Tires

The next time you complain about poor gas mileage, start by checking your tire pressures. A semi flat tire(s) causes excessive drag on your car that slows you down, so, to go the same distance your throttle is opened more, therefore using more fuel. It's as simples as that. A tire pressure gauge is a good investment for a few dollars and checking your tire pressures regularly makes good sense, not to mention that for safety reasons too. A car with low tire pressures will actually cause the vehicle to pull and sway that could result in loss of control. Anytime you notice these symptoms start by checking the pressures. Tread wear is another important issue. Most tires have wear indicators and when the tire reaches that point, new ones are required. In addition, keep a close eye for uneven tread wear, shimmying and wobbling of the vehicle that could indicate tire separation, or that front end components are loose or a wheel alignment is required.
