Description

Technical Field

[0001] The utility model relates to an adjustable wheel rim, belonging to the field of wheel rims. Background Art

[0002] When the tire is installed on the rim, the inner diameter of the tire must match the calibrated diameter of the rim to ensure the fit of the tire. The difference in the setting of the inner diameter of the tire has a greater impact on the fit during the installation process, among which the circumference of the wire ring of the tire bead has a greater impact on the inner diameter.

[0003] Generally, the circumference of the tire bead wire ring should be consistent with the circumference of the wire ring during actual production to ensure good fit after the tire is installed on the rim. However, in order to avoid adding too many accessories and achieve interchangeability in the production process, and to avoid difficulties in tire installation due to too tight fit caused by too small circumference of the tire bead wire ring, the circumference of the tire bead wire ring is usually appropriately corrected. In fact, the size correction range is not easy to grasp. When the circumference of the wire ring is too large, the fit between the tire and the rim is too loose during tire installation, which is prone to slippage or abnormal noise due to relative displacement between the tire and the rim.
