The Nitto Trail Grappler 395/65R20, the metric version of a 40x15.50R20, is a 40 inch mud-terrain for heavily lifted trucks and dedicated off road builds. It delivers maximum ground clearance and a huge footprint with a tread that is still civil enough to drive on the street.
The Trail Grappler uses large, staggered shoulder lugs and deep voids that dig into mud and clean out fast. Nitto engineered the tread with variable pitch blocks to cut down the road noise most mud tires make, so the drive to the trailhead stays livable, and the sidewalls carry their own tread pattern for added traction and puncture protection when you air down.
In 395/65R20, the Trail Grappler carries a 128 load index, rated for 3,970 lb per tire, with a deep 21/32 inch tread. A 40 inch tire usually needs a 6 inch or larger lift on a full size truck plus trimming, and re-gearing is strongly recommended. This size calls for a wide wheel, 11 to 14 inches.
