As Formula One wheel rim diameter size will switch from 13 to 18 in (330 to 457 mm), the tyre diameter of 2022-spec Pirelli Formula One tyres will also be altered, from 670 to 720 mm (26.4 to 28.3 in), while the tread width of 2022-spec Pirelli Formula One tyres are expected to be unchanged.
A four-wheel version of the Scarab was produced, named "Scarab Four". It was based on the Standard Atlas van chassis, later called the Leyland 20. This chassis was not well-adapted to the job and it was not a great success.

Diagram of turning vehicle. On wheeled vehicles with the common type of front wheel steering (i.e. one, two or even four wheels at the front capable of steering), the vehicle's turning diameter measures the minimum space needed to turn the vehicle around while the steering is set to its maximum displacement from the central 'straight ahead' position - i.e. either extreme left or right.
The intention of Ackermann geometry is to avoid the need for tyres to slip sideways when following the path around a curve. [3] The geometrical solution to this is for all wheels to have their axles arranged as radii of circles with a common centre point. As the rear wheels are fixed, this centre point must be on a line extended from the rear axle.
The Leibniz wheel was used in many calculating machines for 200 years, and into the 1970s with the Curta hand calculator, until the advent of the electronic calculator in the mid-1970s. Leibniz was also the first to promote the idea of an Pinwheel calculator .
