A guy at a tyre fitter fitted a tyre to a whel for me today. As it reached the point that the air was going in to the tyre, after only about 20 seconds, the tyre made a loud bang noise. The guy stopped immeidately and said "they all do that".

I thought that they make that noise when the beading snaps. If that is the case, he has damaged my tyre. But I don't know enough to know if he is right or not. The guy seemed a bit nervous and embarassed about it. Maybe it was just his demeanour, who knows.

Is it a bad thing for a tyre to make a bang when it is being fitted? It doesn't show any external evidence of damage...

Few years ago I was fitting some Pirelli slicks. Normally (other makes) seat at under/around 40psi.
These ones went up to over 60 and were showing no signs of seating.
I was a bit concerned and called the supplier who said keep going!
I had the wheel outside behind a fire door while inflating it from inside. It went with one hell of a bang, no damage done!

A dipstick that I knew once decided that inflating the tractor tyre to over 38psi would finally make it seat on the bead. It was something like a 20.8 x 38.

He made the stupid mistake of sitting on it while he blew it up. When it "blew up" (and I mean went BANG) he hit the roof and was dead instantly or very soon after.

Had he followed the "rules", when it got to 20psi and hadn't seated, he should have stopped, brokn the rest of the bead again, applied more soap and tried again. And put it in a cage. Not sat on it.

They're never run at more than 16psi, typically 8-10psi.

If you think your car tyre went bang, try a 386/65R22.5 Michelin on an Alcoa alloy rim! damn!

tyres do degrade but the 'soon after' reference makes me think he means the thin fellow who should have stuck to oil measuring.

Service manager of the dealership I worked in had to go to the funeral of one of his nephews.
Again, tyre center fitting truck tyres, young lad left to do it himself. When the tyre went it took the lad into the rafters.

A few years ago I was watching a tyre fitter fitting a Dunlop 900X20 truck tyre which blew up at around 65 psi (normal presure 95 psi). It split round the wall about 2ft long. He had it in a safety cage, but the blast still embedded the grit off the floor into his shins and caused me to st myself.

We had a 295/80r22.5 blow, split the tyrewall and moved a 1200l oil tank 8 inches across the floor, the tank was 6 feet away from the tyre when it "popped", nearly crapped myself!!

Crazy mega low profile hard side wall tyres are the worst for this and sometimes difficult to get off. Never seen seen run flats done but bet they are hard work.
