A high quality "straight sidewall" tire with a tough 8-ply sidewall. Suitable for 23 inch wheel rims (split or pit rim), for cars such as the 20hp Rolls Royce, Sunbeams and many other cars. This tire has the authentic original 3 stud pattern from the Vintage period, and the Blockley 33x4 1/2 tire has the largest diameter of any 32x 41/2 available anywhere. This is a popular tire size ranging from cars such as the 20hp Rolls Royce to the rear wheels of the Ford Model TT truck from 1923, although many of these Fords also used 20" and 21" tires . . .
