   A Tri-Star wheel assembly rotating through a hole. The tri-star is a novel wheel design—originally by Robert and John Forsyth, assigned to Lockheed in 1967—in which three wheels are arranged in an upright triangle with two on the ground and one above them.

   For example, a 32 spoke wheel has 16 spokes per side, 360° divided by 16 equals 22.5°. Multiply 22.5° ("angle between adjacent flange holes") by the number of crossings to get the angle a—if 3-crosses, the 32 spoke wheel has an angle a of 67.5°.

   For a normal wheel size and spoke count, only the latter is suitable for a wheel that has to transmit torque from the hub to the rim, as with rear wheels or hub brakes. This rule is occasionally broken where a very large number of spokes is used, or the wheel is unusually small in diameter, either of which reduces the amount of increased ...

   The LeMans was another 4-spoke, 4-lug design, cast in sizes and fitments for sports cars such as Alfa Romeo, MGB and Datsun 240Z. Each tapered spoke was wider at the hub than at the rim, giving a lightweight appearance similar to Ferrari wheels of the period. BRE 240Zs used these wheels in the SCCA competition, and street-driven 240Zs followed ...
