Confirm 255/70 R16 on the tyre sidewall you are replacing, then check the door-jamb placard or handbook for the approved size, load index and speed rating. This size is common on 4x4s, but some trims use alternatives, so matching the placard avoids clearance issues and speedometer changes.
Pick a 255/70 R16 tyre with a load index that meets or exceeds the figure listed on your vehicle placard. If you regularly carry heavy loads, tow, or drive a full-time 4WD, choosing a higher load rating or an LT-spec option (where approved) can improve stability and durability.
For mainly tarmac driving, a highway-terrain 255/70 R16 tyre is usually quieter and can return better fuel economy. If you split time between roads and tracks, an all-terrain 255/70 R16 tyre offers stronger shoulders and more open tread for grip on mud, gravel and wet grass, with a small trade-off in noise.
It is best to fit matching 255/70 R16 tyres across the same axle, and ideally all four on many 4x4 systems. Different tread patterns and wear levels can change rolling circumference, which may affect handling and, on some drivetrains, place extra strain on differentials.
Use the pressures shown on your vehicle placard, as the correct PSI for 255/70 R16 depends on vehicle weight, load and whether you are towing. Check pressures when tyres are cold, and recheck after fitting new tyres to keep wear even and maintain predictable braking and steering.
