Match the figures shown on your driver-door tyre placard or in the handbook, as SUVs using this size often require higher load ratings. If you pick a lower load index or speed rating than specified, it can affect safety, insurance and MOT compliance. Use the filters to select your exact load and speed, then compare like-for-like tyres.
Many 235/50 R21 fitments are specified as XL to support heavier vehicles and higher axle loads, but it depends on the manufacturer requirement for your model and trim. Check the sidewall of your current tyre for XL or Reinforced, and confirm the load index on the placard. If XL is specified, choose an XL tyre with the same or higher load index.
Yes, provided you keep the correct load index and speed rating, and all four tyres are the same type on AWD vehicles where the manufacturer requires it. For year-round use, look for all-season tyres with the 3PMSF symbol if you want stronger cold-weather capability. Expect all-season options in this size to prioritise wet grip and temperature range over peak summer handling.
They can be, as long as the load rating meets the higher weight of many EVs and the tyre is designed to handle instant torque. When comparing products, check for EV-focused versions, higher load indices, and features like low rolling resistance or acoustic foam if cabin noise is a priority. Always follow the vehicle maker specification for load, speed and tyre type.
You can, but it is best to keep tread depths closely matched on the same axle, and many AWD systems are sensitive to differences across all four tyres. If the other tyre on the axle is significantly more worn, replacing the pair is usually the safer choice for consistent grip and braking. Before ordering, measure tread depth and check whether your vehicle handbook recommends replacing tyres in pairs or sets.
