What Is The Difference Between Inflatable Tyres And Solid Polyurethane Tyres?

Inflatable tyres offer much better on-road performance (the bike is springy, and therefore, much more comfortable). “Basic” models with solid polyurethane wheels are sold almost exclusively to kindergartens and playgrounds, where it’s not practical to have bikes that require re-inflating and where low maintenance is more important than a comfortable ride.
