Choosing the right tires for your car is an essential decision for your safety and comfort behind the wheel. Each type of tire is designed to respond to specific road conditions and maximize vehicle performance, which is why it's important to know the criteria you should use when selecting them.
The first aspect to consider is the season in which you intend to use the tires. Summer tires, for example, are designed to provide optimal grip and performance at higher temperatures, when the asphalt is hot.
These tires have a harder rubber compound, which allows them to maintain stability on dry and wet roads, providing excellent control under normal summer conditions. However, when temperatures drop below 7 degrees Celsius, their performance drops dramatically because the rubber becomes stiffer, which can lead to loss of grip and control.
Therefore, summer tires are only recommended for use during the warm season.

On the other hand, winter tires are made from a softer rubber compound, which allows them to remain flexible even at very low temperatures. Their tread pattern is specially designed to provide increased traction on snow, ice and wet roads, with deep grooves and multiple sipes to more effectively dissipate water and snow.
If you live in a region where winters are harsh, with abundant snowfall and low temperatures, winter tires are absolutely necessary to ensure your safety behind the wheel.
If you want to avoid changing tires twice a year, another option is all-season tires, which are a compromise solution between summer and winter tires. They are designed to provide decent performance both in summer and winter, but without excelling in either situation.
In regions where winters are mild, all-season tires can be a practical and economical choice. However, it is important to remember that, even if legal, their use in extreme snow or ice conditions is not recommended.

In addition to the season, tire size is another crucial factor in the selection process. To find the correct tire size for your car, you need to check the vehicle specifications, which are usually inscribed on the driver's side door pillar or in the owner's manual.
Tire sizes are expressed by a series of numbers and letters (e.g., 205/55 R16), each with a specific role. The first number indicates the tire width in millimeters, the second number refers to the aspect ratio between the sidewall height and the tire width, and the letter R represents radial construction. The last number indicates the size of the wheel on which the tire must be mounted.
