the last number in the tire size sequence is the rim diameter, for atvs and everything else metric or standard. the rims you have are 8 inch rims...9"wide by 8" diameter.
no, you have an 8" rim
those tires linked above are for a 9" rim like on banshees, warriors, rappy's and yfz's
those 9" rims can be fitted on our bikes with a set of those bikes rear hubs from ebay.
if you would like to upgrade to a 9" rim, like alot of us have, to open up tire choices,
braaaptor has a set for sale/trade right now..........
the rims im talking about are from a banshee i already did the banshee hub conversion on the rim it says 9x8.5at across from it, it says 10.00 they are the aluminum stocks from a warrior exact same i have on my warrior tires 22x11x9
