400ex, and 450r wheel bolt pattern?

[RH1N08d9]

Hey guys, I have a ex now, but it's gonna be gone soon, with a 450r in it's place. I want some front sand tires for our next trip to little sahara, but I'm not gonna have a 450 by then. I'm like 99% sure that the bolt patterns for the wheels are the same, but I want to be 100% sure, before I buy some new tires and wheels. so anyone that knows for sure, please chime in!
later,
ryan
