They are relatively tall at roughly 814 mm overall diameter, so clearance can be tighter than more common 17 inch road sizes. Check your handbook or door placard, confirm your wheel width, and consider suspension height and steering lock, especially if your vehicle is modified. If you are changing from a smaller diameter size, allow for speedometer and gearing changes and confirm fitment with a tyre professional before ordering.
Match or exceed the load index and speed rating listed on your vehicle placard, and do not downgrade from the manufacturer requirement. Many options in this size are designed for heavier 4x4 and pickup use, so higher load ratings are common and can be a good choice if you carry tools, tow, or drive fully laden. If you are unsure, choose the same or higher specification than your current tyres and keep it consistent across the axle.
Pick the pattern that matches where you actually drive. Highway terrain designs prioritise lower noise and stable on-road handling, which suits mostly tarmac mileage. All-terrain tyres are a balanced choice for pickups and SUVs that see lanes, gravel and wet grass as well as daily driving. Mud-terrain options deliver the most bite in deep mud but are usually louder and can feel less precise on the road, so they work best for regular off-road use.
It is best not to, particularly on 4x4 vehicles. Different rolling circumferences can strain driveline components and affect traction systems, and mismatched sizes can also upset handling and braking balance. Keep the same size and similar tread depth on each axle, and ideally fit a matching set of four if your vehicle runs permanent four-wheel drive.
Use the pressures on your vehicle placard as the starting point, then adjust for load and towing as the manufacturer advises. Pickups and 4x4s often require higher rear pressures when carrying weight, while lighter, unladen driving may use lower settings for comfort and even wear. After fitting, recheck pressures when the tyres are cold and monitor wear across the tread to confirm the setup is correct.
