Draw out your tires as long as possible.
Fitting tires is a job for professionals
This delicate operation consists of assembling a unit comprising a wheel, a tire and a valve, not forgetting the air for inflation. Any operation achieved to a professional guarantees scrupulous compliance with the instructions specified by tire manufacturers, vehicule manufacturers and legislation. He will be able to detect any anomalies liable to affect your safety.
Proper wheel alignment is vital to your safety!
It's difficult to tell if your wheels and axles are correctly aligned while driving. But if your vehicle's suspension geometry is incorrect, its handling may be altered and your safety compromised. If your tire has come into contact with a solid object, such as a kerb or pothole, or you have noticed uneven wear on your tires, please go to a tire specialist to have it thoroughly inspected. It's important to ensure correct alignment to get the best road handling, to protect your tires from irregular and/or rapid wear and to save fuel.
Maintain balance!
A well balanced tire, with an even distribution of weight, rotates on its axle without causing any vibrations. For perfect balancing, weights are placed at certain points around the rim. This can only be carried out by specialists, as it requires specific measuring equipment. Well-balanced tires make for more comfortable driving, longer tire life and less premature mechanical wear.
Perfect sealing
To ensure tire sealing, the rim must not be distorted or rusted. When fitting, the beads must be properly positioned on the rim. The valve and its cap must be changed every time it is fitted.
Puncture
Whether a small perforation or a large puncture resulting in a significant loss in pressure, your tire must be inspected by a qualified tire expert. Only a professional will be able to ascertain whether the inner casing has been damaged, making the tire impossible to repair.
Safety guidelines in the event of a puncture
Always consider your safety and that of your passengers. If you can, stop your vehicle in a safe place, away from the traffic.
Apply your handbrake.
Switch off the engine and put the car into gear.
Switch on your warning lights.
Put on your reflective safety vest.
Place your warning triangle at the required distance behind your car.
Start changing the wheel:
• Wedge one of the wheels.
• Place the jack in the planned position, near to the punctured tire.
• Loosen the nuts, but do not remove them.
• Raise the car until the wheel clears the ground.
• Remove the nuts and put them in a clean place.
• Remove the punctured wheel.
• Place the spare wheel on the hub.
• Tighten the nuts slightly.
• Lower the car and remove the jack.
• Tighten the nuts with the wrench.
• Put the tools and punctured tire in the trunk.
Take care when rejoining the flow of traffic. Remember to switch off your warning lights. Stop at the first service station to check the air pressure of the spare tire. Tighten the nuts as much as you can. Insufficiently tightened nuts can damage the brake discs or distort the balance of the wheels
