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:
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.
 
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!
 
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.
 
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.
 
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.

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

Excellent tyres and bought them to replace Nokian Winter tyres which I kept on all year round. So far I have been so impressed that we have bought 2 more sets for other vehicles.
08.07.2023 from Nick Farmer
Excellent grip on black iced roads during the winter period. Also very good grip on wet greasy roads after both light and heavy rain. Always feel in control. An excellent tyre and so far the wear is negligible.
28.05.2023 from MF
Unbelievable grip in freezing winter conditions. Good grip in all conditions. They last longer than other premium tyres which more than accounts for their relatively high price. ps 'your feedback' section, its Braking not Breaking :)
16.06.2022 from R G Hepburn
Because of the damp and at times colder weather in Scotland I prefer to use al season tyres all year round - and on my previous cars my preference was for Continental all weather of winters. Could not buy Continental's in sizes I require for my BMW 640d so chose these Vredestein Quatrac Pro after considerable research - and have not been disappointed. These are excellent tyres, grip the road well in al conditions (but no snow here yet) and are much more comfortable and quiet that previous Pirelli Z run flats - indeed so much so that a friend to whom I gave a lift recently asked it my car was electric it was so quiet. In summary - great tyres in all conditions, and it will be interesting to see what tyre wear it like over the coming years.
