Bentley - Derby Bentley 4 1/4 litre

The Derby 4 1/4 Bentley was introduced in 1936, as a replacement for the earlier 3 1/2 litre model. This coincided with Rolls Royce replacing their 20/25 model with the larger 4257cc engine 25/30 model, which was carried onto the new Bentley. Many other refinements were also included which had evolved over the production of the earlier Bentley 3 1/2 litre. The jump in engine size and performance also helped with the other brands which the customer had a choice. By 1939 the MR and MX chassis had overdrive as standard.

Tyre sizes for the Bentley 4 1/4 are dependent on whether you have the earlier cars 18" wheels or the later cars 17" wheels. Tyre sizes are:

- The earlier Bentley 4 1/4 had the same wheels as the earlier 3 1/2 Derby Bentley, namely 550x18. Blockley produce these tyres in 2 tread patterns, and earlier style 3 stud and a later pattern "A6C" pattern. The later Bentley 4 1/4 (from 1938 onward) originally were fitted with 650x17 which Blockley also produces. there is no 17" tyre available that we would wish to use, which is why we produced this low volume size.
