mentions that a company called Bandag Inc has a card that 'grades' the cracking. I'll see if they have a downloadable version.

EDIT:

Sorry, I struck out. I can't find anything on that company & can't find anything on any gauges to determine severity of 'dry rot'.

On the funny side: I was helping a buddy of mine fix a tire on his (severely neglected) trailer. The dry rot was so bad that he had Fix-A-Flat coming out of the cracks. I was literally ROFL.
Here's a vid of the Bandag retread process...

I had almost forgot the time during my mis-spent yoot that I worked in a Bandag facility. They never let me do any of the cool stuff, like running the buffer, but I did work the tread cutting table for a while...ahhhh memories.

Thanks Tom...
