South Africa automotive trailer wheel rims are round shaped wheel rims on which the tires are mounted. It is the exterior edge of wheel that holds the tire. The materials used to manufacture wheel rims include steel, magnesium, and aluminum alloy, among others. Trailer wheel rims are specifically designed to bear large amount of load for transportation purposes. These rims are located at the middle of a tire to support the wheel in different conditions and also to support the tire alignment when the vehicle is moving.
Vehicles use wheel rims with high positive offsets which puts the tire closer to the frame of the vehicle, while South Africa automotive trailer wheel rims are designed to have a zero offset so that there is even tread wear as they tend to deal with heavier loads. Trailer rims are not made to the same tolerances and specs that car and truck rims are made. They are often made with cheaper materials and will go out of round when used over extended periods in normal driving situations. They are also both stronger and cheaper compared to the alloy wheel.
Since the primary duty of a trailer wheel rim is supporting a vertical load, rather than gripping an automobile through turns, trailer rims do not have to be dynamically balanced like passenger car rims do. While 5-Bolt on 4.5" is standard and by far the most common among trailer wheel 5-bolt patterns, there are times in which the trailer manufacturer uses a different pattern such as 5 on 5". The vast majority of trailer wheels with a 6 bolt lug pattern will have a spacing of 5-1/2" whether that be on a 15" or 16" diameter wheel.
There is a growing demand for trailer rims from the road transport and logistics sector, as the road transport sector in South Africa is considered the backbone of South Africa's economy. Moreover, with the increasing demand for heavy vehicles in the country, the demand for trailer wheel rims is also increasing with a rapid pace in South Africa.
