Panhard - Panhard (Veteran and Vintage)
Panhard-Levassor built a prolific number of car types, stating in the early 1890's, when the wheels had a steel band on them. But as an optional extra one could have a solid rubber exterior which made for a quieter ride. I believe this idea was first used in Paris on horse drawn carts so that residents would not be woken in teh early hours by deliveries. When pneumatic tyres were being fitted to the cars in the Veteran and Vintage period, remember many of these sizes became obsolete within a short period. Subsequently so many cars would have had a change of tyre size early on in their history, replaced with sizes more readily available, which we probably produce (or are producing) today.
