wolf rims are made of a thicker material - so a lot stronger, be careful as most are for tubed type tyres as there is no sealing ring for tubeless tyres. They also have a bit more offset. They are ideal for expedition / outback work as you can easily take a tyre off the rim to change the tube and it does not take as much pressure to reseat the tyre once tube is changed - hence the reason why military use them (strength also).
