Frequently Asked Questions
Regular and proper tyre rotation promotes uniform wear. All-season tyres should be rotated in a “modified X” pattern, meaning only the tyres being moved to the drive axle are crossed to the opposite side of the vehicle. The remaining two tyres are moved from the drive axle to the free rolling axle, remaining on the same side of the vehicle. This method of rotation helps promote even and uniform treadwear pattern for all four tyres.
The only exception to this would be the use of “directional” tyres. These tyres should remain on the same side of the vehicle and be rotated straight forward and straight back. If you have a four-wheel drive vehicle, we recommend crossing both pairs of tyres to their new axle positions.
We recommend tyre rotation at least every 6,000 miles. It is a good idea to rotate four-wheel drive vehicles every 4,000 miles. Check your vehicle owner’s manual for the manufacturer’s rotation recommendations. The first rotation is the most important. When tyres are rotated, inflation pressures must be adjusted to the vehicle manufacturer’s recommendations.
When radial tyres are used with bias tyres on the same car, the radials must always be placed on the rear axle. Never mix radial and bias-ply tyres on the same axle. When you select a pair of replacement tyres in the same size and construction as those on the car, we recommend you put them on the rear axle. A single new tyre should be paired on the rear axle with the tyre having the most tread depth of the other three tyres.
Tyres of different size designations, constructions and wear may affect vehicle handling and stability. For best all-around performance, it is recommended that all tyres are of the same size, construction (radial, non-radial) and speed rating. If tyres of different speed ratings are mounted on a vehicle, the same size, type and speed ratings need to be placed on the same axle. The vehicle speed should not exceed the acceptable limits of the lowest speed rating of the tyres. Never mix radial and bias-ply tyres on the same axle.
Asymmetrical tyres are designed to improve handling and reduce noise. These tyres can rotate in either direction with the correct side facing out as indicated on the sidewall. If installed with the wrong side facing out, the tyre will not provide optimum performance. However, no damage or premature wear to the tyre will result. Simply have it dismounted and reinstalled correctly.
Tyres with a “directional” tread design are intended to roll and perform in a specific direction. The sidewall has arrows indicating the rolling direction of the tyre. If installed in the wrong direction, the tyre will not provide optimum performance. However, no damage or premature wear to the tyre will result. The tyre should be dismounted and remounted to roll in the proper direction.
My unidirectional tyres were mounted incorrectly and are rotating in the wrong direction. What should I do?
“Unidirectional” tyres are designed to operate on a specific side of the vehicle. If installed in the wrong position, the tyre will not provide optimum performance. However, no damage or premature wear to the tyre will result. The tyre should be dismounted and remounted to roll in the proper direction on the proper side of the vehicle.
A trained tyre professional will have to determine if your flat tyre is safe to repair. When a tyre loses its air pressure, it must be removed from the wheel for a complete internal inspection. Tyres driven a short distance while flat can be damaged beyond repair. Most punctures smaller than ¼” and confined to the tread area can be repaired by trained personnel using industry-approved methods. Tyres with punctures on the sidewall or tyres worn below 1/16″ can not be repaired.
Always use the air pressure recommended by the vehicle manufacturer. You can find the proper tyre inflation level in your owner’s manual, posted on the edge of the driver’s door, on a door post or on the inside of the glove box door. Remember to check your air pressure when the tyres are COLD, and use a good quality tyre gauge to ensure accuracy. It’s natural for radial tyres to have a slight bulge in the sidewall at their proper inflation level. Make sure to adjust inflation every few weeks, before a long road trip or when traveling with a heavy load. Also, remember to check your spare tyre.
Absolutely! To increase the life of your tyres, avoid speeding. Excessive heat is generated while driving at high speeds, increasing the rate of wear, and reducing the tyre’s durability. Avoid fast turns on curves, fast starts and panic stops. Also, try not to ride on the edge of the pavement, or drive over curbs, chuck-holes and other road hazards.
