Re: 40\" IROK tires
The Tread depth is 22/32 on these tires and a comparable sized Swamper is 25/32 so the difference is 3/32
The outer lugs are scooped like a bogger, so at first glance, they should do good in mud, but allow excellent lateral traction. So, in mud Ideally, they should do better than a Swamper. This is my speculation - we will see this weekend. /forums/images/graemlins/thumb.gif
