Special Feature Markings

XL (Extra Load) / RF (Reinforced):

Meaning: The tyre has a stronger, reinforced internal structure to safely carry heavier loads. Why it matters: Essential for heavy vehicles, SUVs, and Electric Vehicles (EVs) which are heavier due to batteries.

FR or FSL (Rim Protector):

Meaning: A protective ridge of rubber running around the lower sidewall near the wheel rim. Why it matters: Helps protect your expensive alloy wheels from scuffs and minor damage caused by accidentally brushing against a kerb.

EV Ready:

Meaning: A general design principle for this tyre range (not a specific code) focusing on low rolling resistance to save battery life, and special noise-reducing design for quieter EV cabins.

Summer vs. All-Season Tyres in Ireland

Summer tyres are Ireland's standard, providing peak efficiency and grip above 7°C. Due to the mild climate and rare snowfall, many motorists use them year-round. However, summer rubber hardens in the cold, increasing braking distances on freezing roads.

All-season tyres offer a "fit-and-forget" alternative. Their flexible compounds provide reliable grip in both sun and slush, ensuring safety during sudden cold snaps. They deliver consistent year-round performance without the cost or 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..
