Don't feel bad, this confused me for the longest time. You should first pick a tire you want to use, then choose an appropriate rim.
Tire sizes go as follows (example) 20x10x9
20 = Tire height
10 = Tire Width
9 = Inner diameter OR rim diameter needed
BUT, when looking at rims (example) 10x9
10 = Rim Diameter
9 = Rim Width
In my opinion you can run a tire 2 inches (3 max) wider than a rim. The inner tire dia. and the rim dia. MUST match.
If you're looking at tires 22x12x9
You need to make sure the 1st number in the rim size is "9" (in this case) and the 2nd number in the rim size is within +0/-3 inches of tire width (9 to 12).
So for the above tire size you could get away with an 9x9, 10x9, or 11x9 if they make one that large.
Finally, you might see the following numbers when referencing rims .160 & .190 This is the rim thickness in inches.
.190 is a heavy duty rim which can handle a lot of abuse.
.160 is stronger than stock
Hope this helps.
