Summer Tyres & The Irish Climate
Summer tyres use specialized hard compounds for maximum dry/wet precision above 7°C. In Ireland’s mild climate, enthusiasts prefer the Dunlop Sport Maxx RT 2 for its uncompromising high-speed stability and shorter braking distances, though All-Season options remain popular for those seeking year-round "peace of mind."
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..
