1. Car tire size and reference

How to read a car tire code?

There is a corresponding dimensional indication on the side of the tire, The first number marked is 185, which is the tire tread width. This is expressed in mm.

After you will see a small slash (/) followed by the number 60, it is the percentage of tire width that really determines the height of the sidewalls.

• What are the sides for?

It absorbs shocks and helps to add flexibility to the car, we will notice on sports cars, the sides are very small, it will be to better grip the road, As far as the level of comfort is concerned, we will be zero.

What is the structure of a car tire?

After you will have another little clue, it's the (R)

• What does R stand for?

You can have an R or a D, so the D you won't see much of it, that's what will determine the structure of the tire, Of course, the R is a radial tire, so it's going to be inside like I told you about it before that there were metal layers, it's a layer that intersects vertically.

How to calculate the diameter of a tire?

Then there is another small number marked 14 in the picture, this will be the tire diameter, which means 14 inches, starting at 12 inches and can go up to 22/23/24 and this will determine the size of the joint.

What speed is the tire allowed to roll?

We will see after two small things that often it is not written in large, we will find it a little further by a series of two digits 82 and a series of letters there for example and the (t).

• What does this series of 82 and t mean?

The 82 and t are a list of loads and speeds, I put you a small table that explains all the speed index of the tires according to the number and the letter and what it corresponds to up to what speed the tire is authorized to drive, it is important to respect them on the cars if you have certain indices and a certain speed to respect above all keep these same indices for the car, it is provided by the manufacturer and we are not going to put any others it could become dangerous.

Here is !! I told you about the tires to find out the dimensions, characteristics, and maintenance, we are examining the subject of seeing if they are in good condition or in poor condition.

2. What is a car tire wear indicator?

It's very simple, we have small indicators that are in the tire, these wear indicators, from the moment we reach this wear indicator, the tire will no longer be able to evacuate enough water to be safe.

How do you know if a car tire is worn on the outside?

We can see that there is a tiny bit of space before touching the wear indicators, fairly standard wear, the tire was worn by everyone in the same way we arrived at the indicators, the tire is dead, there may be several difference wear which will also join and sometimes a little diagnosis to know why the tire wears like that, the tire may wear only in the middle, the sides will be in good condition but the middle will be all smooth.

• What happened?

Quite simply, the tires were overinflated too often, which meant that the tires were in fact domed in the shape of a dome, so we only drove on the central part, there was a problem with the tire pressures. and suddenly it is worn on the central part.

The second little thing that can happen on the wear of the tires is the right side and the left side have worn out to have a central site which is still in good condition.

• What's wrong?

Exactly the opposite, we drove with underinflated tires, the tires crashed due to insufficient air pressure, and we had the two parts on the side which was in contact with the road and the central part which did not touch the road, suddenly we wore out both sides.

Then it will also have another type of wear than on one side or the right or left, when you're on a car it's where the outer side of the inner side what's going to happen it's going to be a problem of parallelism.

What does car wheel parallelism mean?

Parallelism is the alignment of the wheels of the car depending on whether the wheels are too closed or too open inwards, when you are going to drive excessively, you are driving in a straight line but the tire is misaligned.

• What comes first?

It's rubbed the interior part of the exterior part, if you have to wear it on one side or the other, you will have to think about going to the mechanic because you have a problem with parallelism, then you will wear out your tires much faster, I remind you that a problem like that is not far from costing you at least 80 dollars, there are 4 tires on the car and I'll let you do the math.

We are a little better now at how to analyze a tire, as I explained to you that the pressure was quite high, we saw that it could wear the tire in a bad way, you will have to be quite careful and vigilant on the pressure that will have to be put, because as I told you that can wear the tires on the side or on the central part.

What tire pressure is recommended for my car?

In the door, often to new drivers you will have a small label with the pressure of the tires, you look and you put in the function, you have deficiencies and graduated expressed in the bar, often we will say as a general rule on small cars we are around 2 bars of or 2.2, on a little bigger we will be around 2.4 or 2.5…

 

Here you have seen that it's very simple, there are four tires on a car, not just one wheel is checked, we always check the 4 and the little bonus we always have to think about the spare tire in the trunk, because this one if it is deflated the day you die, I can tell you that you will blame yourself for not having thought to put the pressure on this one.
