How suitable is all season tires in comparision to other tires.

How suitable is all season tires in comparision to other tires.

For people who avoid taking the burden of changing the vehicle’s tires twice a year, for them  all weather tires appears to be a logical compromise. These tires are designed to work throughout the year but in reality all season tire offers ninety percent of the wet and dry performance delivered by a summer tire and ninety percent of the performance exhibited by a winter tire on the snow.


Tires do have a grade mentioned on them which is called uniform tire quality grading (UTQG). This rating tells you few things about tires for all-season such as:


•           Tread Wear: The higher the number, the longer you can expect the tread to last. You can expect these tires with a larger number of tread to sustain for longer time than the one with a smaller number of tread.


•           Traction: This rating is based on these tire's ability to stop a car on wet concrete and asphalt.


•           Temperature: It is a measure of how well the tire dissipates heat and how well it handles the buildup of heat. The temperature grade applies to a properly inflated tire that is not overloaded. Under inflation, overloading or excessive speed can lead to more heat buildup. Excessive heat buildup can cause these tires to wear out faster, or could even lead to tire failure.


All of the tire components of all weather tires - bead, tire body, belts, sidewalls and tread are assembled in the process of building tire. All these components are placed in the correct place and form the tire into a shape and size as per the specified. Tires meant to give high performance usually have a low aspect ratio than other types of tires. The reason being is tires with a less aspect ratio offers enhanced lateral stability. When your vehicle goes around a turn then lateral forces are produced and the tire has to prevent these forces. These tires have shorter and stiff sidewalls so that they can resist cornering forces in best way.

all weather tiresare also known as "wet optimised" winter tires. These modern tires have tread patterns and sipes as of winter tires, but use less winter optimal compounds to enhance performance in dry weather.  Following table shows the handling speed of winter, all season and summer tyres under different winter weather conditions:


Handling (kph)            Winter All Season       Summer


Snow                                58.9            55.3        0

Wet                                  72.8            70.6     73.7

Dry                                   114.9          114.7   116.7



Under dry road surfaces, the braking distance with the winter tires and tires for all-season is just 0.3 meters apart. On changing the road surface to wet, winter tire halts just two meters behind the summer tire and the tires for all-season takes 5.2 more meters to come to a standstill state.
