If the tire is not checked, it has the potential to cause vibration in the suspension of the vehicle on which it is mounted. In tire retail shops, tire/wheel assemblies are checked on a spin-balancer, which determines the amount and angle of unbalance. Balance weights are then fitted to the outer and inner flanges of the wheel. [2]
Tires have a large influence over bike handling, especially on motorcycles, [9] [45] but also on bicycles. [7] [69] Tires influence bike dynamics in two distinct ways: finite crown radius and force generation. Increase the crown radius of the front tire has been shown to decrease the size or eliminate self stability.
This allows one-shot dynamic balance to be achieved with a single spin, by adding a mass of internally calculated size in a calculated position. This is the method commonly used to dynamically balance automobile wheels with tire installed by means of clip-on lead (or currently zinc) 'wheel weights'.
Tire maintenance for motor vehicles is based on several factors. The chief reason for tire replacement is friction from moving contact with road surfaces, causing the tread on the outer perimeter of tires to eventually wear away. When the tread depth becomes too shallow, like for example below 3.2 mm (4/32 in), the tire is worn out and should ...

Tire uniformity refers to the dynamic mechanical properties of pneumatic tires as strictly defined by a set of measurement standards and test conditions accepted by global tire and car makers. These standards include the parameters of radial force variation , lateral force variation , conicity, ply steer, radial run-out , lateral run-out , and ...
The front wheel will then rotate about the steering axis to the left and the tire will generate forces in the contact patch to the left. The machine as a whole steers to the left. Because the forces in the contact patch are at ground level, this pulls the wheels "out from under" the bike to the left and causes it to lean to the right.
