To 40 series or not to 40 series, that is the question

Picking a good strong set of tires, and following the thread I suggested for building beadlock wheels should get you over the hump. I even use a little thin layer of double sided tape under the metal ring to help keep the tire bead from slipping out of the rim. If you build them correctly they will hold up just fine.
