Just been putting a pair of Aspen tyres on some stans rims. They are often a bit of a fiddle but got them seated (so I thought) in the end. After a few minutes of holding pressure I deflated, popped a good cup and a half of stans fluid through the valve and reinflated. I thought I'd put quite a bit of pressure in just to force the fluid through all the little leaks - so 4 bar and nice and tight! I turned my back to fiddle with the frame and...BOOM!
Proper echo around the valley explosion. I turned around to a scene of devastation - a sad looking tyre and jizz everywhere - it looked like I'd just given oral relief to a sperm whale! No wheel to be seen though - I eventually found it on the shed roof! Bloody glad I hadn't got it into the frame and given it a quick once around the block when it went!
3 neighbours came rushing around thinking we had had a gas explosion (which is weird as we don't have gas out in the sticks!) and were slightly bemused by the sight of dressing gown clad freak (just back from ride and could not be arsed to get dressed after shower) covered in harry monk clambering on his shed roof!
😆I eventually found it on the shed roof!
(I've been barred from google; what's 4 bar in real money ?)
You are badger and I claim my £5.
4 bar? Either your pump was lying or you looked at it wrong. Can't see tyres exploding at 60psi.
4bar = 60psi ish
Tyre did'nt explode - just came off rim in a big way.
4 bar is about 58 psi (without the aid of google) I'm sure I'll be corrected if wrong 🙂
There is a new invention that saves messing about with cups of white fluid.
Instead of the jizz, it has a "skin" of pre-solidified elasticated material that is self contained in a "tube", if you will, that holds all the air in. Maybe you want to check it out?

[/url]RTFM!C. Do not inflate tires over 40psi without a tube or the tire may blow off the rim.
I've ridden up and down stairs and off small drops to flat with my tyres at 60psi, stans rims. Crap tyres?
druidh - real men don't read instructions!
Aspens are not renown for their tubless prowess but work nicely once tamed!
effing LOL!
The mental image is hilarious 🙂
😆 like!

This had me actually properly LOL, not just metaphorically LOL

Well waste not want not I suppose. Putting it inside your tyres is quite novel, I generally find Stans Sealant works better myself...

Sorry Badger (he was actually a very nice chap, met him a couple of times) but this was the funniest recurring story on old STW by a country mile, every take on this photo was hilarious!
FWIW, back in 2005 in Morzine me and some mates got bored one evening, after I'd had to rebuild a wheel for a mate cos he was fat and bent his rim. So we took the old rim, straightend it as best as possible, fitted an old tioga DH tyre to it with an inner tube in, and pumped away... Once we'd reached 60psi we began getting a bit scared, so all donned our body armour and goggles (still inside at this point). At 80psi, I think we thought a bit better of it all, and took it outside. At 100psi, we were literally shitting ourselves at the timebomb in hand, so decided to do something to help it on its way...
So, anybody who's been to Morzine will know the bridge across the valley, with the carpark underneath... Well... Yup, we dropped it from the bridge! When it hit the floor the bang was as loud as someone blowing up a small building nearby! Needless to say, 100psi and a 100ft drop pretty much destroyed the remainder of the rim (I think it bust into about 8 or 10 separate pieces), and the tyre just shredded! Fun mind...
😯 at the mental image....then....
😆 😆
100psi 😯
Christ that was funny!

Isn't that what the kids say these days?
LOL..
Here my BOMB..

the mess cough cough...
Ended up putting well i thought 50spi to seat the tyres then
KAAABOOOOM !
I couldnt hear for 10mins as i was leant down holding on to tyre with my left had And when it blew it nearly dislocated my thumb.
Everybody in a 1mile area SHAT as it echoed 2-5 times well scary !

