With a ‘space saver’ wheel fitted, you should not exceed about 80 km/h (50 mph), and you must follow any lower limit printed on the tyre or shown in the car’s handbook.

Key speed rule

  • Most motoring and safety sources state that temporary space saver tyres are designed for a maximum of 80 km/h or 50 mph.
  • Many space saver wheels carry a clear sticker or sidewall marking with the limit (often “MAX 80 km/h” or “MAX 50 MPH”), and that marking takes priority if it is lower.

Why the limit is lower

  • Space saver wheels are narrower, smaller and often run at much higher pressure, which affects handling and braking and makes the tyre heat up more quickly at speed.
  • They are designed only as a temporary emergency measure so you can drive carefully to a tyre shop, not for normal motorway cruising or long distances.

Safe driving tips on a space saver

  • Keep below 80 km/h (50 mph), slow down even more in wet or icy conditions, and avoid sudden steering or hard braking.
  • Replace or repair the full-size tyre as soon as possible and switch back; prolonged use of a space saver increases wear and the risk of failure.

In practice: Treat a space saver as “limp-home only”: light traffic, short distance, and no more than 80 km/h (50 mph), or any lower figure printed on the wheel.
