Wheel Size

[trx450jason]

I have 18x10-8 size rear tires and I need to know what size rim these would fit on. I want to make sure I order the right size. Thanks.

18 is the height of the tire 10 is the width of the tire and the last number 8 is the rim size you need.

8x8 douglas or itp 8x8 or 8x8.5
