On heavy equipment (Graders,Loaders,Articulated Dumptrucks) they seem to hold up well; as long as you don’t have to do flat repairs.....as the rubber seems to have more oil in it & when buffing down inner liner to patch-can be very thin & close to the cords.
The large radial’s (14R24,17.5R25,23.5R25) tend to hold a good plug repair.
It’s weird how large equipment these days will come with Chinese tires & we ship Michelin Tire’s to China....ballpark cost is 50% less for the Chinese Tires.
I install what my company buys & they hold up well,,,as long as they don’t start getting “Holed”.
