Why do trucks tilt?
The trend is inspired by Baja racing, which was popular in the desert terrains of California. The idea is, when a Baja truck hits a jump at a higher speed, to land its rear first, thus avoiding nose-dive, which could potentially total the truck and would mean the end of the race for that competitor.
Why do semi trucks pull to the right?
Whether the truck is drifting gradually or darting rapidly to the right or left, the cause is usually improper tire inflation. Constant pulling in one direction or the other could also be “radial pull,” if you’re running radial tires. An easy way to tell is to switch tires side-to-side and see if the problem goes away.

Why does my truck pull to the right after alignment?
One of the most common reasons your car will pull to one side is because the wheel alignment is off.

However, a more serious symptom of misaligned wheels is uneven tread wear.
Why do semi trucks twist?
The rear wheels effectively allow the truck to ‘pop a wheelie’, i.e. lifting the centre of mass by a certain amount. The frame of these trucks is flexible enough to allow some torsion, and it wouldn’t take much to bias the rotation to one direction.

It’s because the shape of the car uses Bernoulli’s principle: the difference of pressure between the air above and below the car causes a net upwards vertical force which increases when the car goes faster.
