Tire marking decoding for passenger cars, labeling wheels, how to choose the right tires on the disks

Ideally, the best option for the acquisition of the wheels is to acquire the wheels in the kit, i.e. Tires to buy with disks. But this option is not always obtained, or due to the lack of finance, or do not like discs or tires. If you bought a tire without disks, how to choose the wheels to your tires try to find out in this article.

Marking of passenger car tires, which denote letters and numbers on tires and disks

The main characteristic of the wheel is its diameter, and the wheel diameter is indicated by the letter "D".

The diameter of the wheel installed on the car must correspond to the diameter of the recommended car manufacturer.

If the car has wheels not relevant recommendations, the characteristics of the fuel consumption are changed, the wheel parts can occur, and this worsens the safety of motion.

Disks Also have the main parameter in the form of a diameter, and the diameter of the disks is indicated by the letters "DD".

Disks have a width, the width is considered the distance from one edge of the rim to the other and is indicated by the letters "WD", the size is usually indicated in inches.

Rubber except diameter has its own height of the profile and denotes "DT". If the rubber has a small height of the profile, the wear of such rubber occurs very quickly, the car with such rubber can only move on the perfect road surface.

For our roads, it is better not to acquire low-profile tires, otherwise the load on the suspension of the car will increase and the disk deformation is possible.

In addition to the bad characteristics of the operational, low-profile tires is also very noisy.

Car tires have both width, it is indicated by "WT".

In urban conditions and on slippery roads it is better to use narrow rubber.

Wide tires well established itself on a dry track, during a braking machine on a wide rubber has a short braking path.

Marking of discs on passenger cars

Marking disc It is knocked out anywhere disk, with the exception of the inner surface, which is addressed to the rim.

The first marking element is indicated by the digits of the width of the disk in inches.

Latin letters are written behind the numbers, they can be both in combination jj, jk or simply Latin letters P, D, B, K, J.

Latin letters indicate the profile contour form, the height of the shelves, the angle of their inclination, the radius of the roundabout.

If after the letters stands the symbol "x", then the disk is a one-piece structure, and if instead there is a sign "-", then the disk is a collapsible structure.

Then there is a digit that indicates the disk diameter, the Hampov index is behind the diameter.

Hampov index - there is a value that denotes the annular protrusions along the cloud and they serve to fix the tubeless tires during the turn. Simple Hamp denote the letter "H".

If the hump flat is denoted by "fh", the asymmetrical Hamp is indicated by "AH".

There are disk designs without boumps.

Then indicates the magnitude of the location of the mounting holes, for example "6x98".

With this scenario, the disk has 6 mounting holes, and the circle diameter of the centers of the mounting holes (RSD) is 98 mm.

The number of holes can be from 4 to 6, and the diameter of the circumference of the centers of the mounting holes can be from 98 to 137.9 mm.

Selecting the tires under the disks, it is necessary to pay special attention to the location of the mounting holes.

After the parameters of the fasteners, the distance between the plane of the disk mounting to the hub and its vertical axis is indicated in the marking.

This departure is denoted by the letters "ET", going on these letters of the figure and there is a departure in millimeters.

Disk departure can be 0, positive or negative. The suspension and the steering mechanism are adjusted from departure.

The latter digit in the disc marking indicates the diameter of the planting hole.

The diameter of the seating opening of passenger cars is between 50 to 70 millimeters.

Frequently in marking indicate the maximum load, the date of manufacture and production method.

Discs can be forged, licensed and stamped.

Light car tire marking table

If you have discs, and you need to choose rubber, you need to decrypt rubber marking, since all the necessary information is laid in the marking.

Marking is located on the side surface of the tire.

In addition to the information, information about the country producer, models, etc. are located on the head surface of the rubber.

The information that is contained in the code is called a standard size.

The first number of the code is the width of the tire in millimeters, the size is indicated by the sidewall.

The following digit means height, in a percentage of width, i.e. If there is a cipher 225/50, then the height is 50% of the first digit, i.e. 112.5 mm.

After the figures, there is usually an alphabetic designation, this letter contains information about the design of Cord.

If it is the letter "R", then the rubber has a radial cord.

The subsequent character of the digit contains information about the size of the rim, the size is indicated in inches.

Here in this labeling there is important information necessary when a selection of tires in size.

How to choose rubber correctly

To choose the rubber correctly a very important point, because the safety of driving the car depends on it.

If you purchased a used car, you can contact the car on the car and most likely, you will find the necessary information there.

Well, there are no books, open the glove box and if there is a sign, draw the necessary information from it.

If there is no such sign, refer to the specialized tire sales sites, fill in the sign information on your machine and you will give you the necessary information about the rubber you need.

Matching tires and disks - how to achieve this

Axiom of tire matching disks, how to achieve this compliance?

Professionals advise comply with simple rules:

-Shirin rubber profile should be larger than the size of the disk by 25-30%;

- Fall and disk must match their central holes, if the holes do not match, special installation rings will come to the rescue. The outer diameter of the setting ring is equal to the disc hole, and the inner diameter is equal to the size of the hub;

-Prings must strictly correspond to the diameter of the circles of the centers of the discs of the discs. Let's say that there is no more than 2 mm, if there is such a break, then special bolts with eccentrics are used in the attachment;

- The best option when everything coincides with 100%.

To correctly pick up the tires to the disks, you can use the special tire selection table to disks. This table indicates sizes and tire matching to disks.
