Tyre care during summer days

Reading Time: 2 minutes

Summer is on its way and everyone is gearing up for facing the high temperatures in the coming months. Historically, in India, ambient temperatures at most of the places during summer months range from 45 to 50 degree Celsius. This high ambient temperature can create a surface temperature of tarmac road as high as 100 degree Celsius. Such high ambient and road surface temperatures can run havoc on your car tyres. Study shows that cases of tyre bursting and tyre sidewall damage increases during summer months. Hence it is extremely essential to take extra care of your car tyres during summer months.

So what if your tyre get hot!

First of all as the tyre temperature increases its adhesion with the road decreases. This can affect the steering sensitivity, reduce power and mileage of your car. If the adhesion between tyre and road decreases, all you will get is skidding and tyre slip which can prove dangerous at times. Secondly a hot tyre increases the chances of tyre bursting twin fold. When driving at high speeds occurrence of tyre bursting is life threatening. Hence it is wiser to take precautionary steps and brace the summer safely.

Check your tyre pressure

Both tyre rubber and air inside expands during the high heat conditions in daytime. Similarly when the temperature drops contraction of air and rubber happens. This expansion and contraction causes the moisture and air molecules to escape and create depletion of tyre pressure. Hence during the summer months extra care should be taken to check tyre pressure regularly. Less tyre pressure than what the manufacturer has specified is the prime reason for instances of tyre bursting and road accidents.

How to take care:

  • Make sure that you always park your car in shade. As prolonged parking in sun increases the temperature of tyre and deteriorates the rubber quality leading to cracks.
  • Occasionally you can also pour some water on the rubber to cool it down.

Nitrogen vs  Air

Generally, vehicles that are subjected to high temperatures during usage like race car, airplane, and heavy equipment tyre are filled with nitrogen. The use of nitrogen allows better control over tyre pressure as tyre temperature increases. Compressed air holds moisture and the amount of moisture may vary from tyre to tyre. During extreme usage, the amount of moisture in the tyre causes the tyre temperature to increase more rapidly, and in a non-linear way that can be unpredictable.nitrogen-or-air

With dry nitrogen, the tyres also run cooler, which is especially important in racing because the grip of race tyres is highly dependent on tyre temperature.

So if you seldom drive your cars and want to park it for long time then filling it up with Nitrogen is best. Else usage of air should suffice and yes do check tyre pressure periodically.

Tyre Valves


Ensure that tyre and valves are in good shape. Using a recognized brand tyre relieves us of the chances of faulty valves. The valves should be in proper shape and the cap that covers the valve should be fitted appropriately. The valve cap eludes the question of air leakage from the tip of the valve.

Periodically check your tyre for cracks. You can also check for unever wear or tyre bulges. In either case replacing the tyre is better option than taking risk on road.
