The ratio of between-tyre span to kiln diameter settled down to a mean value of about 6. The total mass of wet process kilns increased in proportion with their output, and kilns were designed with as many as eight tyres. The emergence of dry process kilns brought about a return to the use of short kilns with three tyres.
