[QUOTE="JonFrum, post: 504688, member: 18044"] Drewed, It's [U]very[/U] unlikely the tire would blow. Normally trailers are raised up by shifters as they drive around the yard. Almost all the weight is on the rear tires. And as I said above, we use to have drop-frame ("W") pups that we jacked up about five feet into the air and left them unsuported by the shifter's 5th wheel. These pups held [U]more[/U] packages than a regular flat floor ("WW", "SC") pup and we never had a tire blow even though all the weight was on the rear tires. Same with jacked-up 40-foot "center-roller" trailers. The weight of the pup in question shifted to the front when the leg collapsed. What weight remained on the rear tires was shifted to the tires on the tilt side. Probably about the same weight as normal. Not enough to cause a blowout. Maybe someone who paid close attention in high school physics class:happy2: can explain to all of us in detail, how there is an imaginary diagonal line running inside the length of the trailer, from the left-rear to the front-right (assuming the front-right leg collapsed), and the trailer can't flip unless the center of gravity crosses over that line. I believe for the trailer to flip, the front-right corner would have to sink lower than the ground level. Maybe if coincidentally, there was a big, deep pothole under the spot where the corner landed, then the trailer could flip. But in the present case, the ground is holding the trailer corner up. I'd also like to see how low the other leg was. And if the collapsed leg was collapsed all the way. Also, if the contents were strapped in properly, the weight could shift, but only to a limited extent. Still plenty of weight on the left side to keep the vehicle from flipping. After all, the trailer sat for twenty minutes before the forklift drivers were even called. The pup, in fact, didn't flip. That reality should count for something.:happy2: [/QUOTE]
