XL stands for Extra Load. They use a more reinforced compound to carry heavier loads, but are the same size as normal tyres. If your car had XL tyres factory fitted then you must choose XL tyres for any new ones you buy.

Winter tyres perform best in temperatures below 7°C. The rubber compound is specially designed to react better in colder temperatures which improves road grip. Some winter tyres have studs to help grip on snow and ice.

Recognising a good winter tyre is increasingly linked to the 3PMSF symbol, denoting reliability and safety in snowy conditions. The certification process involves testing in accordance with standardised regulatory methods, conducted by a certified laboratory.

M+S winter tyres, indicating suitability for mud and snow, excel in snowy or muddy road conditions compared to standard models like summer tyres. Remember that the inclusion of the M+S marking is solely determined by the manufacturer and doesn't mandate passing a certified test.
