A new tire profile, based on the studies of Prof. Heumann, was designed and is illustrated. This tire profile should assist in ensuring good riding qualities, increase the resistance against derailment and this in turn should reduce tire and rail wear, and ensure a favorable wear pattern. This can be done by ensuring one-point contact running and a gradual transition of the throat profile. The result of trials carried out with standard 32 ton British Railways coaches running on B4 type bogies with 3-ft. wheels, positive axle guides, 19-1/2 in. effectively long swing-links and helical springs throughout are shown. Ride index values during acceleration and wear patterns for the tires are given. The tests have shown beneficial results, although further tests are needed.
