Check your current tyre size, wheel width and offset, and the clearance around suspension and steering at full lock. 315/70 R17 is a large diameter and width, so some vehicles need suspension or arch clearance that may not be standard. If you are upsizing, confirm fitment with your vehicle handbook, the door placard, or a specialist fitter before ordering.
Match or exceed the load index specified by the vehicle manufacturer, especially if you tow, carry tools, or drive fully laden. Many 315/70 R17 options are LT-rated with higher load indexes, which can be a better choice for heavier 4x4s and pickups. If you are unsure, use the same load index as your current tyres or select a higher rating that remains approved for your vehicle.
All-terrain tyres in 315/70 R17 are typically the best balance for mixed road driving, wet grip and light-to-moderate off-road use, with lower noise than aggressive patterns. Mud-terrain tyres prioritise traction in deep mud, ruts and loose surfaces, but can be louder and less composed on tarmac. Choose based on where you drive most, then compare tread designs and reviews within this size.
Check the minimum speed rating required for your vehicle and choose a tyre that meets or exceeds it. Some 315/70 R17 all-terrain and mud-terrain options come with lower speed ratings that reflect their off-road focus, while road-oriented patterns may offer higher ratings. If you regularly do long motorway trips, prioritise a speed rating and pattern designed for stable, quieter road use.
Yes, some 315/70 R17 all-terrain tyres carry the 3PMSF marking, which indicates verified performance in snow conditions. This can be a strong choice for year-round UK use if you travel to colder regions or regularly see winter weather. Always confirm the sidewall markings and select a tread pattern that still suits your main driving surfaces.