The tyre He He !
Found out few days later when i returned to the tyre murder the air line was faulty as prob put 90 psi before it blew .....
best quote for a whileit looked like I'd just given oral relief to a sperm whale!
It's best when it blows off the rim while you're holding it. 😆
Lost all the feeling in my fingers for a couple of hours after that one. 🙄
Real laugh out loud thread!! Thanks to th OP and everyone else. Brilliant! 😀
I blew a High-Roller off a Stan's 355 in similar circumstances
That was around 60psi too
Mine was in a confined area [shed] whilst I was holding it - there's still the staining on the roof
Wrecked the tyre and knocked the wheel way out of true
Made me laugh out loud this morning. Brilliant description. Cheers!
+1! 😀
A great way to start a Friday morning....laughing is good!. Thanks. 😆
A long time ago a mate & I made a couple of, err, thingies using big coke bottles and dry ice. middle of our garden one night.
not sure what pressure a coke bottle lets go at (they creak & groan a lot before they do), but the "pop" set off 2 car alarms at quite a distance and left a big scar in the lawn 😯
Haven't you lot learned yet :d
As soon as you approach 40PSI with a new tyre, I put the wheel round the corner of the house, place the trackpump as far away as possible and then proceed gingerly 🙂
I've not popped one of the rim yet, but as a kid I bolted a 12" wheel off a childs bike into my Raleigh Grifter. As I pedalled about on my clown bike I looked down and was amused to see a marble sized bit of inner tube sticking out of the sidewall and squeaking as it rubbed the chainstay. 10 seconds later there was a huge crack and then several echoing booms back and forth, followed by me hiding behind a car as our neighbour came rushing out of his house. (we lived behind the police station in an ex-police house, he was a copper and thought someone had fired a shotgun in the police station 😯 )
I'd pumped it up with a footpump with a broken gauge, must have been a lot of pressure but it was a huge bang for such as small tyre.
Similar to you I had my tyre explode of the rim in a confined garage, my dad also thought a gas canister had gone only to see me coated in latex and him shouting at me, luckily I couldn't hear him 🙂
Tyre also blew off the rim on the first lap of SSMM.
This was all in 2006. I've used tubes since 🙂
Always outside for me since one let go in the garage.
How can the tyre end up SO FAR away from the wheel? That's what I don't get.
I like the "round the corner" idea. I won't even switch on a light after I've changed the bulb without turning my back.
Perfect description by OP btw. 😀
Brilliant! And some badger action as well! 🙂

Do you close your eyes too?
"Damn, it's still not working!"

LOL..
Here my BOMB..
Did you get the tyre replaced under warranty? "Just riding along, etc..." 🙂
Aspens whilst great tyres are utterly cack tubeless, the side walls are way too thin.
Although that has nothing to do with your rather daft mistake.
😆 Wish you'd have got pix
I have a habit of pumping up my tyres with the wheel between my legs, i don't think i'll be doing this again
thought i was gonna do something similar yesterday, dont very often use compressors/air lines for seating tubeless tyres (usually a track pump is plenty on proper ust tyres)....i was in a bit of a rush, took it into work and was talking to someone (not concentrating) whilst i was using the airline to stick some air in......this on a brand new maxxis crossmark, i suddenly realised it had seated (although didnt ping and pop) and felt the tyre and it was incredibly massively hard.....i think if i had left it any longer the tyre would have exploded and id have wasted £40 ...just got it in time and immediately let air out, it took ages to get the excess air out to about 30psi so god knows how much id put in 😆
rode it last night pretty hard, and it was fine.....lucky escape..
although i dont get why you need to put sealant in beforehand? why not just remove the core and pour it in after its seated, then deflate, add sealant, pump back up to desired pressure?
Do you close your eyes too?"Damn, it's still not working!"
That might be why I send so much on light bulbs. 😆

