Super single tires (in place of the more common dual tire set-up) on semi-trailers could actually save weight, cost, and — when combined with side guards — lives! Sounds like a Win/Win scenario to me! But don’t take my word for it, read about the potential benefits in this truck driver blogpost:
Essentially, instead of having eighteen tires to support the trailer and truck, only ten will be needed because of the improved design of the tire itself. The super single truck tires can withstand the weight of the trailer and vehicle over the same time period as their dual counterparts. A study performed by the Oak Ridge National Laboratory showed that trucks could save an average of almost 3% on gas or diesel fuel. While 3% may not sound like much, over 125,000 miles and averaging five miles per gallon that results in a savings of 728 gallons per year.
In addition, the new tires actually offer more stability with a wider truck frame. However, the most interesting advantages are that these tires can hold up for about 200,000 miles as opposed to the standard 160,000 miles for the conventional tires. This means that money is saved on replacement as well since the fewer number of super singles which actually last 40,000 miles longer.
However, the main advantage that super singles offer is that they are stronger, yet lighter in weight than their standard counterparts by roughly 1,000 pounds in total. While this weight savings may translate to better fuel mileage, trucking companies see this as being able to add 1,000 more pounds to the cargo. This means that more can be hauled on a single trip which can earn the company even more money than before.

Possible Drawback (as mentioned in the video below) is what could happen when there is a tire blow-out.
