The steel wheel rim is the part that mounts and supports the tire on the perimeter of the wheel, and forms the wheel with the spokes. The rim and spokes can be integral, permanently attached or detachable.
What are the precautions for using steel wheel rim?
How to see the parameters of Aluminum alloy wheel rim?
What are the structure and material of steel wheel rim?
Since the steel wheel rim is the base for assembling and fixing the tire, when the tire is mounted on different rims, its deformation position and size also change. Therefore, it is best to use the specified standard rims for each type of tire, and if necessary, rims with similar specifications to the standard tires (allowable rims) can also be used. If the steel wheel rim is not selected properly, it will cause early damage to the tire, especially when used on a rim that is too narrow.
Specifications of Aluminum alloy wheel rim: International standard tire code, expressed in millimeters as a percentage of section height and aspect ratio, followed by: tire type code, rim diameter (inch), load index (allowable bearing quality code), Allowable speed code. For example: 175/70R 14 77H in 175 means the tire width is 175MM, 70 means the aspect ratio of the tire section is 70%, that is, the section height is 70% of the width, the rim diameter is 14 inches, the load index is 77, and the allowable speed is H class.
Generally speaking, steel wheel rims are made of steel and aluminum alloys. At present, almost all civilian models are made of aluminum alloy rims. In the past, low-end cars would use steel rims, but now some trucks are generally using them. Aluminum alloy rims are generally divided into casting and forging in terms of technology. Forging is more advanced than casting and has better performance, so most of the original rims of family cars are cast aluminum alloys. Forged ones are generally found on high-end cars, or specially modified brand rims.
The rims of the above materials are similar in structure and can be one piece, one piece. Then the number of spokes is different, ranging from 3 spokes to multi-spoke. Forged rims are also derived from special structures, one-piece, two-piece and three-piece. One-piece is an ordinary, two-piece forged rim like casting. The outer ring and the middle spokes are separated and connected by rivets. The style of the rim can be changed by changing the style of the spokes. Three-piece On the basis of the two-piece, the rim is divided into a rear piece and a front piece, which is more complicated.
Two-piece and three-piece forged rims are generally less configured in the original factory, and are generally made by modified brands, and the effect is very cool.
