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.

I like that quality of wet grip while driving do not diminish during the time of use.
28.07.2024fromPhilpott
Compared with my previous Michelins, and the Pirelli summer tyres, these disappoint. No confidence in the snow and they felt unnatached in the wet.

I would like to say that these tyres saved our bacon this winter. We had lots of snow and ice over January and February this year and the tyres never lost an ounce of grip. Even when others were stuck and lost in snow drifts, the Scout got through. I was concerned about the wear of the tyres (bring softer than summet tyres but there was little wear showing on the Winter Tyres). Highly recommended for high speed road driving or off-road snowdrifts!

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.
28.05.2024fromMarcis
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.
07.04.2024fromHarry
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.

The best winter / wet and all round tyre with exceptional grip in wet conditions, quiet & safe I have ever used. Not the cheapest but worth every penny, will definitely use again without any doubt.

235/35/19/W Great tyre, only slightly noticeable from the summer tyres in terms of grip and noise, but rates 5's as a winter tyre for me.
18.06.2023fromJeremy Havard
Noisier than my Pirelli summer tyres.
08.02.2023fromMartin Green
farm use fairly mixed road/ off road
12.04.2021fromDavid Farquhar
We had 5 days of heavy snow and this proved that winter tyres work as I could keep going compared to other 4X4 dive on standard tyres. If you have to drive you are definitely safer

Excellent driving experience on these tyres. They feel safe, sturdy and solid on the road in heat, heavy rain, slippery roads due to mud, country roads, uneven and good surfaces, I have not yet tried in snow or ice. To any walkers reading this, they feel like vibram soles for my car!
07.08.2024frompeter andrews
tyres only have well below normal 6.5mm tread from new and mine were worn down to 4.1 mm tread after 400 miles plus one developed a bulge. Worst tyres ever only have perhaps 1 years life

These tyres are good for grip and average for comfort, but let down on noise levels.
