Some things can remain ageless. The hill that you saw while you were a kid will remain the same even after you turn ninety. Not the same thing cannot be told about things that we use in our vehicles, especially tyres.
Like any manufactured product, even tyres have a use by date and expiry date. You cannot continue to use a tyre for years together without risking your limb or life. A tyre 's fitness is very essential for avoiding accidents as it is the only thing that is in contact with the ground while you are driving.
Tyres needs to be replaced once in every three to four years to ensure safety. As you all new, tyres have treads and these treads ware out over time. These treads are essential to have sufficient road grip. They offer the much needed grip while driving on wet surfaces or on sand.
If you have a bald tyre and ignore it, it is very much similar to having smooth soles on your shoes and walking on oil. You can slip any moment and there is nothing that can save you when that happens. To avoid slippery tyres leading to a road accident always ensure you have tyres that are not worn out.
Always monitor the health of your tyres. Ensure there is sufficient air pressure in them. Also ensure all four tyres of your car have had similar ware and tear. If you have a tyre that is more worn out replace it soon as it can slip or even burst.
Having well treaded tyres will not only ensure your safety but also the safety of other road users too.
