Spare tyres are an essential component of vehicle safety. They offer a lifeline during unexpected incidents or emergencies on the road. Many drivers rely on them as a short-term solution. However, only a few understand their limitations and proper maintenance.
Unlike regular ones, they are designed for temporary use and are subject to specific lifespan and safety guidelines. After a certain time, you have to visit the best tyre shop and replace the spare tyres. It ensures, they perform effectively when needed.
In this article, we will explore the lifespan of spare tyres, signs of replacement, and essential safety guidelines.
Understanding the Lifespan of Spare Tyres
The lifespan of a spare tyre is influenced by factors such as its design, storage conditions, and usage. They are designed for temporary use and have a recommended lifespan of 6 to 10 years, even if unused. If they surpass their lifespan, they should be replaced, regardless of their physical appearance.
Repeated or extended use can accelerate wear and tear. Proper storage is also crucial in extending their lifespan. For example, tyres stored in extreme temperatures or under the vehicle without protection degrade faster. Regular inspections and maintenance ensure that they remain functional and safe when needed.
Signs of Replacement
Visible Cracks and Dry Rot
Over time, the rubber in spare tyres can deteriorate due to environmental elements. This leads to visible cracks on the surface or dry rot, which weakens the structure. If you notice these signs during an inspection, it’s time to replace the spare, even if it hasn’t been used.
Low or Uneven Tread Depth
Spare tyres that have been used may show signs of tread wear. If the tread depth falls below the legal limit or appears uneven, the tyre will not provide adequate traction, especially in wet or slippery conditions. A worn-out tread is a clear indicator of replacement.
Bulges or Blisters
Bulges or blisters on the sidewalls indicate internal damage. It is often caused by pressure changes or impact. These weak points can lead to blowouts, making the spare unsafe for use. Immediate replacement is necessary if such issues are detected.
Air Pressure Issues
If the spare tyre cannot maintain proper air pressure or frequently loses air, it may have an internal puncture or damage to the valve. Driving on an underinflated tyre can result in further damage.
If you notice any of these signs, immediately opt for a replacement. Make sure you opt for branded options, such as Yokohama tires, as they are affordable and offer better performance.
Safety Guidelines for Spare Tyres
- Check pressure regularly to ensure proper inflation according to the manufacturer’s recommended PSI level for optimal performance.
- Avoid exceeding 50 mph and 70 miles on spare tyres to prevent damage or failure.
- Regularly check for cracks, bulges, or punctures that could compromise safety.
- Adhere to the recommended lifespan and replace them after that, even if they are unused.
Spare tyres are essential for your safety while driving. Therefore, you should not overlook them. Inspect them regularly and replace them when needed.
