It is no secret that motorized rubber is considered a consumable. Expensive enough, it should be noted. We all remember from traffic rules tickets that the wear of motorcycle rubber is considered permissible up to 0.8mm. But don’t you run around with a ruler every morning? Moreover, rubber wear is different, because not only the worn out tread is the reason for the replacement of motor tires.
Consider the reasons for replacing rubber:
- Wear / abrasion
- Natural aging
- Mechanical damage
Wear / abrasion
The first and main reason why rubber is scrapped. Tire tread wear is determined visually by indicator indicators. On the tire, if you carefully examine it, there are special marks inside the tread pattern. These bumps are not a manufacturing defect, but that little thing that will tell you that it is dangerous to use rubber further. When the tread pattern is aligned with the bump, you should buy a fresh tire. It’s simple, you don’t even need a ruler.
In fact, a tire wears out the fastest at two points in its life – during break-in and after wear of the tread. The less pattern on the rubber, the faster it will deteriorate, the worse it is to keep the road and slide on wet surfaces in every possible way. In case you think that the rubber is wearing out evenly and after the critical point of 0.8 mm you still want to ride, I will disappoint you, because after this point the rubber will begin to wear off at an amazing deserter speed.
Cold rubber wears out more slowly than warm rubber. By the way, tires with lower pressure warm up faster, which means they wear out more intensively. Low pressure contributes to wear at the edges of the tire, while high pressure contributes to abrasion in the center.
What do you think, bought the rubber, put it on and it will always be as good as new? Alas, nothing lasts forever under the moon, and even rubber, treacherously aging. The first signs that rubber is about to retire are cracks. Big or small depends on storage conditions and how sad the tire is with life. Additional bells about the old age of rubber – the color from black turns into gray, loss of elasticity, hardening and roughness of the surface.
It is logical that mechanical damage refers to everything that influenced the rubber from the outside, the overwhelming majority – blows and punctures. Driving patterns, unsuccessful landings, even the influence of the suspension setting can damage the integrity of the tire.
A separate point here should be considered the burning of rubber and pellets. Since not every tire is used in light modes. Have you ever been to race tracks or demonstrations? If so, you are familiar with the smell of burnt rubber, especially if you’ve watched someone drift. From the spools, collected rubber in different parts of the tire, you can determine how the pilot drove, especially important for track racers.
All damage that the rubber receives during storage, as well as in the process of uneven loading, is placed here. It happens that bulges appear on the tire, a sure sign that it’s time to rest. Any deformation of the tire inevitably leads to a change in the distribution of force and to a displacement of the contact patch, so this rubber will have to be replaced with fresh one.
