Winter tyres - for a save driving on snow and ice.
The "M + S" (or M & S, MS) marking can currently be found on winter and all season tyres. Besides this marking, a snowflake symbol can be found on some models. The M + S tyres that have the snowflake symbol meet the higher quality standards. Since 2011, winter tyres are mandatory in Ireland. Having a special blend of rubber that resists to low temperatures, these tyres are more adapted to winter conditions than the summer tyres. Therefore, the car will have a good grip even dealing with low temperatures. The optimised profile reduces the risk of hydroplaning and provides a good grip in snowy and icy conditions. The larger grooves and the additional blades improve stability when switching from snow to wet and to dry road conditions. We have winter tyres suitable for your car. Choose your favorite brand and place an order online in order to take advantage of our competitive prices!
 
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.

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’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.