One of the best eXCeption tyres when it comes to getting them on, no bother at all for me. Seems to a be a new-generation Maxxis thing, as all the tyres from last year and this go on dead easy (xmarks, aspen, monorail, rendez, ignitor).
Aspens whilst great tyres are utterly cack tubeless, the side walls are way too thin.
Never had this problem, despite most of my riding being races with plenty of pointy rocks. The eXCeption sidewalls are thin, and you will see the threads after a single muddy race, but nothing to worry about.
Great thread - oral relief to a sperm whale 😆
Hehe.. very funny thread 🙂 Only one I have is when a mate was pumping tyres up in his garage with a foot pump, we were all chatting away and hadn't noticed that the tyre wasn't seated and the tube was bulging out resulting in a fairly modest (by the above standards) blammo. We could still hear mostly, but it was a hell of a shock since we were not expecting it.
I thought I'd put quite a bit of pressure in just to force the fluid through all the little leaks
Doesn't need it. What it needs is a fair while spent being sloshed around. Slosh it around for a few mins, then ride it about, but you need to take it on an actual ride shortly afterwards otherwise it'll deflate overnight.
The bang you get from these tyres blowing off the rim is quite incredible!
I had an S-Works Sauserwind 2Bliss tyre blow off at approx 60psi - I was in my basement at the time! It was honestly the closest I can imagine to a Call of Duty style stun grenade going off in a room! My eyes were completely shaken for a good 15secs, I had no hearing bar a very, very high pitch whine for about 2mins and the shockwave raised every available particle of dust in the basement so it was pretty 'cloudy'. My poor wife was sat in the living room approx 7ft directly above the scene of the explosion so she thought the acopolypse had arrived aswell!
Laughing aside i'm very releived my hearing wasn't damaged and no debris hit me in the eyes as the tyre was shredded. I haven't inflated a mtb tyre above 40psi since... :-O
Don't they have to inflate truck tyres in cages because so many kwik fit fitters have been killed?
Popped an inner tube at 100psi on a road wheel where I had not seated the tyre properly. The tube blistered out the side and went BANG!. I wasn't even looking at it as the GF was talking to me. see, it was her fault. I'm surprised someone didn't report gunfire, it was that loud.
Complete idiot! ROFL!!!
AI!
this one's got some merit - beats soapy water, anyway;
Reminded me of inflating the pushchair tyres for the first time, never checked the psi (well would you?) happily attached to track pump in the garage, pump, pump, pump, pum..kerboom shredded tyre, ringing ears, unhappy wife.
Have never been asked to pump them up again. Result.
Had a tyre blow on my Brompton. In the middle of the night whilst we were asleep 😯 Scared the bejesus out of us!
Anyway, Air compressor & marigolds = neighbours coming round to see if we're OK after the gas explosion 😆
LOL, great thread, thanks OP et al, I'm no way going tubeless after reading this, I'll put up with the odd puncture!!!
There was an apprentice killed in my local Stapletons a few yrs back.
Apparently he sat on the (horizontal) tyre which was being inflated, when the rim let go he hit the ceiling of the warehouse.
Health and Safety executive had a field day.
hehe. reminds me when I lived in a shared house in Hackney. I'd pumped up my tyres and put them on top of the wardrobe out of the way as there were bike bits all over my bedroom floor. Massive BOOOM at about 3am launched me outta bed and all my house mates running around the house freaking out! Non-jizz though. Surprised cops didn't turn up as there had been a shooting in the pub down the road a week earlier.
A very funny post! Let's have more like it! 😆
I had one last year - 100psi road tyre, early one morning, Mrs still in bed me sorting bikes out to go out riding in the kitchen, both the cats wandering around & the tube let go.
Certainly woke me up, and the Mrs, and I didn't see the cats for a while!
Brilliant! 😆 😆
...Mrs still in bed me sorting bikes out to go out riding in the kitchen...
big kitchen!
Another lol here, been some good threads today cheers 🙂
4 bar? Either your pump was lying or you looked at it wrong. Can't see tyres exploding at 60psi.
Mine have on several occasions...with tyres that are supposedly good for 65psi.
Last one blew up in the middle of Purley and passers by thought someone had been shot. The one before blew in the back of the car and gave my poor missus a fright.
