We assumed that the engineering rebuild order would have specified a tire swap, so when we interviewed Dave Welday he gave us the opinion that the tires were simply crayon marked because the engineering rebuild order would have had a an approved tire substitution for track use directly from Chevrolet engineering-- But as we can see that's exactly what happened going from D all the way to E, the label on the spare shows that the tires were sourced locally from a tire dealer in Speedway Indiana...

Now looking at the comparisons look at the size difference on the sidewall size from #92 to the tires used on the rest of the firestone equipped cars...that's exactly what happened. Thanks Charley
