08. The key to this truck's appearance and performance was its Michelin tires. We wanted to do something way different than the standard 35-inchers, so after considerable research, we found these Michelin XMLs in a 395/85R20 size. The XML is a military tire with a G load range (that's 9,645 pounds per tire at 95 psi). These tires are also offered in a 14.00R20 (49.5x15.1) size and 12.00R20 (44.5x12.2) for 20-inch wheels, and 325/85R16 (38.7x12.9) for a 16-inch wheel. There's a slightly less aggressive XZL also available.
