A rubber-tyred metro or rubber-tired metro is a form of rapid transit system that uses a mix of road and rail technology. The vehicles have wheels with rubber tires that run on a roll way inside guide bars for traction. Traditional, flanged steel wheels running on rail tracks provide guidance through switches and act as backup if tyres fail ...
Single axle running gear on a self-discharging hopper. In railway terminology the term running gear refers to those components of a railway vehicle that run passively on the rails, unlike those of the driving gear. Traditionally these are the wheels, axles, axle boxes, springs and vehicle frame of a railway locomotive or wagon. [1]
Some rubber-tyred metros feature special wheelsets with rubber tyres outside of deep-flanged steel wheels, which guide the bogie through standard railroad switches and keep the train from derailing if a tyre deflates. The system was originally conceived by Michelin for the Paris Métro; the first line opened in 1956.
Running wheels (also known as road wheels or tractor wheels): positioned on the top of the rail, bearing the weight of the train. Side friction wheels: positioned on a horizontal plane, either inside or outside of the rails. These hug the sides of the rail, keeping the train centered. Up-stop wheels (also known as underfriction wheels or up ...

A train wheel or rail wheel is a type of wheel specially designed for use on railway tracks. The wheel acts as a rolling component, typically press fitted onto an axle and mounted directly on a railway carriage or locomotive , or indirectly on a bogie (in the UK), also called a truck (in North America).

The most usual cause of damage is drag braking on severe gradients.Because the brake blocks apply directly on the tire, it is heated up, relaxing the interference fit. It is not feasible to fit the tire with such a heavy interference as to eliminate this risk entirely, and the retaining ring will ensure that the tire can only rotate on the wheel center, maintaining its alignment.
