I damaged a toyo tire on my tow truck while pulling a trailer. I ran over something on the road that put a 1in crack near the tread on the side wall....due to the size I was running, no one had one on the road. I monitered it at every fuel stop on the road, while towing home (over 1k miles). the crack went to 1.5 inches and never lost air.
i ran toyo muds on my jeep, and on 3 diesel trucks, I have not had a flat or any balance issues on there mud or at tires.
Toyo's have been great for me. and I continually run them. my current "desert truck" is a ford f-250 and I'm running the new toyo at2. supposed to have a lil more tread life at 50K or 60K miles.
