This size is most often fitted to luxury and performance SUVs with factory 23-inch wheel options, such as certain Range Rover and Range Rover Sport specifications. Fitment can vary by model year, trim level and axle setup, so confirm against your vehicle placard or handbook before ordering.
Because 285/40 R23 is typically used on heavier SUVs, the correct load index is critical for safety, handling and MOT compliance. Match the minimum load and speed rating shown on the door jamb placard or in the handbook, then you can choose a higher rating if you want. If your vehicle specifies XL (Extra Load) or a particular marking, keep to that requirement.
Many 23-inch SUV wheel packages use a wider rear tyre, and 285/40 R23 is sometimes paired with 315/35 R23 depending on the manufacturer specification. Only do this if your vehicle is approved for staggered sizes and you keep the correct tyre on each axle. Mixing unapproved sizes can affect traction control, speedometer accuracy and drivetrain wear on AWD systems.
Availability in 285/40 R23 depends on brand and stock, but you can often find summer and all-season options, with winter choices being more limited in 23-inch sizes. If you drive year-round in mixed UK conditions, look for the 3PMSF symbol on suitable all-season or winter tyres. Always fit the same type across an axle, and ideally all four wheels, for predictable grip.
Check the tyre size printed on your current sidewall and compare it with the vehicle placard (usually on the driver door frame) or the owner handbook. Make sure the rim size is 23 inches (R23) and that the width and profile match exactly. Also confirm any special requirements, such as XL, run-flat, or specific manufacturer markings, before placing your order.
