While all trailers use wheels, their design and construction can vary greatly, from inexpensive stamped steel to high-tech forged alloy examples. Most people base their wheel selection on looks and price, but the process of picking  the right wheels for your trailer should go much deeper. Aluminum alloy wheels, sometimes referred to as just "alloy" or even "mag" wheels, have some serious advantages over basic steel ones.

For starters, aluminum alloy wheels, by nature, better dissipate heat and provide more rigidity  under high-load cornering maneuvers. Alloy wheels are usually lighter than steel wheels, which reduces "unsprung" weight, (all weight that is not supported by the suspension). Any reduction in wheel weight reduces the amount of inertial weight at the rotational axis. The less weight there is spinning around, the easier it is to turn the wheel and the easier it is for the suspension to control wheel and tire movements, while reducing fuel consumption.
