This increased radius improves the ability to maximize your weight allowance on the steering axle. The extra frame rail length also allows room to mount generators or tool boxes. For the most part, I’ve also found a longer wheelbase generally improves resale value as the truck is more versatile in most cases.
What is the point of stretching a semi?
Re: Why stretch a Semi? In the days before interstates most of the highways in the west were blacktop. The idea then was as the front axel passed over a point it would set up a vibration in the blacktop. With a longer WB most of the vibration would stop before the rear axle passed over the same point.
Why do semi truck drivers leave their trucks running?
Truckers, both independent owner-operators and fleet drivers, leave their engines idling for three main reasons: weather conditions, economic pressures, and old habits. In cold weather, a truck’s engine and fuel tank need to stay warm.
Why do semi trucks tilt?
Too much centrifugal force—caused by an improperly balanced load, excessive speed, or a curve that’s too tight for a truck to safely travel at normal speeds — can cause the truck to tip over.
What is the point of stretching?
Why stretching is important Stretching keeps the muscles flexible, strong, and healthy, and we need that flexibility to maintain a range of motion in the joints. Without it, the muscles shorten and become tight.

Is it bad to let a diesel idle for hours?
It is true that diesel engines use barely any fuel while idling, far less than a gasoline engine. While it isn’t particularly bad for it, there just isn’t much reason to do it; most diesels start perfectly fine when cold, warm up in a reasonable time, and don’t have gelling issues.
Why are semi truck drivers so rude?
Truck drivers are often perceived to be rude for one simple reason: inertia. Trucks have a lot of inertia and therefore take a lot longer than cars to safely slow down, speed up, or change lanes. Such slow responsivity can seem like rudeness to other drivers.
Why do trucks lift their wheels?
Echoing what others have said, lifting axles save tyre wear and reduce rolling resistance on empty or partly loaded vehicles. Lifting axles are non-driven, so lifting an axle can transfer weight to a driven axle to aid traction but this can put the drive axle over its weight limit in the process.
Do trucks flip over easily?
You might not realize, but large trucks can rollover easily if the conditions are right. Because of their design, tractor trailers rollover more often than regular vehicles. They have a higher center of gravity, which can be thrown off more easily than a passenger vehicle.
What is the average mpg for a semi truck?
In 1973, federal agencies estimated that semi trucks got 5.6 miles per gallon on average. Today, that number is around 6.5 miles per gallon on average. But remember, that’s on average. It’s been reported that some diesel semi trucks achieve 8 mpg or more.

Why do Michigan trucks have so many axles?
Vehicle braking capability and resistance to overturning are improved by having more axles and wheels, each of which is equipped with brakes, and by carrying lower weight per axle. Congestion on Michigan’s highways is reduced because fewer trucks are required to move our freight.
What is the legal weight per axle on a semi?
In addition to Bridge Formula weight limits, Federal law states that single axles are limited to 20,000 pounds, and axles spaced more than 40 inches and not more than 96 inches apart (tandem axles) are limited to 34,000 pounds. Gross vehicle weight is limited to 80,000 pounds (23 U.S.C. 127).

Federal limits are 80,000 pounds gross vehicle weight, 20,000 pounds on a single axle, and 34,000 pounds on a tandem axle group. There are also Federal standards for length and width on the National Network (NN).
How do you measure wheelbase on a semi truck?
Manufacturers advertise wheelbase according to the distance from the center hub of the steer axle, to the center-point between the two rear wheels on a three-axle truck. So, stick a ruler vertically in the ground right in between the two rear tires, and measure from there to the steer axle.
