I'm running the speedmax 32s on my trainer/beater/road bike. The downside I didn't see mentioned is that the edge blocks that give you good cornering in dirt make them a bit squirmy on fast paved corners.

I think they're good up to 110psi. Enough that it really doesn't matter.

Mounting wasn't a problem for me. Your mileage may differ, depending on the rim.

I can pretty heartily recommend them for anything except racing in mud.
