Toyo Open Country M/T
Toyo's MT is a classic aggressive mud-terrain — heavy, loud, but tough as nails and straightforward to find.

The Toyo Open Country M/T is one of the longest-running MT tires on the market. Big aggressive lugs, very stiff sidewall (3-ply), and a deserved reputation for being nearly indestructible at the cost of weight and noise. Common XJ sizes: 33x12.50R15, 35x12.50R15.
It's a popular choice on rock-crawler builds where the truck doesn't see much highway. Tread wear is poor on pavement (28k–35k typical with mixed use), and the rubber gets hard in cold weather. Not severe-snow rated.
