Definitive Guide - Learn all about tires

Find out when it's time to change the tire and how to choose the best model for your car and your driving style.


Unlike fuels, lubricating oils and radiator water, which you change every week (depending on the car and the route, every day), tires are the type of consumables it takes to replace them. With that, when the time comes, we can be confused as to what to buy and, dangerously, when it is time to change.


Understanding tires


Tires are the only points of contact between the vehicle and the road. Only from this fact can it be inferred that appropriate tires and in good condition are extremely important for your safety and the performance of the car.


No matter how efficient, powerful or expensive the engine, the brakes and the ABS are: the three depend heavily on the tires' grip on the road. Remember that it is not the whole tire that is in contact with the tread, but four (in the case of automobiles) small rectangular areas that add up to less than thirty square centimeters.


A tire is, quite simply, a closed and flexible tubular container containing compressed air with several functions:


· support the weight of the vehicle, its passengers and its cargo

· serve as a buffer against holes and irregularities in the soil

· transmit the engine torque to the ground, pushing the car forward

· brake the car by transmitting resistance against the movement of the wheels on the ground


The first two points depend entirely on whether the tire is elastic and is filled with compressed air (that is, because the tire is inflated). The last two points, in turn, are based on the principle that the tire offers great friction with the ground . The more friction the tire offers, the less it skids - and therefore, the car doesn’t screech any tire, doesn’t slide around the curves and is able to brake properly without locking the wheel.


The modern tires are composed of about 20 different components (the "recipe" varies according to the type and brand). The main elements are:


· Inner band (or band) that shapes the tire

· Fabric meshes (usually nylon) are applied around the inner band, over the steel mesh, to give resistance

· Inflatable sides (or bubble ) serve to hold the air inside and to connect the inner band to the wheel

· The bead is a rubber and steel strap (or rather a cable) on each side at the point of contact with the wheel

· A steel mesh is applied over the inner band, which gives the tire strength and final shape

· Finally, the tread , made of softer rubber, is the point of contact with the ground.


The steel mesh (or belt) makes the tire more stable (that is, it does not deform with strokes, curbs or high-speed bends) and makes the tread more flat, which increases the area of ​​contact with the ground . Modern tires allow for a much higher average speed than those sold before the 1950s for that very reason. If you would like to learn more, please visit: milestar patagonia mt review


The Tread


The treads are different for each type of tire. There are tires with deeper grooves, for rainy days, others with “biscuits” for dirt and “off-road” roads and tires with straight grooves and a large contact area for dry asphalt.


The different treads existing in tire models can differ in two ways: in the design of the grooves - which determine whether the tire is rainy, dry, off-road or mixed - and the width of the tire. Strictly speaking, the wider, the more stable, on the other hand, the "harder" to drive.
