I am pretty sure how to read the sizes for passenger tires... the 225/60R15.
But what about 8.25x20? I know the 20 is rim diameter (I hope). But what does the first number equate to?

The same as your example of 225, which is the metric cross section. | | | | | Joined: Dec 2003 Posts: 2,733 Shop Shark | | Shop Shark Joined: Dec 2003 Posts: 2,733 | Farber.. using your example it takes a 6.5" wheel width. 9:00 takes a 7" and a 10:00 uses a 7.5" wheel. | | |
