Tires and brakes-a forced relationship

摘要

The biggest engine, the most powerful brakes, and the most sophisticated suspension systems are only as good as the power they transfer to the pavement. Tires are the sole connection through which all of these essential forces are directed. Thaf s taken for granted until there's a brake skid, the vehicle fails to negotiate a curve, or becomes stuck. This is the main reason why over-the-road truck tires are now axle specific. For the most part, tire casings are essentially the same for steer, drive and trail designs. The tread patterns, tread'depth (therefore tire weight), and sometimes even tread rubber compounds differ by axle to optimize wear and performance. Differing force transfer requirements are the reason why drive tires wear much faster onrnforce.
