WHEEL GEOMETRY: PARALLELISM, CAMBER, CASTER… WE EXPLAIN EVERYTHING

 To drive straight, good wheel alignment is necessary. It consists of several parameters, including the famous parallelism. This is an important point for safety as well as for not accelerating tire wear. Here is what you need to know to measure all the interest. Let's put things straight. Geometrically speaking, a wheel is always round and perpendicular to the ground. But the geometry of a wheel, in mechanics, is much more subtle than that. Impossible to observe it with the naked eye, except for the most pronounced settings, but the inclination of the wheels, however slight it may be, has a direct impact on the behavior of the vehicle as well as on its wear (the wear mainly tires).
