JARGON BUSTERS

Summer vs. All-Season:

Summer tyres like the Pilot Sport 5 use specialized compounds for maximum dry/wet precision and heat resistance above 7°C. All-Season tyres use flexible rubber for grip in both sun and snow. Due to Ireland's mild climate, most drivers prefer Summer tyres for their superior steering response and high-speed stability year-round, as extreme ice is rare.

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..
