Zorluk: OrtaTyre Safety and Requirements

After experiencing a puncture, you fit a temporary space-saver spare wheel to your car. Which restriction must you follow while driving with this wheel fitted?

  1. A
    Reduce the tyre pressure below standard recommendations to compensate for the smaller contact patch.
  2. Drive at a maximum speed of 50 mph50\text{ mph} (80 km/h80\text{ km/h}) and replace it with a standard tyre as soon as possible.Cevap
  3. C
    Maintain normal driving speeds up to 70 mph70\text{ mph} (112 km/h112\text{ km/h}) as long as the tread depth exceeds 1.6 mm1.6\text{ mm}.
  4. D
    Drive at a maximum speed of 30 mph30\text{ mph} (48 km/h48\text{ km/h}) and avoid using dual carriageways or motorways.

Cevap

You must not exceed a speed of 50 mph50\text{ mph} (80 km/h80\text{ km/h}) and should have the tyre replaced with a standard road tyre as soon as possible.
Space-saver spare tyres are smaller and narrower than standard vehicle tyres. They are intended solely for emergency use to allow you to reach a tyre specialist or garage. Operating them above 50 mph50\text{ mph} (80 km/h80\text{ km/h}) or over extended distances compromises braking stability and cornering grip.

Adım Adım Çözüm

1
Identify the type of replacement wheel fitted to the vehicle.
The vehicle is fitted with a temporary space-saver spare wheel.
Space-saver wheels have distinct mechanical characteristics, smaller dimensions, and narrower tread compared to standard road wheels.
2
Apply manufacturer safety specifications and UK regulatory guidance for space-saver wheels.
The maximum permissible speed is 50 mph50\text{ mph} (80 km/h80\text{ km/h}), and usage is strictly temporary.
The altered dimensions adversely affect vehicle stability, handling, and braking performance under extreme conditions.
