What to know about tires and 6×2 configurations

There are many benefits to utilizing a 6×2 axle configuration, and there are as many options and issues to consider. Fleets can save a lot of money on tire wear and replacement, but choosing 6×2 isn’t a decision to take lightly. From “pushers” and “tags” to determining the amount of torque a vehicle needs, there is a lot of information to consider.

Key Takeaways:

• Many commercial fleets are evaluating the benefits of specifying new tractors with a 6×2 configuration versus the more popular 6×4 configuration.
• Fleets are showing a 2 to 4% improvement in fuel economy using 6×2 configurations, which is a significant improvement.
• Treadwear is accelerated on the drive axle with 6x2s since all of the engine driving and engine braking torque passes through the single axle drive tires.

“Fleets have reported a drop in drive tire removal mileage on 6x2s— as high as 50%. On the non-driven, free-rolling axle, spec’ing a trailer rib tire versus a typical drive tire lug design is appropriate.”
