The Oracle 32" comes with a scaled down version of the 36" Nightrider tyre, so it's good for on-road and off-road applications.

A 32" wheel may seem like an odd size, but it fits nicely between the 29" and 36". This is a great size for anyone who isn't comfortable on a 36" but still wants to clock up some distance both on-road and off-road, or as a great compromise if you can't have both 29 and 36" Unicycles.
