36 / 13.50" - 15" bias ply Iroc's , no attempt has been made at balancing them .
These are on 15" x 10" beadlocks so I can air WAAAY down.
Great tire , I haven't tested them in mud yet , just winter conditions.
Yup , they flat spot overnight , and shake a bit , a very slight shimmy but nothing scary. I knew all of this before buying so have no buyer remorse.
