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 best winter / wet and all round tyre with exceptional grip in wet conditions, quiet &amp; 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&#39;s as a winter tyre for me.

Noisier than my Pirelli summer tyres.

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

I like that quality of wet grip while driving do not diminish during the time of use.
28.07.2024 from Philpott
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!

14.06.2020 from johan silkenas
Smooth and absolutely lovely on snow, sensational grip. Great feel of safety on wet roads. Used to drive with Pirelli Sottozero 3 winter-tyres which are great too however these GoodYear UltraGrip Performance + winter-tyres are a new level of tyres.
28.05.2020 from Will
I drive an automatic which is terrible for grip with only the slightest snowfall, and I&rsquo;m very cautious in sub zero icy weather. However with the UltraGrip Performance + tyres I was full of confidence every time I drove in sub zero weather conditions. Breaking distances were further than summer tyres, as expected, but nothing to worry about. Car performance was very good and fuel consumption while motorway cruising was better than summer tyres! There was no snowfall this year so I cannot comment.
