I was wondering if any one out there knew the stock size of the wheels on for a 400ex. I know that the tires are 20x10-9 and 22x7-10. But what are the rim sizes? 9x what? and 10x what? I am asking this cause I would like to get a set of sand tires and because I know that it works, I would like to stick as close to the factory size as possible. (But I refuse to pay the $100 per wheel from Honda!) Also if any one knows of a place that sells tire and wheel combs kinda cheep, please let me know. THANKS!

 

try this place www.tiresnstuff.com or www.rockymountianatv.com
they both have lots of kits avalible on tires sizes
your rear wheels are 9" tall and around 9" wide and the fronts
are 10" tall and about 6" wide
you can get some nice ITP or Dougles wheels cheaper that stock and
they're nicer wheels

 

The size is stamped on the OEM rims. Just find a bike and it's right there. (Sorry, I can't go look for you, none of my bikes have stock rims.)

I use ITP rims. 9X9 rear/10X5 front. They are wider than stock or Douglas, and have a deeper offset, so it makes the bike 3" wider in back, and 2" wider in front. Some nice added stability!

On the other hand, if you want cheap, light rims for the sand, get Douglas Blue Label. But, not if you are going to bust out any big air, because they will bend.
