TIRE INFO

AIR PRESSURE

A vehicles tire pressure should be set to the manufacturers recommended specification. This can be typically found on a placard attached to the driver side door jam.

Incorrectly inflated tires can cause irregular tire wear, decreased handling and performance and greater gas consumption.

Remember to check your pressures monthly!

WHEEL BALANCING

Every time a tire is mounted to a rim it must be balanced. Wheel balancing compensates for the weight difference between the tire and rim. Wheels that are out of balance create a vibration at highway speeds. Wheels that are no longer balanced properly can cause irregular wear on the tire thereby reducing the longevity of the tire. It also causes unnecessary stress on the suspension and front-end parts.

If you feel this type of vibration it is important to get your wheels re-balanced!

ROAD FORCE BALANCING

A perfectly balanced tire can still vibrate due to Force Variation.

Wheel Force Variation is most frequently due to wheel runout or uneven tread or sidewall stiffness in the tire. Runout is when a tire or rim is out of round when rolling; frequent causes are a bent rim or uneven tire wear.

Uneven tread or sidewall stiffness can be found in new or worn tires. Tires by design are never uniformly flexible throughout nor are they perfectly round. And no two tires are exactly alike in these characteristics.

Wheel force variation is corrected through the use of a special balancer that matches the high point or stiff spot of the tire to the lowest spot on the rim.

Please note in some cases a wheel is so out of round it must be replaced or a tire with excessive force variation is defective.

ALIGNMENT

Your vehicle does not have to pull to one side for your wheels to be out of alignment. Improper alignment will degrade the handling of your vehicle and cause the tire to wear out prematurely eg.tread shaved on inside edge.

You should get an alignment everytime you buy new tires!

WHAT SIZE IS MY TIRE?

Tire Sidewall

Tire size and type can be found on the sidewall of your tire.

  • 1. Tire width.
  • 2. Aspect ratio (height).
  • 3. Inside diameter.
  • 4. Load index.
  • 5. Speed rating.

When asking for a quote this information is required.

TIRE ROTATION

Tire Rotation

Tire rotations are one of the most important things you can do to maximize the life of your tires and consequently the size of your wallet!

During a rotation your tires get inspected for any irregular wear and your air pressures are checked as well.

The tires on your vehicle should be rotated every 10,000 to 12,000 kilometers.

At J&D Tire when you buy four tires you receive free rotations for the lifetime of the purchased tires! (passsenger rated tires only)

TIRE REPAIR

Your tire should always be demounted from the wheel and inspected for damage or unsafe conditions, which might make the tire non-repairable.

The tire should then be repaired by removing the object that caused the damage, then drilling out the injury to remove all damage to the tire.

Based on the size of the injury, your tire repair specialist will then determine how the tire should be repaired. Typically, a "nail hole" injury is any injury 1/4" (6mm) or smaller in passenger tires. Injuries larger than 1/4" (6mm) are considered to be "section repairs" on passenger tires. Injuries larger than 3/8" (9mm) are considered section repairs on light truck and truck tires.

A proper tire repair procedure uses a vulcanizing rubber stem to fill the tire injury and the proper sized tire repair patch to reinforce the inner liner of the tire.

Do not have your tire repaired with any plug or string/rope product from the outside only. These tire repair products do not meet Industry Standards and are not considered to be permanent repairs. These repairs also void most tire manufacturers warranties.
