Numarical values like 4 , 4.5 and 6 shows rim width in inches and alphabetical letters like B Or J shows type of rim contour. Now-a-days only J type contour rim are being used in whole the world.To get 4.5j rim u will have to mention tyre size only,for example 155/70R - 12 tyre size usually requires 4.5 inch rim width.
