What are the best 500/525 – 21 tyres for a vintage 3 Litre Bentley?
The 3L Bentley originally fitted 820X120 Beaded edge tyres in the early 1920s. However by t he middle of the 1920 vintage cars were changing to well based wheels, so the later Bentley 3 Litre fitted 31”X4¼“ tyres. We would suggest the best tyre in that size now, assuming you have 21” well based wheels is the 5.25X21 Firestone.
