Marking
All disk drives must be marked on the inside. The marking indicates the week and year of manufacture, the melting number, the permissible load, the size. Also, all discs contain a trademark of the manufacturer and the stamp of the controlling authority. The radio-control stamp must still be present on the cast discs.

The first digit "5" indicates the width of the wheel rim in inches. The rim width can be: 3.5; 4.0; 4.5; 5.0; 5.5; 6.0; 6.5; 7.0. On seals, sports cars, some SUVs often set wheels with a wider rim. The width of the rim gives an increase in the internal volume of the tyre and can improve its load capacity. When choosing appropriate disks and covers, it is important that the bus profile width is 30% greater than the width of the wheel rim. For example, for sizes of 195/70 R15 (that is, the profile width is 19.5 cm, or 7.68 inches), the disks with a rim width of 5.5 inches will be suitable. The maximum deviation must not exceed +/-1 inch for discs up to 14 inches in diameter and +/-1.5 inches for 15-inch or more diameters. If you use too many disks, the bus profile might be broken. The owls will either stretch or be burned, which will not affect the performance of the car. The machine will be enlisted on the corners and may be taken away by the straight line.
The letter "J" contains information on the shape of the rim flange shape. "J" is the most common type. Other types of paints for passenger cars are JJ, JK, K, B, D, R, or L. These parameters are actually more interesting to specialists. If you are selecting disks, you do not need to consider them.
The next digit "13" is the diameter of the rim in inches. It can be between 10 and 22 inches. Today, many motorists prefer low-profile tires, and this is why there is a tendency of the so-called increase of mounting diameter. This means that if you used a 14-inch drive before, they were put on a 15-inch drive.
The edge of a disc that is designed for an unkable tire, there are a circular flange of the hampa (from an angel). hump is a bulge). Thanks to the hammps, the tyre shall be securely fixed at the turn, excluding the possibility of depressurization of the wheel. The indicator H indicates that there is a projection only along the external side of the disc, and H2 indicates the presence of such protruations on both sides. Drives with two hamps provide a more secure fix for the tyres. Sometimes, to ease the installation, the manufacturers make the hamp truncated. The discs are marked FH or, if two are truncated, FH2 (from English). Flat-flat), X is also used. There are disk drives and asymmetric hammps (AH-Assymetric Hump). On disks with the CH marking (Combination Hump), the champs on the outside are truncated and the internal is normal. The extended hamps are denoted by the character EH2 and the HEN2 + (Extended Hump). The drive with the extended hamps is most efficient when you are installing RunFlat tyres. Sometimes it is possible to do without the hammps: the special shelf SL (the Sesial Ledge) securely keeps the tire on the wheel rim.
"E=29" denotes the departure (or, in other, out) of the disc in millimetres. This parameter is also marked as OFFSET or DEPORT ("exile"). The distance from the disc is the distance between the private plane (the plane to which the disc is pressed against the hub of the wheel) and the centre width of the rim. The benefits can be both positive and negative. If the middle disc is very convex, the departure will be negative, and vice versa-everything depends on how the private plane is located. Too small a flight would increase the load on the wheel; there might be a friction lid on the wing in the case of suspension of the suspension. It will not be possible to install the disc at all: the mid-point will simply be put into the braking machine or other parts of the vehicle suspension. There are other reasons why you can't use the disks that do not have an unestablished departure for this car. When the departure is reduced, the vehicle wheels shall start outside the body, the track shall be wider and the steps and suspension shall be subject to additional pressure. The larger gauge, on the one hand, improves the stability of the car, gives better contact with the road, while turning the steering wheel is heavier, the dynamics of the acceleration are reduced, and fuel is used more. If the catch is increased, the gauge is narrowed and the disc is at risk of being stuck in the brake knot. Only professionals with a lot of experience in working with a car can change their flight. Other parameters are mandatory for wheels when changing wheel departures.
"PCD= 4 x 98" is the number of fixing holes and the diameter of the circle on which they lie (Pitch Pitch Circle Diameter). In this case, the disk has 4 holes, the diameter of the circle is 98 mm. This parameter is particularly important when you are using light-alloy discs that are chosen based on the diameter of the center hole and the peculiarities of the crepeg. Even the minimum differences in the values of these holes on the disc and the hub affect the easing and safety of the movement. If only one bolt is fixed in the center hole, the rest will be fixed with skewed, then when the wheel is rotated, there is no knock-off. It will also increase the load on the bolts or nuts that can contribute to their deployment during the trip.
The "DIA=58.6" parameter defines the diameter of the center hole. This is one of the most important vehicle model disk ratios. If the diameter of the disc is the same as the diameter of the mounting cylinder of the hub, the wheel is absolutely centering. This is possible if you are installing the original automaker drives. If there is a difference in diameter, the disc will have to be aligned with the compaction rings, as well as mounting bolts and coconic and spherical bolts. These manipulations are suitable for cast or forged disks. The diameter of the discs used for the application of the centering rings is excluded, so the diameter of the disc should be the same as the diameter specified by the car manufacturer; only 1 mm is allowed.
The optional settings include the Max Load. It shows the maximum disk load in kilograms or pounds. Disk units for passenger cars have some safety margin. However, installed on a SUV or a minibus, they may be deformed even if there is a slight road roughness.
