Biggest All Terrain on Stock 2019 Tundra 4x4

285/60/R20 Toyo Open Country AT III

-They kept everything under the fenderwell. If just driving the road it would be fine. If going off-road you would have to eliminate the front mud flaps just in case you hit any ruts. You had about an inch when turning all the way left and all the way right between the front mudflaps, they did not rub or hit at all. If you eliminated the front mudflaps you would have all the room in the world and there would be no issue.


You ended up having about 4 inches between the top of the tire and the truck, plenty of room.

 

I ended up installing a 275/60/R20. Cooper Discoverer AT3 XLT.

Plenty of room, these are one size up that comes factory.
