I recently had a blowout with a BFG LongTrail, which might
have been due to low air pressure. Don't really know for sure, but I'm now more aware of tire pressures.
My take on this is to air up for safety instead of a good soft
ride. Check the max psi allowed on the sidewall, and air up
accordingly. I don't go under 32-33 psi on any tire anymore...
