Air Pressure: Look for your tire air pressure specification, usually written inside the door of your car. Check each tire's air pressure at least once a month. A typical tire looses 1lb of air pressure a month.

Check your tire pressure before going on a long trip.

Load carrying capacity: Make sure that you do not exceed the load capacity of your tires. The load carrying capacity is usually written at the tire's sidewall. If you are not sure, ask the store professional who sold you the tire.

Punctures: if your tire gets punctured by a nail or you run over broken glass, have the tires checked. Repairs can sometimes be made. If the puncture occurs at a place on the tire that cannot be fixed, replace the tire.

Tread depth: Check the tread depth on the tire. If it seems low or worn down, have a tire professional check it and replace if necessary.

Tire rotation: Periodic tire rotation is necessary. This is usually 6,000 miles or every 6 months.
