Match the full size on your current sidewall to 285/40 R22, then confirm it against the tyre label in the door shut or your handbook. Also check whether your vehicle uses a staggered setup (different sizes front and rear) and whether any notes specify XL, run-flat, or a particular speed rating. If your current tyres are 285/40 R22, keep the same size unless your manufacturer-approved fitments list an alternative.
Choose the same load index and speed rating shown on your existing 285/40 R22 tyres or on the vehicle placard. This size is commonly fitted to heavier SUVs, so higher load ratings are frequent, and dropping to a lower rating can be unsafe and may be illegal. If you are comparing options, prioritise the correct load index first, then select a speed rating that meets or exceeds the manufacturer requirement.
Many 285/40 R22 fitments are specified as XL (extra load) to handle SUV weights and higher axle loads, so follow what your current tyres and vehicle label state. Run-flat 285/40 R22 tyres are only suitable if your car is designed for them and you are happy with the firmer ride that can come with reinforced sidewalls. Avoid mixing run-flat and non run-flat across the same axle, and keep the same construction left to right for consistent handling.
Yes, if you want more year-round flexibility, all-season 285/40 R22 tyres can be a good fit, especially for UK conditions where temperatures often drop below 7C. For regular cold-weather driving, look for an all-season option with the 3PMSF marking to improve traction in wintry conditions. If you drive mainly in warmer months or want maximum dry-road precision, a summer 285/40 R22 tyre may suit your priorities better.
A wide, low-profile 285/40 R22 tyre can highlight alignment and suspension issues, and many SUVs run negative camber that can increase inner-edge wear over time. Impacts from potholes or kerbs can also knock alignment out, which accelerates uneven wear. If you spot inside shoulder wear, book a wheel alignment check soon and replace tyres in matching pairs on the same axle to keep grip and stability consistent.
