What are trailer wheels
The wheel rim is a component that installs the tire around the wheel, also known as the wheel, and is a rotating component that connects the wheel and the axle, responsible for carrying load between the tire and the axle. The function of the wheel rim is to bear the burden on the wheel together with the tire and dissipate the heat generated by the tire.
Rims are components that fix tires to the wheels, and in our daily lives, many people refer to them as wheels. The wheel hub is a rotating component that connects the wheel and the axle, responsible for bearing the load between the tire and the axle. The spoke is the component that supports the rim and wheel hub.
The wheel rim is the inner framework of the tire, which is directly connected to the aforementioned wheel hub through wheel bolts. Usually referred to as "steel rim" or "wheel rim." It has two types of materials: casting and welding. Commercial and low-end passenger vehicles typically use welding materials for cost reasons. High-end passenger cars are usually made of cast aluminum alloy.
The wheel hub is a rotating component connected to bearings, shaft heads, brake discs, rims, and other features.

How to measure trailer wheels
You may not think your trailer wheels are exceptionally professional, but many specific measurements must be just right. The size of the wheels ensures smooth flow with other spins and ensures that the goods you carry on the trailer can reach your destination smoothly and safely. When measuring trailer wheels, paying attention to several specific dimensions is necessary.
The wheel's centerline is the precise center of the wheel, measured from front to back. Trailer tires must be balanced around the centerline to function correctly.
The wheel diameter is the distance measured on the most extended trailer wheel at the location of the tire and wheel seal.
The bolt diameter is the distance between the holes securing the wheel to the trailer.
The mounting pad is the part where the center of the wheel comes into contact with the surface of the trailer hub.
The drum side is the side where the wheels face the trailer and drum.
The street side is the side where the trailer wheels face the street.
Backspace refers to the distance between the installation pad and the edge of the trailer wheel drum.
Wheel offset is the space between the centerline of the trailer wheel and the mounting pad.
How to manually install the tire on the rim?
If there is no valve stem, insert the valve stem.
Use a small amount of tire lubricant to lubricate the valve stem, and then press it into the hole in the rim, which the tire will later cover. Next, take a pair of pliers and pull the valve stem out of the hole
Lubricate the tire beads and rims.
Although tire lubricant is essential for machine-mounted tires, it is crucial for manual installation. Apply a large amount of oil to the inner and outer edges of the wheel rim.
Place the rim flat on the ground and place the tire on top
If the environment you work on is asphalt or concrete, place a piece of cardboard under the wheels to avoid scratches. Ensure that the working surface is flat, uniform, and stable. The tire will be located at the top of the rim, and its bottom bead will contact the upper lip of the rim. Unlike machines, try to ensure that the tires are flat on the rims.
Place the rim flat on the ground and place the tire on top
When you step on one side of the tire, ask a friend to help maintain balance. Then lift the other foot and apply pressure to the other side, forcing the bottom bead of the tire to pass down over the upper lip of the rim. You may need to jump slightly to apply enough downward force to push the tire bead over the lip.
Add more lubricant to the upper bead and rim of the tire.
After the lower bead is seated, the real challenge will be to keep the upper bead tightly behind. Apply more lubricant to help press the rubber onto the metal, making it more accessible. The bottom tire bead does not require more lubricant.
Press the upper lip of the tire down onto the rim on one side.
Tilt the tire so that a portion of the upper tire bead is lowered below the rim edge. If the tire itself cannot entirely pass through the lip, press down on the lower part of the tire. You need to leave enough space between the upper bead of the tire and the upper lip of the rim to slide the pry bar into the gap. You may even need to use a pry bar to create gaps. If that's the case, once you're done, put it in the appropriate position.
Use a pry bar to press the tire lip onto the rest of the rim.
Move around the wheel, press the tire down with your hand, and pry its bead onto the upper lip of the rim. This will require a considerable amount of work, but it should be completed when you take a turn around the steering wheel
Inflate the tire with an air compressor
Once both beads of the tire exceed the edge of the rim, you can install an air compressor on the valve stem to inflate the tire. When the tire is inflated, be sure to keep your fingers and clothes away from the tire bead.
