Tires can come off the rim (a situation often called "de-beading") for several reasons:
Low tire pressure: If the air pressure is too low, the tire bead may not stay tightly sealed against the rim, making it easier for the tire to slip off during cornering or impact.
Improper mounting: If the tire is not correctly installed or the bead is not properly seated on the rim during installation, it can lead to de-beading.
Damaged or bent rim: A bent or cracked rim may not hold the bead properly, especially under stress or load, leading to the tire coming off.
Sudden impact or force: Hitting a pothole, curb, or large obstacle at speed can force the tire off the rim.
Overloading: Carrying loads beyond the tire or vehicle's capacity can put excessive pressure on the sidewalls and bead area, increasing the risk of separation.
Old or worn tires: Aging or heavily worn tires may lose structural integrity, making the bead weaker and more likely to unseat.
