underinflated tires
most likely bad shock absorbers or underinflated tires
Underinflated tires, carrying too much weight in vehicle, excessive speed, engine that needs a tuneup, brakes dragging, or partially clogged catalytic converter.
Keep tires pumped up. Tires that are underinflated have a higher rolling resistance on the road.
Yes it is
Underinflated tires wear faster on the sides than the middle.
the tyres could blow and you may lose controle of your car
before. this will prevent the tires from blowing in the case that they might be underinflated to begin with. and be wary of putting the tires to there max pressures as that is not always the pressure that performs the best under heavy weight loads.
Fuel economy is decreased by underinflated tires as well as the tire life is decreased. So you could probably see a savings of 5-10% in some cases @ 35 psi on fuel economy and save yourself the price of a set of 4 tires. Fuel economy is also affected by your driving style. Speeding, fast starts/fast stops and general nasty driving habits will kill your fuel economy really fast. Slower & steady with easier take offs from the stops will increase fuel economy.
being overly worn, overly loaded, over-inflated, OR, surprisingly, underinflated (they get very hot if they do not have much air)

Winter tires with studs are the best for driving in snow.
