Tires is a device that covers the rim of a wheel. Tires are an important part of the Ground Vehicles, and used to reduce vibrations caused by irregularities in the road surface, protect the wheel from wear and tear, as well as provide stability between the vehicle and the ground to improve the speed and ease of movement.
Most of the existing tires, especially those used for motor vehicles, manufactured from synthetic rubber, although it can also be used from other materials such as steel.

Tires is an object that has a shelf life, well if stored too long without being attached in the car, or if installed in a car that is very rarely used.
To know the month and year of Production Tires then we can consider 4 numbers listed to the rim near the lip (see picture).
2 points in front signifies week, 2 points behind marked the year.
For example, it says 0910 means the tire was made in week 9 of 2010
Expiration tires stored in the warehouse is 6 years old, in the sense that if we buy tires that are older than 6 years since produced the user will face a huge risk because the rubber tires are very brittle so that it becomes easier to crack and eventually break.
And for maximum safety are should buy a tire that really "Fresh from the Oven" which was only a few months since the tire was produced.
Also for tires used on cars that are very, very rarely used, replace the tires if tires are 6 years of age and should be replaced for maximum security earlier would be better, for example, was replaced in year 4.
