Change your tyres when you feel they are underperforming. Eg. When your car, which usually handles well in poor weather conditions, suddenly doesn’t, and when it takes longer to stop when you brake.

Most tyre manufacturers mould tread wear indicators, right into the tyres tread pattern, usually at 1.6 millimeters. When the tyre reaches this limit it must be replaced.

Check to see if your tyres are properly inflated. You will need a tyre pressure gauge to check the tyre’s pressure.

Before you begin changing tyres, check to see that your car’s jack is there, you have a properly inflated spare tyre, you have a lug wrench that properly fits your wheel, and you also have the correct lug bolts. Bring them to where you will be changing tyres.

Safely park your car, place a couple of concrete blocks beneath the tyres to ensure that it doesn’t roll or move. Remove the hubcap/plate (if they have them) and loosen the nuts prior to jacking up the car to prevent the wheels spinning on you. Turn them counterclockwise to loosen until it comes off. Then jack up the car.

Remove the old tyre. Since you have already taken out the lug nuts, pull it with your weight forward in order to prevent you from falling backward. Adjust the tyre in the threaded shafts so they fit. Then replace the lug nuts, tightening them in the proper order. Lower the jack so the tyre rests on the ground. Then replace the hubcap or plate.
