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.

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

Original equipment quality: optimum adjustment to the vehicle
Tyres with a special OEM marking on the sidewall, e.g. "MO" for Mercedes-Benz, were developed in cooperation with a specific car manufacturer and the tyre industry. These tyres have been homologated by the vehicle manufacturer and are a perfect match for a specific model. They have been specially designed to highlight or further improve the performance characteristics of the car in question, thus representing the culmination of a state-of-the-art fine-tuning process that perfectly complements the latest technological developments in the automotive industry. Tyres with manufacturer's markings can of course also be used on other vehicles.

The driving experience with these tyres is very good with good stability of the vehicle. I have not had any issues with driving on these tyres and find that the build of the tyre is substantial and suitable for my vehicle.

Good tyres but not as good as the Michelin pilot sport 4. Will be going back to the sports.
04.12.2019fromAli
I am a High mileage driver covering all roads day and night. This is a premium summer tyre made for dry grip and wet braking. Out of a budget , midrange and premium I&rsquo;ve noted , the cheapest gives me around 6000 miles. The mid ranges cover around 12000 miles and premiums last around 18000 miles. In terms of grip it always has to be premium. These are also much quieter than budget tyres. I&rsquo;ve covered 25000 miles of hard driving with these tyres and they still have around 3mm left. This is the second summer I&rsquo;ve purchased these tyres. Good on price as well as grip

A sure grip in all weather / road conditions
30.04.2021fromPaul
Just avoid, unless you live in Finland or something. Driving in WET and Dry, just terrible grip and I have a 4x4 Subaru with LSD. It&#39;s shocking really. Unless you drive really slow, it&#39;s OK then, but come roundabout they just don&#39;t grip doesn&#39;t matter wet or dry. Good in snow, but it should be at least good in wet as well and OK in dry, but It&#39;s crap in both wet and dry, so not good for me, will not buy again.
05.06.2019fromAsh
I didn&#39;t get these on until Feb/Mar when worst of the weather had passed. Driven on main roads &amp; motorways at temps between 3&deg;c and 16&deg;c in mixed weather without problems. Obviously they were less responsive at the higher temps but never felt dangerous. No sign of wear at all. Dry road grip when accelerating lost traction a bit too easily but cornering was predictable.
