When non-standard rubber is installed on UAZ, the problem arises of the correct selection of a disc for tires with different sizes and characteristics. In addition to the type of wheel itself (stamped, cast, forged), it is necessary to take into account other important parameters that affect the compatibility with the car and the size of the tires.
Instructions
Step 1
First of all, pay attention to the width of the rim of the disc. As a rule, it should be 25-30% less than the tire profile width. Installing rims that are too wide or too narrow will violate the design tire profile. In other words, the sidewalls of the tire will either be compressed by the edges of the rim, or stretched on it. In this case, the driving characteristics of the rubber will be significantly deteriorated: response to a turn, drag resistance and lateral rigidity
Step 2
Next, look at the diameter of the disc. This is the main parameter that determines the compatibility of tires with wheels. Obviously, when switching to rubber of a larger outer diameter, disks with an increased landing size will also be required. A larger steel wheel will undoubtedly be heavier than the standard one. To compensate for this increase in mass, select a disc made of light alloy.
Step 3
Look at the location of the mounting holes and the number of these holes. They are designated by the PCD index. For example, PCD200 / 6 designates six holes on a diameter of 200 mm. Pay special attention to this parameter: it is easy to make a mistake by a few millimeters, and it is extremely difficult to install tires on incorrectly selected rims.
Step 4
For UAZ vehicles, the wheel offset parameter is of no small importance. It denotes the distance between the longitudinal plane of symmetry of the rim and the mounting plane. The overhang can be zero, positive (the disc hub is protruding outward) and negative (the hub is recessed). Standardly designated by letters ET and numbers equal to the departure value.
Step 5
For some widening of the UAZ track, select discs with a lower offset than the standard ones. But do not overdo it: reducing the overhang overloads the hub bearings and suspension. Avoid extended overhang discs. It may be difficult to install: the brake disc will simply rest against the brake mechanism.
Step 6
Even with a simple change from a steel disc to a cast one, take care of purchasing bolts (or studs) longer than standard ones. This is due to the fact that the light-alloy wheel is always thicker than the stamped steel. In addition, the new disc may have a different bolt fastening method and you will need to purchase the appropriate bolts.
