Variants of the Formula Vee rules exist in Australia, Brazil, Canada, Germany, the UK & Ireland, South Africa, and New Zealand. Particularly notable is Formula First, racing in the US and New Zealand, which employs the same chassis, but with later model Beetle parts, a larger 1,600 cc (98 cu in) motor (New Zealand uses the 1,200 cc [73 cu in] variant) and other upgraded components such as disc ...
Tire balance measurement is a test where the tire is automatically placed on wheel halves, rotated at a high speed and measured for imbalance. Large commercial truck/bus tires, as well as some passenger and light truck tires, are inspected by X-ray or magnetic induction based inspection machines, that can penetrate the rubber to analyze the ...
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 tire wars during this period has been cited as a reason for six-car start at the 2005 United States Grand Prix. [29] After Michelin left at the end of 2006, Bridgestone became the sole tire supplier of Formula One until 2010, [30] when Pirelli took over the duty as Formula One's sole tire supplier, a status it maintains as of 2024.

Toyo Tires F1600 Championship Series is an open-wheel racing championship series based in Ontario, Canada. It features cars powered by 1.6L engines produced by both Ford and Honda. It is sanctioned by the CASC, Ontario region. It has two distinct classes: the A Class for the newer chassis and the B Class, for cars manufactured in or before 1994 ...
Tire load sensitivity describes the behaviour of tires under load. Conventional pneumatic tires do not behave as classical friction theory would suggest. The load sensitivity of most real tires in their typical operating range is such that the coefficient of friction decreases as the vertical load, Fz, increases.
Softer tires also cushion against rough terrain and road damage, such as washboarding, more effectively. Reducing tire pressure also reduces the extent to which the tires grind against loose surfaces, significantly reducing dust and silt. Another function of CTIS is to maintain tire pressure if there is a slow leak or puncture.
For a real-world tire, the circle is likely to be closer to an ellipse, with the y axis slightly longer than the x axis.) In the example, the tire is generating a component of force in the x direction ( F x ) which, when transferred to the vehicle's chassis via the suspension system in combination with similar forces from the other tires, will ...
