What is the measurment for the rims size on a 400EX

[BornOnFire]

I am going to buy some tires and rims from a friend and I am not sure that they will fit a 400Ex. Can anyone help me on this? Heres the pic that the seller sent me. What do you think people?

The diagonal distance should be 110 mm. That is a little more than 4 1/2".

Thanks for the reply. That seems to work based on the pic. Hopefully, it will be a good purchase!

Gee, that's great advice!:huh

110 mm is the bolt circle. that is 4.33 inches measured diag across opposite side holes from center of hole to center of hole.

tell me what quad they were off of and i can tell u if they will work. I have all the books here!

And if we remember what we learned in algebra, any three bolts will form an isosceles triangle with the diagonal dimension being the hypotenuse.

Therefore the distance between the adjacent bolts is

110mm / Sqrt.2 or 110/1.414 or 77.78mm.
