yeah i imagine a whole lot of preventive repairs have gone by the wayside due to the recession,, thereby putting the motoring public in danger !!! the d.o.t. needs to step up its enforcement now more than ever,, as truck tires don't suddenly blow out,, unless overloaded, or damaged previously,, or underinflated.. so the driver didn't do his job properly & chose to operate an unsafe vehicle !!! drove em for 40 years & never had a problem,, wasn't right,, it didn't move till it was !!!simple !!!
