The next letter stands for the construction of the tire, where the R in the example stands for Radial. When the aspect ratio is bigger, then the sidewall is also bigger. In the example above, this means the tire’s height is about 65% of the width. The next two numbers after the slash mark refer to the aspect ratio or the ratio of the tire cross-section’s height to the width. These tires are neither hard nor soft, they are just right in the middle.
This means you will not be able to speed up on highways without taking the risk of slipping or even turning over. They also have less contact surface on roads that are paved. The disadvantage is that these large tread blocks make the rollers noisier than other tires. They also come equipped with bigger tread block patterns, which means they have enough grip while driving on gravel, dirt, and loose sand. They have sidewalls that are quite stiff, which allow these vehicles to carry heavy loads and go over rocks and whatever obstacles lie in rough roads. Light trucks and SUVs would find this kind of tires most suitable. Unfortunately, this kind of tires has a noisy downside. These are the ones with the snowflake symbol, and many of them have embedded metal studs to give the tires a better grip when the roads are covered in snow. However, snowy and icy roads require bigger block patterns that offer the best contact with the road’s surface.

If you are driving in snowy and muddy conditions, then M&S tires are the ones you should install in your car. There are two kinds of winter tire compounds, suitable for different conditions. This is the reason why there are winter tires, exactly for the purpose of allowing you to drive safely in slippery, icy roads. In fact, having the wrong tires can definitely cause an accident.
Tyre aspect ratio calculator Patch#
This is the reason why it comes with a contact patch wider than an all-season tire.ĭifficult is an understatement when describing driving in snowy conditions. During the rainy season, tires should quickly heat up in order to ensure the contact with the road’s surface. The major difference between wet weather tires and summer ones is that they have more siping that work on channeling the water away from the contact patch of the tire. Wet weather tires are not that different from summer tires, in the sense that they are also made of softer rubber compounds as opposed to all-season ones. If you do not have particularly special requirements, this kind of tire is perfect for you. Moreover, it has the right balance between a silent drive and still performing very well when there are heavy downpour and wet road conditions. However, this is not necessary for the day-to-day driver, which is why 9 out of 10 motorists use this type of tires all the time. These tires are made of rubber compounds that are harder than the summer tires, which means it has worse performance and grip. They have the right combination of grip, performance, safety in wet weather conditions, durability, and acceptable noise. Cars that come out of the assembly line and most likely what you end up buying comes with all-around or all-season tires.
