Front tyres wear faster on FWDs and with understeer, more worn tires will be more permeable to air. In fact unless you like doing heaps of fishys, doughys and burnouts, your tyres will wear faster than the front in any well balanced car.
Normally from overloading the vehicle or running the tire low of air, or both.
LOW AIR PRESSURE IN YOUR TIRES loose accessory belts such as alternator can squeal
Means the air pressure in your tires is low
Put air in the tires!
low tires cause drag and it takes more to push these tires down the road. most bikes run about 40psi.
Low pressure.
It inflates the tires/tyres when they have low pressure in them
It means that you need to check the air in your tires.
Running the tires low of air pressure or too much air pressure. Suspension out of alignment. Hard fast driving with sudden stops, hard acceleration, and driving on a curvy road at a high rate of speed.
Low speeds indicate shifted belts in the tires. If it also pulls to one side, try rotating that side front to back.
Wal-Mart has some of the cheapest tires that you could find. They always strive to keep their prices as low as they can for their valued customers. They have them starting at $59.00.
Energy or matter move from high potential to low potential. This case the high pressure mean there is more air in its' volume so it expand toward those spot with lesser air than its' volume. For example, low pressure front may due to the heat cause air volume to expand. The air then move up due to its' buoyancy and that cause the low pressure. The colder and denser air is then draft toward those low pressure front.
