Peeling out until you have no thread, driving over thorns, nails, sharp rocks, or other sharp objects. Overinflation.
Most BMX tires are loose on the rim and have to be straightened as you blow them up. I blow up very slowly and rotate and straighten the tire as it gets inflated more.
There are several things that can cause a tire to blow. -you can run over a piece of road debris or a sharp rock that'll cut the tire bad enough to blow -sheer mileage can cause the tire to wear through to the casing, at which point it'll have lost a lot of strength and may blow at any moment. - poor wheel alignment can cause the tire to wear through to the casing, at which point it'll have lost a lot of strength and may blow at any moment - low pressure can cause the tire to heat up, which makes the rubber softer and the tire weaker which can cause it to blow - heavy load can cause the tire to heat up, which makes the rubber softer and the tire weaker which can cause it to blow overinflation can cause it to blow just like when a balloon pops.
a pump
Eventually blow out
Then you take it to a tire shop for possible repair.
Highly unlikely
Inaccurate pressure can cause poor mileage, uneven tire wear, or a tire blow-out. To prevent these events from happening it is important to maintain proper tire pressure.
It really depends on a lot of factors. Once I had a 35psi tire "blow up" on 45 psi ... and it was the spare. (It didn't blow up - it sort of quietly disintegrated over a matter of about 10 minutes.) usually a tire is OK at twice its rated pressure - but remember, fast running and/or low pressure can cause quite a rise in the pressure of a tire. I've measured 75 in a 45 psi tire after a long run.
Severe overinflation can blow a tire off the rim, but unless that happens underinflation is a far more reason for tire slippage.
It can be very dangerous especially at high speed. Many accidents happen due to this very thing. Blow a tire at high speed and you may very well loose control of the vehicle.
Blow up a balloon or inflate a tire.
Deterioration of the rubber, overpressurizing, curb pinch.
