Glad everyone is OK---that can get scary real quick
I once had a set of duals pass me---I watched as they jumped the curb and sailed through the picture window of a Chevy dealership. I've never full understood the physics of how the duals sped up to pass me It may be that I saw it happen and slowed down--I'm not sure.
Luckily this happened early one Sunday morning and no one was on the sidewalk or in the dealership. I'd guess the weight to be about 400-500 lbs for two tires, split rims, and hub assembly.
The alarm went off so the police showed up right away. After I gave them all my information, I chained up the axle, and continued on my way. That trailer had a "walking beam" suspension on it so, even loaded I could hobble to the next job on the three reaming duals.
I went back on Monday and recovered my duals
