BK, if you had handled the bus poorly & wrecked it, they would have learned what terror really is!
There is scary & then there is real terror - hard to know the difference until you are unfortunate enough to experience the real deal.
Safe roads to all
It is very likely the extra steer axle will increase stability in the event one tire fails.
FWIW, it has been my experience (after 3 or 4 front tire blowouts) that the driver's response has the most influence on the level terror experienced.
Over correcting or slamming on the brakes = more terror.
Kyle, 56 passengers and a huge bang like a 10 gauge shoot gun going off in the bus = terror ~ regardless how smooth the driver handles it and brings it to a stop! Speaking from experience BTDT!
