Edgar,
I apologize for JD. Sometimes we forget that the internet is worldwide and that folks can post form almost anywhere, especially if they have a question they don't have a good answer for.
I'm a engineer with a major tire manufacturer and I analyze failed tires, so I'm probably in the best position to help you.
Tires that have only be driven 50 miles will show just the barest amounts of wear (for obvious reasons). When tires are made, they are put in a mold. To prevent air from being trapped between the tire and the mold (which causes a defect), one method of prevent is to drill small holes through the mold, which in the finished tire look like little bit of hair sticking straight up - let's call these "vents".
Look at the tread surface and you should see the end of the vent - a small round bump. When a tire is new this vent should have distinct and sharp features, but as the tire wears, the vent will be worn off (becoming merely a round bump) before disappearing altogether.
So if the tire shows evidence of the vent, then this would be consistent with 50 miles operation.
If the tire does not show this, there may be another explanation. You didn't say what brand of tire, and there are several different approaches tothe venting problem, so you need to look at other tire of the same brand and type to see what techinque they may be using.
BUT - I think what you are saying is that there are no skid marks on the tires. This would be inconsistent unless the vehicle didn't slide or the brakes didn't lock up.
And that doesn't sound right (which is what I think JD was trying to say, but he went overboard)
It is still not clear if the tire came of the rim, or the rim came off the vehicle.
I suggest we move this discussion to another medium. I've sent you a private message, let's use that format.
Would anyone like to know the outcome when we finish the discussion?
