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.

Good grip, solid performance on rough country roads, and smooth enough on A roads, balanced breaking and no vehicle shudder
05.02.2025 from Dean
I've done around 8500 miles so far in mostly poor weather , very good grip in all winter conditions and mild conditions. Good all rounder.
28.05.2024 from Marcis
Good grip on wet and dry roads. Reasonable grip on snow and icy roads. Noisy on dry roads. Fuel consumption has increased. All in all decent tyres.
07.04.2024 from Harry
Incredibly capable tyre for all conditions, but my experience on the roads in West Yorkshire will probably dictate that I don't purchase these tyres again as they are too soft on the sidewall, they do need some sort of protective band. The roads a terrible around Haworth for potholes, and in this case I could not dodge one and it has ripped the sidewall and damaged the rim, rendering the tyre scrap.

These are an excellent alternative to the Michelin Alpin A3 which I have historically run. They were cracking before wearing out. I needed something that would stick the power of the vehicle and be controllable. These fit the bill admirably.

I am a professional driver in my working environment (emergency services). These tires are rubbish. Any speeds over 50kph in wet weather will cause them to hydroplane.

Tires performed better then expected. Very comfortable and quiet ride. Great dry and wet road driving

Not a sport tyre. Very disappointment.

Steady, now I'm over 70, with the occasional speed burst for fun. Usually stick to speed limits now.

Quiet & grips well. Gouges very easily on curbs when parking
