Key Markings and Features Explained
- OWL (Outlined White Letter): An aesthetic feature where the letters on the sidewall are outlined in white.
- M+S (Mud and Snow): All sizes carry this designation, indicating the tread pattern is capable of performing in light snow and mud conditions. The AT5 is primarily a summer/all-terrain compound.
- All-Terrain Durability: Built with a tough sidewall and robust tread pattern for resistance against cuts and chips when used off-road.
- On-Road / Off-Road Suitability Split: 60% On-Road | 40% Off-Road - This tyre provides a good balance, leaning slightly more towards confident on-road comfort and handling than a dedicated aggressive mud-terrain tyre, while still offering excellent off-road traction.
Popular Compatible Vehicles
The 15" Dunlop Grandtrek AT5 range is well-suited for a variety of traditional 4x4 vehicles and pickup trucks popular in the Irish market:
- Toyota Hilux: A common vehicle that uses several of the available 15" sizes, including the 31x10.5 R15LT.
- Land Rover Defender: Compatible with the robust 15" options.
- Jeep Wrangler: Older models often use the 235/75 R15 or 31x10.5 R15LT sizes.
- Ford Ranger: Compatible with the 235/75 R15 size.
- Mitsubishi Shogun / Pajero: Older generations of this durable 4x4 often fit these sizes.
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..
