Wide-base tires aren’t cheap. Not that duals are cheaper, but in a single wide-base tire you have an investment approaching the cost of a pair of standard tires. Minimizing the life-cycle cost of those big wide tires almost demands that they be retreaded.
Most of the low-hanging aerodynamic fruit has already been plucked from the engineering tree. Truck makers and their design teams are now actively exploring options they would have ignored a decade ago. It's all about the cost of fuel.
The big shift to slope-nosed aero trucks began nearly 20 years ago, and since then engineers and designers have been refining the design. Today we see tweaks and twists yielding just the tiniest of gains, yet they are all steps in the right direction. What follows is a pictorial review of some of the changes we've seen in recent years -- some dramatic, some very subtle, but all aimed at killing fewer bugs.

While natural gas has pushed its way to center stage in the alternative fuels discussion, the investment in equipment and infrastructure make it less than appealing to many fleets. However, anyone who is currently running on diesel fuel can easily switch to a greener alternative without that type of up-front investment. They simply have to fill up their fuel tank with biodiesel.
Bridgestone Commercial Solutions introduced a new edition to its Ecopia product line. The R268 premium all-position radial for regional and pickup and delivery fleets providing tire performance that stands up to high scrub environments while offering fuel efficiency advantages too.
A dual-fuel conversion system can offer some of the fuel- and emissions-saving benefits of a natural gas engine without going out and buying a brand-new truck. Read more in this story from the September issue of HDT.
