Avalanche probly built the truck... Looks to me off hand like Michelin XML tires...could be wrong, but i think that's them... and my guess is Avalanche is using that truck to show of the new Trail Ready 20in beadlocks, which i believe are fairly recent, to come out... They list them as their own beadlock, but they're really Trail Ready rims... ALOT of their products come from other companies, but are rebadged, and upped price only to have the avalanche name...
