After looking at a couple of the boxes Saturday, I happened to think about something, and I’m sure there’s probably a good explanation for it. On the slide-out shelves that the cars sit on, the pickup rests in a slot and this keeps the front wheels off of the shelf by .5-1mm. This would keep the front tires from developing flat spots from extended time in the box, but I don’t remember seeing anything across the rear of the shelf that would support the rear of the car, taking the weight off of the rear wheels. This is just speculation on my part, but it seems like the rear wheels might be just as susceptible to flattening as the front. If the cars don’t stay in the box for extended periods and if that’s so, then this is a moot point, but the cars have to live somewhere all of the time. Just thinking through the keyboard.
