The bl00dy tyre just exploded!

So it`s Saturday afternoon, I`ve been out for a knackering 40 mile off-road ride with my nutter mates, the sun is hot and I`m busy tyding the garage out (...the wife`s been onto me for weeks to about it). The dog is fast asleep on the lawn in the sunshine when all of a sudden ...**BANG** ....a bl00dy loud bang and I see a sort of mist coming from the corner of the house.
The dog $hits himself and runs off and I think WTH?
It turns out that my bike was sitting in full sunshine and the air in the rear UST tyre expanded so much it blew right off the rim spewing a latex mist everywhere!
..Is this normal? Has this happened to anyone else?
.....crapped me right up...

:shock:
you sure it was the heat alone, maybe a thorn had weakened an area earlier0 -
yep, happened to me this Winter when i'd just freshly pumped the tyres up. the tyre edge rolled onto and touched the radiator. makes quite a 'pop' 8)0

It´s happened to me a few times. Worst one was driving back from glentress years ago with the bikes in my campervan when there was the most unbelievable bang. I almost put the van off the road, I assumed something had hit us or exploded. It was the bike tyre. Must have been a nick in the tyre and it had slowly been opening up!0
-
I had a similar thing last year.....the day before it happened I'd completed a 30 mile offroad blitz...no issues.
Following morning, hop on the bike, get to the end of my road on the tarmac and "BANG".....the whole street echoed. Sounded like a shotgun. Not only had the tyre blown, but the whole wheel had gone with it. The metal of the rim had sheered in two!0 -
Surely if it was tyre damage it wouldn't bang so loud, just hiss as if you were letting air out of the valve. The bang must come from the tyre bead slipping over the lip of the rim (or blowing the rim apart).0

Why? Balloons go bang, this is like a very thick, much higher pressure balloon.0 -
Good point, I was thinking that the pressure increase just spread apart a small hole. If that hole was still sealed with latex until the pressure got enough to rip the tyre more violently so that most of the air could come out almost instantly (like a balloon popping) then I imagine it would go bang.0

lol, this happened to one of my friends bikes once, it was so funny, probably casue it wasnt mine lol0

yip...
a mate runs a bike shop in gala...
he says the ones to watch out for are road tyres at 110psi on a hot day in the sun....
they go boom.Whenever I see an adult on a bicycle, I believe in the future of the human race.

I had a spoke go "TWANG!" while by bike was just sitting in the hallway once. I hadn't ridden it for a couple of days and it snapped right in the middle. Most odd.0

I went for a night ride on Friday, and didn't get round to taking the bike out of the car until about 3pm the next day. As a result of sititng in the (black) car in the sun, in front of a baking hot black garage door for most of Saturday, the bike was too hot to touch! I guess I was lucky that my tyres didn't go! TBH, I'm surprised my forks hadn't exploded either!0

Happend to me on the way to school today, new wheels and tires with old tubes. I was riding through a junction when BANG, The front tube exploded, half the tire shot off the rim and a girl in front of me almost pissed herself.
Then a 20min push back home with 8kg of pannier on the back cause I didin't have any spares.And now you know, and knowing is half the battle

Just notived my bike had a flat tyre so sat in the garden repairing it, just running through the gears while the stand is out and I hear *Poptssssssssssssssssssssssss*, The other bleeding tube has gone too.
Worse bit is, Guess who only has one spare. :evil:0 -
blew a ghetto tubeless off the rim at 60 odd psi whilst forming the tyre (no sealant thank god)
Right next to my desk at the time, i was deaf for the rest of the day!0 -
Curiously, blitz jr's BMX tyre 'exploded' yesterday while it was parked up. I didn't see it but allegedly it did the poptssssssssssssssssssssssss thing and just deflated.

Maybe the PF is a winter beast and is not enjoying the hot weather? Bullying us poor people is hardly fair though.0

Oh shoot, I've just realised my Road bike with it's tyres inflated to about 110psi is currently in the conservatory which is as hot as hell and I'm at work! :shock:0 -

Mines definatly fine, 0psi as ive got double flats :evil:0
-
I'm surprised it makes that much difference. "Normal" inflation temperatures are probably something like what, 15 deg C? That's 288K. On a really hot day a black thing in the sun might get up to 80 deg C. That would be 353K. So pressure would go up by a factor of 353/288 = 1.23. That's from 40psi to 50psi. That's pretty narrow margin for something to just pop off the rim. Are tubeless tyres really that fussy?0
-
Ah thats fine then, my road tyres are ok until about 120 psi I think :-)0

As ever this is a forum so time for some oneupmanship =-)
A few winters ago at the end of a ride pumped my road tyres upto 100psi (outside) then brought in and left against the radiatior.
A few hours later there was a huge bang and the house shook, vase came of the mantlepiece.
No idea what had happened.
I only spotted next day when I went into the hallway and my bike was upside downa few metres away from where I left it, the tyre was shredded. I could not find any trace of the inner tube anywhere and never found it, not even a scrap!
Completely outdone by one of my friends though.
He blew one of his tubless tyres and the explosion took out a wall of his house.
(OK that needs a bit more explanation)
It was a professional greenhouse, and a JCB tyre =-)Why would I care about 150g of bike weight, I just ate 400g of cookies while reading this?0
mine should be fine, 35 psi, in the shade 8)
