How do you calculate turning radius?
The distance from the first mark to the furthest mark is your turning circle, or the space your vehicle needs to do a U-turn without hitting a curb. Divide this measurement by two to get your “turning radius.” This information is almost useless in the real world, but it’s nice to say you have it.
What does WB mean on a truck?

With the 53-footer’s tandems set all the way forward, the wheelbase measures 400 inches. With a 10-degree angle of truck to trailer the turning radius is 2,312 inches, or 192 feet. Increase the turning angle to 45 degrees, and turn radius decreases to 565 inches or 47 feet.
What is the average turning radius of a semi truck?
The outer turning radius necessary for a medium-sized semi truck making a a 180° turn should be between at least 40′-40’10” | 12.2-12.4 m.
Is a higher turning radius better?
The lower the number (number = feet), the tighter the truck will turn. Which is better depends on the type of work you are doing. Longer wheelbase trucks (larger turning radius) usually ride much smoother than short wheelbase (tighter turning radius) trucks.
