How are tires described?

Tires are ones of the most essential elements of the car and driving to our destination safely is hugely dependant on them. A good selection of tires goes beyond choosing a specific type and size, but also means picking the ones that will perform well on certain surfaces. We need to bear in mind that the year’s season plays a huge part in selection – our drive’s comfort, traction, convenience and safety – it all depends on proper tires. That is why it is extremely helpful, not only for the sake of casual drivers who should have at least some knowledge related to the tires they need but also for the employees of vulcanization stores and workshops, to mark the tires’ sidewalls with special symbols. Thanks to these codes it is much easier to decide which model is which and decode its properties. What can we learn from tire’s code? Virtually everything that is to be learned.

First of all, it is the tire maker, a made responsible for the tire design that wants to mark its own product. That is how the made is advertized among the drivers – a quick glance and they know which company produced it. Thanks to the tire code we also get to know its type and what kind of tread it has – a keen eye lets us know with what type of tire we are dealing and whether it is snow or all-terrain tire. We may guess the type without such close look most of the time, however, such a method will not work in every case. Tire code will help us realize tire’s cross-section width given in millimeters, percentage proportion of tire’s height and width together with rim’s inch diameter. Radial tire bears a special marking too. However, there is more we can decode from these markings – tire’s heaviness indicator, its speed rating and whether the tire comes with or without an inner tube. On every tire there is also information when it was made. Sometimes we will learn what its wear indicator shows or how long our all-season tires or snow tires will last in winter time. Tires of increased weight come with additional markings. It may sound challenging, but we are completely able to deal with such on our own. Let us take 210/55 R 16 90 H as an example. It means as follows – its width in millimeters, proportion of its height and width, radial base structure, rim’s inch diameter, bearing capacity shown in kilos and speed rating. However, these are not the only information we can get – as an example of DOT DM 6P 38T (0606) shows. It stands for the following – United States Department’s of Transportation acquiescence, a code describing tire’s maker, factory in which it was made, its size or type (DM 6P 38T) and its production date in brackets. Should we find M+S code on the tire then it means it is snow tire, on the other hand words like tubetype or tubeless indicate whether the tire comes with or respectively without an inner tube.


Types of tires

In nearly every vehicle there are different parts of equipment needed, different is also selection of gear depending on the year’s season and conditions in which such gear will be used. That is the way tires are selected and the method of division is a type of tread.

The first type is snow tiree – they are extremely important to give us proper traction during the winter. In their case the tread is indented, thanks to which it gives us a great traction both on wet and slippery road. The important issue is the structure of snow tire – it will be made of a rubbery mixture that has to be soft when the temperature goes down. As a consequence this type of tire is useless in summer, because in high temperature the mixture becomes too soft and wears out quickly. We substitute it with summer tires that are sometimes called All Season tires that have good traction both on dry and wet surfaces and it is made possible by the tread’s carvings. In these kinds of tires there is a very good system of water outlet – it happens during the drive and even fast drives too – broad channels led around the perimeter together with broad side channels are doing a great job during the rain. Thanks to such types of tires the comfort of the drive is leveled up. Helpful is also the fact that the tread pads are pretty big. Regarding the rubbery mixture that the summer tire is made of, it is tough in hot temperature but in the winter its toughness becomes a problem and it is impossible to have a comfortable drive with it. Another type are the all-terrain tires – seem to be quite distinctive, with big tread pads being something really different than in comparison with those of casual tires. These type of tires are much more resilient to getting flat, have thicker tread and tire’s sides and creating them in form of deep and broad channels makes them connect shape with strength. It is a relocation of pretty big driveline moments in difficult terrain conditions for which these tires are made. Yet another type of tire is mud and snow tire. They are much more soft than the all-terrain tires, but compensate this fact with much better traction on slippery surface in comparison to the all-terrain ones. These are the models pretty similar to the all-terrain tire, but the tread pads are even more adjusted to keeping better traction.

Tire change becomes extremely important – especially during the change of seasons – to avoid queues we can decide to have the tires changed even earlier. Besides, freezes and other hostile weather conditions may come earlier than we think so it is better safe than sorry. Correctly chosen tires may turn out to save our life more than once, so we should make sure to have them and have them changed when it will help us control our vehicle better. Of course every vehicle has its own types, not to mention their sizes – their selection will not be difficult though – however should we encounter a problem then we will be advised to consult a professional or pay a visit to a vulcanizer. Thanks to that we have a guarantee of a well-selected service and as a consequence greater safety while on the road.
