Check the tyre size on your door placard or handbook first, then confirm your wheel is 17 inches and wide enough for 285 section tyres. Because 285/70 R17 is a taller, wider fitment than many factory sizes, also check arch clearance, steering lock and suspension components, especially if the vehicle is unmodified. If you are upsizing, be aware it can alter speedometer readings and may need declaring to your insurer.
Choose a load index that meets or exceeds the requirement stated on your vehicle placard. Many 285/70 R17 tyres are available with higher load ratings suited to pick-ups and 4x4s, which is important when towing, carrying tools or running a canopy. If you are unsure between two load options, the higher-rated tyre is usually the safer choice provided it matches your wheel and you run the correct pressures.
All-terrain 285/70 R17 tyres suit mixed driving, giving dependable grip on wet roads while still handling gravel, fields and light mud with lower noise on the motorway. Mud-terrain options prioritise bite and self-cleaning in deep mud and ruts, but they are typically louder and can feel less precise on tarmac. If most miles are on-road with occasional green lanes, all-terrain is normally the better balance.
It is best to fit the same 285/70 R17 tyre model on both wheels of an axle to keep grip, braking and handling consistent. For many 4x4 systems, running four matching tyres is strongly recommended because differences in rolling circumference can stress driveline components and confuse traction control. If you are replacing just one tyre, matching the make, model and similar tread depth is the safest approach.
Start with the manufacturer pressures on your vehicle placard, as the correct setting depends on axle load, speed and whether you are towing. With 285/70 R17, pressures may need adjusting for heavy loads to maintain stability and wear evenly. For off-road, drivers often reduce pressures to improve grip and comfort, but you should reinflate before higher speeds and avoid running so low that the tyre risks de-beading or sidewall damage.
