Im sure if you find the ID Tag for your machine under the seat on a Aluminum tag . I think it starts with a 917. number .
Then take that number to searspartsdirect.com and enter the numbers and down load the manual . It will tell you in the manual their.
Or Just look on the tire side wall . Maybe yours are marked on the inside of the tire . Example 16x9x10 , 18x8.5x9 .
If you have any trouble looking it up on the website post the tag number here.
Some one can help you out here for sure . :thThumbsU
I'm looking at a re2000 through pictures on line that has some oversized no traction ribbed tires on the back.
I google searched with no luck. Did a picture search, and couldn't find anything with enough detail to read the tire. I was hoping somebody might have one who could tell me...
