What Happens to Tyres During Extreme Cold Weather?

 

Winters are quite harsh on cars; one area that is regularly overlooked is the tyres. While most folks consider adding antifreeze or de-icing the windscreen, the rubber connecting the car to the road is also affected by several problems when it gets cold. To ensure drivers stay safe and avoid unexpected breakdowns during the colder months, it is important to understand these changes.

Why Does Cold Weather Affect Tyres?

Rubber is a substance which is affected by temperature changes. As the temperature decreases, the chemicals in the tyre start to become harder. This may not sound significant, but it affects the tyre's performance on the road. A harder tyre cannot grip the road surface as well, particularly on wet or icy roads. That's why cars can feel wobbly on frosty mornings, even though there's no apparent damage to the vehicle.

Reduced Grip and Handling

As stated above, cold temperatures cause rubber to become stiffer. This stiffness decreases the ability of the tyre to bend and adapt to small bumps and imperfections in the road. The stiffer the material, the less contact it will have with the road surface, leading to less grip. This is especially obvious when braking, cornering or driving on wet roads, as stopping distances may be much longer in the cold.

The Risk of Cracking

Tyres can also suffer from small cracks due to very cold weather, particularly if they are already worn or old. Typically, cracks first appear in the sidewalls and may become more noticeable over time if they are not addressed. The cracks reduce the strength of the tyre, and can make it more prone to a sudden puncture or blowout. Drivers must visually check tyres before long trips, especially during the winter season.

Why Tread Depth Matters More in Winter?

More drivers than they think are affected by tread depth. Deeper tread channels water and slush away from the tyre's surface, helping to maintain grip. As tread wears down, this ability is diminished, resulting in a higher risk of skidding or skidding on water. During the winter months, tread depth is one of the most important factors, as worn tread can be particularly dangerous in snowy or icy conditions.

Should Drivers Consider Winter Tyres?

Some drivers opt for winter tyres in regions with regularly very cold weather conditions. They are made of a different rubber material that remains soft at extremely cold temperatures. They are also designed with deeper tread patterns to enhance grip in snowy and icy conditions. Although not all drivers will require winter tyres, it is worth considering for anyone who commonly drives in extreme winter weather.

Simple Ways to Look After Tyres in Winter

There are a few easy steps drivers can take to protect their tyres during cold weather:

• Air pressure decreases at a faster rate in cold air, so check tyre pressure weekly.
• Check tread depth for safety and legality.
• Inspect the sidewalls for any cracks or bulges, particularly if motorists have driven over rough roads.
• Avoid harsh braking or acceleration on icy roads, as this puts extra strain on tyres.
• Store an extra tyre, inflator or repair kit in the car, in case of winter breakdowns.

Carrying out a few simple checks can make a difference when your car is in frosty or snowy conditions.

When to Seek Professional Help

When a driver observes that their tyres are vibrating, wearing out unevenly or that a tyre has lost pressure, it is best to get expert advice on their vehicle. Garages can be the first to spot damage that most people might miss. Anyone considering buying tyres Hamilton must visit local garages that perform a full winter check, checking the tyre pressure, tread depth and general tyre condition.

Common Myths About Tyres in Cold Weather

Drivers frequently make a few mistakes in winter. Another misconception is that the car doesn't need to be fitted with tyres that are in good condition, as the four-wheel drive system will take care of that. Four-wheel drive does help with acceleration, but not stopping or cornering and worn or under-inflated tyres remain a hazard. One of the myths is that the tyres should be checked only when it gets icy outside. The truth is that tyres deflate and become stiffer as soon as the temperatures begin to fall, sometimes weeks before frost does. Knowing about these misconceptions will encourage drivers to take the appropriate precautions early in the season, instead of waiting until it gets to a dangerous level.

Conclusion

Tyres are under extra stress during cold weather, and many people likely wouldn't notice. These changes can impact the safety of a car's handling on the road, from a loss of air pressure to harder rubber and an increased chance of cracking. Regardless of how cold it gets, drivers can take a few simple steps in winter to ensure tyres are in proper condition and minimise the risk of an accident by checking them regularly.
