Mounting and dismounting your tires

Mounting and dismounting your tires requires special skill and should be left to professionals who have the proper training and equipment. Before dismounting any tire, the valve and its mechanism have to be removed to allow the tire to completely deflate. It is very important to change the various components related to mounting new tires: wheel weights, the valve, the valve cap, and the tube (for tube-type tires). Some tires are directional and must be mounted with a certain orientation. Their external side (outside) is sometimes marked. When mounting the tire on the rim, it is very important not to exceed a pressure of 3.5 bar.
When mounting is completed, be sure that the valve caps are tightened so as to insure maximal airtightness for your new tires. As a final step, check that the wheel bolts are tightened after about 65 miles.

Balancing

In order to eliminate vibrations and imbalance in the turning mechanism, tires must be balanced each time they are changed. Balancing is necessary for both the front and rear tires of your vehicle. Be aware that your tires and the mechanical parts of your vehicle such as the suspension, the bearings or the steering are only a few examples of the components that can wear prematurely if your tires are not balanced.

Geometry

Checking the geometry may be necessary, since it can be slightly out of true, for example, following an impact against a pavement. Correct geometry increases the life of your tires, improves the road holding of your vehicle and promotes fuel economy. Poor geometry is hard to detect when driving; this is why Tires & Co recommends that the geometry is checked every time a tire is changed. Note that your vehicle's behaviour and your safety may be compromised by poor geometry.
The geometry needs adjusting if you notice:

  • abnormal wear on the inner or outer edges of the tires,
  • a tendency to pull to one side when accelerating and the other when braking,
  • a tendency to pull to the left or right when driving at a steady speed on a flat road,
  • heavy steering,
  • poor centring of the steering wheel,
  • after turning, the wheels do not quickly return to the "straight line" position.

Defective components or a strong impact (hitting the sidewalk, for example) that modifies the initial configuration will most often require adjustments in the geometry.

Storing your tires

Be careful not to store your tires in a careless manner. There are a few basic rules to follow. At the beginning of winter, when you dismount your summer tires, it is a good idea to label them with two letters (FR for front right, BL for back left, etc.) This will allow you to mount them correctly at the end of winter. Of course, the same holds true for winter tires. It is important to wash your tires and to remove pebbles stuck in the tread. tires should be stored in a cool, dry place, away from light.
