Why tyres need replacing (at +7°C)
Winter tyres are not recommended to be used at temperature above +7°C, and summer tyres – at temperature below +7°C as the rubber composition for summer and winter tyres differs in formulation suitable for specific temperature conditions. A summer tyre stiffens in winter, and a winter tyre softens in summer, which adversely affects performance.
Safe operation of tyres
Choosing a suitable tyre enables to:
Adherence to simple rules when using tyres also increases their operational life.
It is important to check tyre pressure with a precise tyre gauge at least once a month and prior to long-distance drives. A proper tyre pressure helps optimize tyre performance, saves fuel, improves handling and prevents road accidents.
Tyres should be balanced when being mounted, as badly balanced wheels may produce vibrations when driving. This may result in early uneven tyre wear and undesired damage of your vehicle suspension.
What is a tyre wear indicator and where to find it
A tread wear indicator (TWI) is a very important element that helps identify when your tyres need changing. Tread wear indicators are located in relation to a TWI sign on the shoulder of the tyre. They indicate that your tyre is wearing down and needs replacing (not earlier for economic reasons and not later for safety reasons). Tyres should be changed when the tread pattern is worn down to the height of the tread wear indicator (1.6mm).
How to identify the tyre manufacture date and wether it matters
Yes, it does. A tyre is supposed to preserve its technical specifications for 5 years from the manufacturing date given use and storage requirements are met. Manufacturers all over the world mark the manufacture date on the lateral side of the tyre.
Keep your tyres away from direct sunlight, moisture, heating sources, flammable products, strong acids and alkali, etc.
Tyres with rims should be stored lying down, and tyres not fitted on rims – vertically. This will help them stay in good condition for next seasons.
Even the world's best tyre fails to protect you from all surprises of a summer and winter weather. Abiding by driving regulations and having mutual respect for other road users is an essential constituent for the overall road safety.
