What is Trailer Rim？

Rims are components that install tires around the wheels, also known as wheels, and are rotating components that connect the wheels and axles, responsible for carrying loads between the tires and axles. The function of the wheel rim is to bear the load on the wheel together with the tire and dissipate the heat generated by the tire.Rims are the components that fix the tires in the wheels, and in our daily lives, many people refer to them as wheel hubs. The wheel hub is a rotating component that connects the wheel and axle, responsible for bearing the load between the tire and the axle. The spoke is the part that supports the rim and wheel hub.The wheel rim is the inner frame for installing tires, which is directly connected to the wheel hub mentioned above through wheel bolts. Commonly known as "steel rim" or "wheel rim". It has two types of materials: casting and welding. Commercial vehicles and low-end passenger cars generally use welding materials due to cost reasons. High end passenger cars are generally made of cast aluminum alloy.The wheel hub is a rotating component that is connected to bearings, shaft heads, brake discs, rims, and other components.

How to Measure a Trailer Wheel？

You may not think of your trailer wheels as being particularly specialized, but there are actually many specific measurements that must be just right. The wheel's size ensures that it flows smoothly with the others and that the cargo you are carrying on the trailer has a smooth, safe ride to your destination. When you're measuring your trailer wheel, you need to pay attention to several specific dimensions.

• The wheel centerline is the exact center of the wheel, measured from front to back. The trailer tire needs to be balanced around the centerline for proper operation.
• The wheel diameter is the distance across the trailer wheel at its longest, measured at the spots where the tire seals with the wheel.
• The bolt diameter is the distance across the bolt hole where you will secure the wheel to the trailer.
• The mounting pad is the part of the wheel in the center that touches the face of the hub on your trailer.
• The drum side is the side of the wheel that faces your trailer and drum.
• The street side is the side of the trailer wheel that faces the street.
• The backspace is the distance between the mounting pad and the edge of the trailer wheel on the drum side.
• The wheel offset is the space between the centerline of your trailer wheel and the mounting pad.

How to Put Tires on Rims by Hand?

1. Insert the valve stem if there isn't one present.Use a little tire lubricant to lubricate the valve stem, then press it into the hole inside the rim, which the tire will later cover. Next, take a pair of pliers and pull the valve stem out of the hole
2. Lubricate the tire bead and rim.Although tire lubricants are important for installing tires with machines, they are crucial for manual installation. Apply a large amount of lubricant to the inner bead and outer edge of the tire rim
3. Lay the rim flat on the ground and place the tire on top of itIf the ground you work on is asphalt or concrete, place a piece of cardboard under the wheels to avoid scratches. Ensure that the surface of your work is flat, uniform, and stable. The tire will be located at the top of the rim, with its bottom bead touching the upper lip of the rim. Unlike machines, try to ensure that the tires are flat on the rims.
4. Lay the rim flat on the ground and place the tire on top of itWhen you step on one side of the tire, ask a friend to help maintain balance. Then lift your 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 a little to apply enough downward force to push the tire bead over the lip.
5. Add more lubricant to the upper bead on the tire as well as the rim.After the lower bead is seated, the real challenge will be to keep the upper bead closely behind. Apply more lubricant to help press rubber onto metal, making it easier. The bottom tire bead does not require more lubricant.
6. Press the upper lip of the tire down onto the rim on one sideTilt the tire so that a portion of the upper tire bead is lowered below the rim edge. If the tire cannot fully pass through the lip on its own, 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 place.
7. Use a pry bar to force the tire's lip over the rest of the rim.Move around the wheel, pressing down onto the tire with your hands and prying its bead over the upper lip of the rim. This will take a fair amount of work, but should be done by the time you make it all the way around the wheel once
8. Inflate the tire with an air compressorOnce both beads of the tire are past the rim's lip, you can attach an air compressor to the valve stem and inflate the tire. Be sure to keep your fingers and clothing clear of the tire bead as the tire inflates.
