These had great grip and were extremely rugged.

These tires have phenomenal traction and excellent wear! We used them all season, with heavy wear at 2 regionals + championships + IRI, and half a dozen one day off-seasons. We played into Saturday afternoon at all the competitions, but we used our twin for practice during the season, so it didn't see as much practice time. The only downsides...

They're extremely wide (in reality, they're about 3"+ at the hub)
They're quite heavy (~2 pounds each, I think)
They're 9"... good for some applications, not-so-good for many others!

We're looking at doing a 6WD this year so unsurprisingly we're looking for smaller wheels! :-) Thanks for all the links - I'm tempted by the 6" pneumatics from McMaster! Dropped center with roughtop or wedgetop tread on the corners, most likely...
