Check the tyre size on the sidewall of your current tyres, then cross-check the vehicle’s door jamb sticker or owner’s handbook for the approved sizes. If your car lists multiple wheel and tyre combinations, make sure 275/45 R22 matches the wheel diameter (22) and the axle fitment shown by the manufacturer. If you are unsure, use your registration lookup and compare the results with the markings on the car before ordering.
Choose a load index and speed rating that meets or exceeds the figures listed on your vehicle placard or handbook, as larger SUVs can require higher load ratings in this size. Many 275/45 R22 options are available with XL (extra load) construction, which may be required depending on your vehicle specification. If front and rear ratings differ, match each axle to the manufacturer recommendation to maintain handling and stability.
It depends on whether your vehicle has 275/45 R22 as an approved alternative size. The 45 profile increases overall diameter compared with a 40 profile, which can affect speedometer accuracy, wheel arch clearance, and how the ABS and traction systems behave. Confirm approval in your handbook or with the manufacturer, and consider notifying your insurer if you change to a non-listed size.
Yes, several manufacturers offer all-season tyres in 275/45 R22, designed for year-round use in the UK with improved cold and wet performance versus summer tyres. For the best winter capability, look for the 3PMSF symbol (three-peak mountain snowflake), not just M+S. If you regularly drive in very low temperatures or snow, a dedicated winter tyre in the same size may still be the better choice.
Replacing all four at once gives the most consistent grip and handling, especially on heavier SUVs. If you replace only two, fit the new pair on the same axle and keep the remaining tyres close in tread depth to avoid imbalance. For many AWD systems, keeping tread depths similar across all four tyres can help prevent driveline strain, so check your vehicle guidance before mixing tread depths.
