Here is some useful information that the experts at Centre Techno Pneu think you should know. You can find out more by calling Centre Techno Pneu.

My Needs

Have your treads worn even with the tread-wear indicator? If so, it is time to change your tires. If you want to make a wise choice, you should ask yourself a few questions first. What type of tire is suitable for your car? Do you want high-performance tires, tires that grip the road, economical tires, tires for wet or snow-covered roads? Do you drive a sports car, a sedan, a pickup, etc.?

Tread-wear Indicator

The tread-wear indicator is a small raised bar that runs across the grooves of the tire, marking the minimum allowable tread depth.

Tires Sizes

Once you have found the answers to your questions, you must choose the right size tires. To determine the proper size, refer to your vehicle’s owner’s manual or the car manufacturer’s label, which is usually stuck on the frame of the driver’s door.

Information Marked on the Tire

The sidewall of the tire carries useful information in the form of letters and numbers. If you wish to understand the information, you must learn how to decode it. Here’s an example to help you understand what the code means:

P185/70R14 88S

P = Passenger vehicle

185 = Width of the tire in millimetres

70 = Height / width ratio, or in other words, the ratio between the height of the tire’s sidewall and the width of the tire.

R = Radial construction

14 = Diameter of the wheel in inches

88 = Load index

S = Speed rating

Speed Rating

L'indice de vitesse est représenté par une lettre entre A et Z. La lettre indique la capacité maximale du pneu lorsque la capacité de charge et le gonflage sont adéquats.

Speed In KM/H






Load Index

The load index is a number between 0 and 279. The number corresponds to the vehicle’s load-carrying capacity.

The DOT marking is another code that is indicated on the sidewall. This marking indicates that the tire complies with the US Department of Transportation’s Tire Safety Standards for motor vehicles. This code often includes the name of the tire manufacturer, the factory, the manufacturing date and the brand.

Safety Tips

You must follow certain rules in order to ensure that your vehicle’s tires are safe:

Mounting and Demounting

To avoid damage to your tires or your vehicle, trust the mounting and demounting of your tires to a professional. Your tires will last longer if they are rotated regularly.

Air Pressure

Check your tire pressure every month and before a long trip. The tire should be cold, or in other words, your vehicle should not have been driven more than five kilometres during the preceding three hours. Use a pressure gauge to check the pressure of each tire. The pressure gauges that are sold in stores are generally more reliable than the built-in gauges on air pumps at gas stations.

Load-Carrying Capacity

To avoid a flat tire, do not exceed the load carrying capacity indicated on the sidewall of your tires.


When purchasing tires, look for the best quality at a competitive price. The experts at Centre Techno Pneu can help you with your purchase. They will always provide you with excellent service.
