I know what the tire size is but what is the stock rim sizes on a 2007 honda 400 ex.I just picked up a set of itp hole shot xcr tires that are almost new.back are 20x10x9 and front are 21x7x10.I want to order some of the new itp ss rims for these tires to fit on my 400.So what size rims are stock or what size should i get in the rims for the front and back.

 

So know one can tell me the stock rim size or the proper rim size to buy for my tires.

 

For the rear you need 9x8, honda pattern which is 4x110 can't answer about the fronts never bought any, where ever you get the rims from will know.
