Rotating your tires

Front and back tires usually wear differently, especially on front wheel drive vehicles. They’ll last longer if you rotate them.

  • Rotate your tires according to the vehicle manufacturer’s recommendation, found in the owner’s manual. Or talk to your tire professional to find out how – and how often – the tires on your vehicle should be rotated. Common practice is to rotate tires approximately every 10,000 km.
     
  • When mounting the wheels on your vehicle, make sure the wheel nuts are tightened to the manufacturer’s specifications. The correct wheel nut tightness can be found in your owner’s manual.

Replacing tires

As a tire wears, traction is reduced. A tire must be replaced when the tread has worn even with the tread wear indicator. The tread wear indicator is a small raised bar that runs across the grooves of the tire tread, marking the minimum allowable tread depth. Normally, there are six tread wear indicators spaced evenly around the tire. For optimum traction in wet or snow conditions, replace your tires before they reach the minimum tread depth.

  • New tires should be the same size, and have the same load capacity and speed rating as the original tires, which will have this information printed on them. The size also appears on the tire information label, which is usually located on the driver’s door or inside the driver’s door frame.
     
  • To ensure proper vehicle handling, install the same type of tire on all four wheels.
     
  • Getting the best value and performance from new tires depends on clearly understanding your vehicle and your own driving needs and being able to communicate your needs to a tire professional who can assist with the final decision. Automotive publications and manufacturers’ Web sites provide consumer information that may be useful. You can also visit the Buying Tires section of the Be Tire Smart Web site at www.betiresmart.ca.

Register your tires! When you buy new tires, ask your dealer for a copy of the tire registration form. Fill it out and send it in. If there is a recall, the manufacturer will be able to contact you directly.
