You, as a car owner, will know that one of the most important aspects of maintaining your vehicle is keeping your tyres in perfect condition. Many think that if the tyres are unused, they will remain in perfect condition forever. But that is not true because tyres do wear, irrespective of their condition, even if they are just lying in a garage or shed. Understanding this from the how and why perspective is very important for one's safety and also helps in better decisions on when to replace tyres.
