Tyre sizes can vary by year and trim level, so the most accurate method is to use the registration search. If you are searching by size, copy the full marking from the tyre sidewall (for example 225/70 R16) and make sure the load index and speed rating match your vehicle requirements.

Many RX 300 fitments require higher load ratings than standard car tyres. Choosing tyres designed for SUV use can improve stability, braking and wear under heavier weight. Always follow the load index and speed rating shown for your vehicle when selecting options.

It is generally best to fit matching tyres across each axle for consistent handling and braking. If your RX 300 is all-wheel drive, keeping tyre sizes and tread depths closely matched can help reduce strain on the drivetrain, so avoid mixing unevenly worn tyres.

After selecting your tyres, choose a nearby garage and book an appointment time at checkout. The tyres are delivered directly to the fitter for your visit, where they are installed and balanced. Some garages may charge separately for extras like disposal of old tyres, so check the fitting details shown.

All-season tyres can suit UK conditions well if you want one set for year-round driving, offering better cold and wet performance than summer tyres. For frequent winter travel in colder regions, consider winter tyres with the 3PMSF marking and switch seasonally for the best grip.
