Front wheel goes at motorway speed, it's not going to be pretty.
For you, I'd recommend popping a wheelie and riding one wheel to a stand still. Someone of your 1337 status would have no trouble reacting to a blow out with a wheelie  ____________________ Ted : "Maybe he's agoraphobic."

I a tyre is in a position to have a blow out there is nothing you can do to avoid. No tyre foam or puncture sealant is going to do anything.
If rear one goes you'll usually stay on, if in a very rare case a front gives out you'll be be coming off. ____________________ Nobby the Bastard: How yo tell the difference between the actual japanese and her just screaming because she's had live fish stuck up her arse?

i had the rear blow out on the SP-1 at about 60mph after the front wheel flicked up a piece of slate and wedged it at a perfect angle under the rear tyre which left a 4 inch gash across it. It sounded like a firework going off and i thought i'd blown the engine or something.
Wasnt much drama at all to be honest, nowhere near as bad as you think it would be. I wouldnt fancy my chances if the front went at anything over 30mph though ____________________ 04 NSR 125(sold) ---- 03 CBR 600rr(sold) ----90 pan euro ST1100 ' ' ----02 CG 125

I crashed going round a corner when my tyre went from 40psi to 0 in a second Valve actually gave up, considered a blow out? Either way I got away with a scuff to my trousers at 60mph  |

Valve failures seem to be a common problem recently, there was one in the BMW club mag last month (OK I'm an old fart, live with it, I do), he was lucky, it happen just as he parked up at the end of a ride. Dunno if it's bad installation technique (bike wheels are difficult using 'normal' car type tools, I've been a tyre fitter), or in his case one of those 'nut' type caps that's been over-stressing the rubber to brass bond, but I now replace my bike (and caravan) valves with bolt in metal bodied jobbies, even nippers 125 scooters got them!

Alright smart arses, it went flat pretty fucking quickly, better?
It was a bit sketchy and had it been the front I would've gone down, but it's alot more controllable at the rear. |

Had a front tyre blow out and produce a massive hole/tear about the size of a five pound note while doing 80mph on the autoroute.
Result was that the steering got very heavy and the handlebars shook.
Quite easily managed to slow down and pull over though, wasn't even a brown trousers moment. Fortunately the I was going in a straight line at the time.
I imagine a blowout from the sidewall would be different. ____________________ Motorcycle headlight bulbs and HIDs

Thinking about it, 20 years ago I had a rear wheel go at 80 plus on a fully loaded R80RTIC (ex-job bike) two up, a bit like riding on ice, on the M62 at 8am on a bank holiday Monday. The RAC sent a man at ~9:30 with a van who took the wheel and returned it 'repaired' around 11:30. Refitted it and got as far as Holmes Chapel when it went down again on a roundabout. Two hours plus in a car dealers show room drinking coffee and this spec. lifter appears, put the bike across the speccys and back to Manchester to have it put on the oldest beaver-tail you've ever seen. Then wait for a driver to turn in for an hour or so, onto the M6 going North to go and refuel before finally heading home to Hampshire, M6 was bad, M5 was stuffed, so we navigated him across country through the Cotswolds and down through Salisbury plain, saving atleast 6 hours going by the traffic reports, finally off-loaded at 2am. Put the spare from my R60/6 in it for the last 1/2 mile home as he couldn't get near our place, numpty cagers blocking the road as usual, stripped the rim to find the tube pinched, arsehole tyre fitter had caused the second flat...
ALL the recent rear flats have been tubeless tyres with screws and other 'stuff' stuck in the tyre, so I reckon most if not all punctures are probably caused by lack of road cleaning, J5 M27 is a prime example, and builders etc not giving a dam about loosing stuff on the road these days. Avoiding filtering on areas where cages don't sweep helps! |

1. Yes.
2. Possibly with tubes, modern radials handle like shit anyway if underinflated.
3. Hummm, solid objects, like timber and other stuff dropped on the road? Or 'bumping' over a kerb which fucks the casing internally and usually invisibly until it fails.
4. Only fools who shouldn't be on a bike, or the roads in general, dodgy tyre dealers may play a role though.
"So the post solution is prevention." Agreed.
"Check your tyre pressures and adjust to the load and road conditions" Difficult, most bigger bikes now state 36f/42r, loaded or unloaded, no matter what, but knowing and adjusting where relevant should be part of daily checks.
Cheapo tyres, no such thing for a lot of us, running big brand tyre's is often cheaper anyway due to better compounds and better wear rates! |

I ride bigger bikes. I increase tyre pressure with a pillion or luggage, as well as the preload.
I also tend to ride about 0.1/0.2 bar higher than the manual for front/rear as it greatly increases tyre life. The manual was designed for all around general conditions for an average person. High speed tar you can inflate higher higher, dirt lower, and body weights differ. I'm stocky and musucular and heavier than the averager person the manual is written for, so I ride with a bit more pressure.
On gravel, you can under inflate, but then you are vulnerable to pinch outs if an impact. So I dont underinflate much and rather choose to ride a bit slower.
I carry a compressor on long trips so i can adjust my tyre pressures according to conditions. ____________________ 2011 KTM 990 Dakar

Sorry, what?
I don't think an insurance company would refuse a payout for 2psi over stock.
I only check mine when things start to feel a bit odd.  |
