice recovery. I wonder if sliming makes a difference since I never slimed a wheel. 3 Quote Link to comment Share on other sites More sharing options...
Popular Post meepmeepmayer Posted April 6, 2019 Popular Post Share Posted April 6, 2019 I love how Marty can't help showing off a little when crossing at the lights. I know the feeling My experience is different. Blowouts are positively harmless if you're going in a straight line (not in a curve or carving or on uneven ground). I had my inner tube explode - literally, I heard the bang and thought somewhere nearby something went wrong - at about 25kph. The unicycle simply behaved like a twig or something got stuck in the wheel well (felt like that mainly by the rubbing sound, not even due to bigger rolling resistance, it's self-balancing after all so that's not a thing), and I just instinctively and calmly stopped. Didn't even realize the tire was completely empty and that the bang came from the wheel before I had stopped and had a look and realized "so that was the bang!". It was surprisingly non-eventful. No instability or wobblyness. I assume the little bit of wobbling Marty had (it wasn't a danger of falling off) is because he did a little carving. 4 Quote Link to comment Share on other sites More sharing options...

Other than that... it really is no big deal, as far as I can tell. Quote Link to comment Share on other sites More sharing options...
pico Posted April 6, 2019 Share Posted April 6, 2019 On the other hand it was on the V5F that is not well known for it's stability. I guess different wheels must react differently. Quote Link to comment Share on other sites More sharing options...

Thank God for wives!!! All my wheels are slimed. This was a blowout (rapid loss of air). I believe the valve separated from the tube, which happened on the previous tube on this wheel.

Unfortunately I'm mostly carving when I ride Yeah, at the speed I was traveling there wasn't much risk of me falling off the wheel. Cruising at 20+ mph might be another story Quote Link to comment Share on other sites More sharing options...

Thanks Slime doesn't help when you have a large tube failure like what happened here, if that's what you're asking. Certainly seems to help with all the small punctures though. Yeah, it's amazing how uncontrollable the wheel is when there's no air in the tube. 1 Quote Link to comment Share on other sites More sharing options...

My last non-repairable Mten3 tube failure (after ~400-miles) was due to the valve stem separating from the tube. This is probably a week spot with most tubes. When I replaced that tube, it showed evidence of at lest half a dozen punctures that Slime fixed (you could see the little green spots on the tube. 1 Quote Link to comment Share on other sites More sharing options...

The valve stem can be ripped from the tube if the tyre pressure is too low because that lets the tyre spin on the rim and it drags the tube with it resulting in the valve stem (which cannot move) being ripped off.

I'm sure @Marty Backe has his pressure high and he's been through 2 tubes on his mten3 ,i usually run low that's how i like it for my road conditions 1 Quote Link to comment Share on other sites More sharing options...

The smaller tyres have less surface area pressing against the rim, which likely makes the tyre easier to move along the rim. I've noticed this problem on bicycles quite a bit and it can often be spotted by the valve stem tilting to one side. On EUC with brass valve stems you won't notice anything until the tube rips. Higher pressure helps, but most EUC riders set their tyre pressure very low compared to what the pressures would be on a bicycle tyre and this problem still occurs on bicycle tyres. I had this happen several times over the years. https://www.bikeforums.net/bicycle-mechanics/829699-bike-tube-keeps-tearing-valve.html Edited April 7, 2019 by Nic 3 Quote Link to comment Share on other sites More sharing options...
