Bent rim

[BamBam730]

You will see by the picture below why I am asking what is the exact size and bolt pattern for a rear rim on a 2007 ds650X? This rim came stock with outer ring but no inner ring. I was riding hard and bent it. The other rear rim also bent, so I am looking for a new set of rims and tires that will hold up. I know my currrent rears are 20X10X9. The itp rims i was looking at are 9X9, where am I losing the inch, the width?
Any suggestions, I am not looking to loose any size on the tire. I was wondering if the rim comes smaller by an inch (9X9), but the tire is still a 20X10X9, is it by design creating a tighter bead on it

9x9 is a standard size 9" wheel, your tire is 1" wider, you can get tires that are 11" wide as well and fit on the 9x9 wheel.

I am not sure of the bolt pattern on the DS650 though.

Thanks for the advice. I bought Holeshot HD 20x11x9 on Douglas .190 rims 9x9. Hopefully these wil stand up to being ridden hard.
