Never try to mount your own tyres. Tyre mounting is a job for people who have the proper equipment and experience. If you try to do it yourself, you run the risk of serious injury to yourself as well as possible damage to the tyre and rim.

"Regular and proper tyre rotation promotes more uniform wear for all of the tyres on a vehicle. 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 a more even and uniform treadwear pattern for all four tyres. The only exception to this would be the use of "directional" tread design tyres such as our Aquatred II or some of our Eagle line high performance tyres. These tyres would 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. Four-wheel drive vehicles may require rotation even sooner such as every 4,000 miles. Check your vehicle owner's manual for the manufacturer's rotation recommendations. If no rotation period is specified, tyres should be rotated every 6,000 to 8,000 miles. The first rotation is the most important. When tyres are rotated, inflation pressures must be adjusted to the vehicle manufacturer's recommendations. Uneven tyre wear may also be due to misalignment or mechanical problems. Many D2D retailers can provide expert diagnosis and repair."

A vehicle is said to be properly aligned when all suspension and steering components are sound and when the tyre and wheel assemblies are running straight and true. Proper alignment is necessary for even tread wear and precise steering. Uneven front- or rear-tyre wear or changes in your vehicle's handling or steering response (i.e. pulling to one side) can indicate misalignment. Many vehicles today are equipped with rear suspensions that can be adjusted for alignment. Your vehicle may need a "front-end" alignment or a "four-wheel" alignment, depending on the symptoms you are experiencing. The moderate cost of having your vehicle aligned can more than pay for itself in tyre mileage, performance and comfort. D2D retailers provide expert alignment and suspension service.

Vibration is an indication that your car has a problem that needs attention. The tyres, steering system and suspension system should be checked to help determine the possible cause and correction of the vibration. If left unattended, the vibration could cause excessive tyre and suspension wear. It could even be dangerous. D2D retailers offer expert diagnosis and repair.

Properly balanced tyres are important for driving comfort and long tyre life. Unbalanced tyres can cause vibration, resulting in driver fatigue, premature tyre wear and unnecessary wear to your vehicle's suspension. Tyres should be balanced when they are mounted on wheels for the first time or when they are remounted after repair. Tyres should be rebalanced at the first sign of vibration or "shimmy". Vibration may also be due to misalignment or mechanical problems. Many D2D retailers can provide expert diagnosis and repair.
