Rolls Royce 25 - 30 Tyres


  • The Rolls Royce 25/30 drives really nicely with the 5.25/6.00 x 19 Michelin D.R.
  • A 25/30 Royce also works well with the 6.50 x 19 Custom Classic which is excellent value.
  • 25-30 wheels require innertubes, and the reinforced Michelin 19/20H RET innertubes are the best fit for these tyres.
  • For a 25/30 our suggested tyre pressures would be between 34psi and 40psi depending on the body.

History of the Rolls Royce 25/30

The Rolls-Royce 25/30, produced between 1936 and 1938, is an improved version of the 20/25 with a bigger engine to offer more power, as over-large bodies were frequently attached to previous models, resulting in complaints about its performance. The in-line six-cylinder overhead valve engine is identical to that used in the 20/25 but has a larger capacity of 4257 cc. The Rolls-Royce carburettor was replaced by a single Stromberg downdraught carburettor, and magneto ignition was no longer used, however, a backup coil was provided. Third and top gears were outfitted with synchromesh.

The inflexible front and rear axles were still supported by half elliptic springs with hydraulic dampers. A mechanical servo assists with braking on all four wheels. For the handbrake, separate rear brakes are installed. Rolls-Royce only produced the chassis and mechanical elements. The body was constructed and installed by a coachbuilder chosen by the owner.
