Can Your Car Fail Its MOT with a Factory Spare Wheel Fitted?

The MOT (Ministry of Transport) test is a mandatory examination for vehicles in the UK to ensure they meet road safety and environmental standards. Conducted annually for vehicles over three years old, it checks various components including brakes, lights, seatbelts, and tyres. Failing an MOT test means the vehicle is deemed unroadworthy until repairs are made.

What is a Factory Spare Wheel?

A factory spare wheel, often called a “space saver” or "temporary use" spare, is a spare tyre provided by the vehicle manufacturer. It is typically smaller, lighter, and designed for short-term use until the original tyre is repaired or replaced.

MOT Regulations and Spare Wheels

According to UK MOT regulations, a spare wheel is not an item that is checked during the test. The condition of the spare wheel, whether it is present or not, does not influence the MOT result directly. However, the situation can become nuanced if the spare wheel is being used on the vehicle at the time of the test.

Using a Spare Wheel During an MOT Test

When a factory spare wheel is fitted to the vehicle during an MOT test, the spare wheel becomes subject to the normal tyre checks. These checks include criteria such as tread depth, condition (no bulges, cuts, or other damage), and conformity to tyre specifications for the vehicle. The spare wheel, if used as a regular tyre during the test, must meet the necessary standards.

Temporary spare wheels, marked as restricted in terms of speed, load, or distance, may not conform to the requirements for a standard wheel. This non-conformity could potentially lead to a failure or advisory note stating that the tyre does not meet the necessary standards for regular use.

Recommendations

To avoid any issues during the MOT test, it is recommended to replace the temporary spare wheel with a regular wheel that matches the specifications outlined by the vehicle manufacturer before attending the test. Ensuring all tyres are in good condition and suitable for continuous use will help in the successful passing of the MOT test.

Conclusion

While a vehicle cannot fail its MOT simply for having a spare wheel, using a factory spare as a main wheel during the test can result in complications. Ensuring that all tyres used during the test meet the safety and specification standards is crucial for passing. Proper preparation and attention to detail are key for a smooth MOT process.
