Summer tyres are most common in Ireland, offering peak fuel efficiency mileage and grip when temperatures stay above 7°C. However, they are not the official standard for winter safety. Motorists must show caution in cold conditions; below 7°C, summer rubber hardens, significantly compromising grip and wet braking performance on cold, saturated Irish roads.
All-Season tyres are the superior "fit-and-forget" solution for Ireland's wet, temperate climate. Specifically engineered to remain flexible in the cold, they provide shorter stopping distances on near-freezing, rain-soaked surfaces and carry the 3PMSF certification for frost and light snow. They offer total year-round peace of mind without the hassle of seasonal swaps.
Load Rating: Maximum Weight Capacity Explained
The load index is a numerical code representing the maximum weight in kgs that a single tyre can safely carry. To ensure safety, the combined capacity of all four tyres must exceed the vehicle’s total weight when fully loaded.
Speed Rating: Maximum Velocity Explained
Represented by a letter, the speed rating indicates the maximum kph a tyre can maintain over a prolonged period. Higher speed ratings are engineered to handle the heat and stresses generated at faster speeds more effectively.
Quick Reference Guide
- Check your requirements: You can find the specific requirements for your vehicle on the tyre information plate (usually located on the driver-side door pillar) or in the owner's manual.
- Replacement rule: It is vital never to fit a tyre with a lower load index or speed rating than those recommended by the manufacturer.
- Common Ratings: Standard ratings include T (190 kph), H (210 kph), and V (240 kph). You can view a full conversion table below..
