Season

All season tyres - suitable for all weather conditions

All-season tyres are the perfect combination between summer and winter tyres. All-season tyres impress by their good driving qualities regardless the weather conditions and the road. The specially developed profile of all-season tyres ensures a comfortable drive throughout the whole year. All-season tyres were specifically designed for all weather conditions thus eliminating the need to change the tyres depending on the season. Discover the new alternative to summer and winter tyres: the all-season tyres. We have a wide offer from leading manufacturers at top prices! The all-season tyres designed for winter conditions need to have the "M + S" marking (or M & S, MS). Some models may also have the snowflake symbol. M + S tyres with snowflake symbol meet the higher quality standards.

Tyre size

Identify the size of your tyre

The exact dimensions of a tyre can be found on the sidewall printed mark. The graphic shows how to read properties and dimensions of the tyre:

Speed index

SPEED INDEX:

The speed index indicates the maximum speed intended for the tyre. Up to this value, the manufacturer guarantees optimum operation with the appropriate tyre pressure. The maximum speed allowed for this vehicle is given in the vehicle owner's manual; this information can be used to select the appropriate speed index for the tyre. The speed index is the last mark on the sidewall of the tyre.

Load Index

Permissible maximum axle load per tyre in kg. To be found in the registration certificate or vehicle registration document or read directly from the tyre (two-digit number). It is permitted to fit a tyre with a higher load index.

Properties

Runflat tyres

Driving safety despite puncture

Runflat tyres are puncture-resistant tyres with reinforced sidewalls. This creates the so-called run-flat property. In the event of damage, this allows the vehicle to continue driving up to a distance of approx. 100 km (and even beyond depending on the product) at a maximum speed of 80 km/h, even if the pressure has been completely lost. Run-flat tyres even prevent the tyre rubber from jumping off the rim in the event of a loss of air pressure. A flat tyre is therefore still a flat tyre, but it loses some of its drama. Note: All run-flat tyres are marked with the symbol "RSC" (Runflat System Component) and may only be fitted in vehicles with a functioning air pressure control system!

Reinforced

Tyres with increased load capacity

Reinforced tyres are designed for higher loads than normal tyres. They can be identified by the designation 'RF' (reinforced) or also 'XL' or 'Extra Load'. They are used on vans, minibuses, off-road vehicles, etc. However, their mounting alone does not automatically result in higher load capacity but also requires a correspondingly higher air pressure. Furthermore, the load capacity index specified in the vehicle documents continues to apply.

C-type tyres (commercial vehicles)

Tyres with extra high load capacity

The "C" in the term C tyres stands for "commercial". These tyres are specially designed for commercial vehicles. These can be, for example, lighter trucks, delivery vans, flatbed trucks or panel vans. In other words: vehicles that have to move higher loads at a comparatively lower speed. The multi-ply reinforced C tyres are therefore even more load-bearing than reinforced tyres.

Rim Protection

Seal Layer

Mobility-optimised tyres

A tyre with a sealing layer on the opposite side of the tyre tread. In the event of a puncture (e.g. by a nail), this layer blocks any loss of air, even if the foreign body causing the puncture is still in the tyre. It is not necessary to stop or change the tyres immediately at the roadside.

Noise Reduction

Mobility-optimised tyres

Electric-optimised tyres

Tyres optimised for electric vehicles.

Tyre developed for electric vehicles. These tyres can also be used without hesitation on vehicles with other drive systems.
