The pneumatic railroad tire developed by Michelin offered a number of advantages over the traditional wheel type in this relatively lightweight application. Passengers experienced a smoother, quieter ride. Better traction resulted in faster acceleration, shorter braking distances and improved climbing ability on grades.

Downside factors included higher fuel consumption caused by increased drag and the possibility of flats. http://theoldmotor.com/?p=107711
