Nitto Tire Trail Grappler 315/80-17

The Nitto Trail Grappler 315/80R17, the metric version of a 37x12.50R17, is a mud-terrain built for lifted Jeeps and trucks on 17 inch wheels that spend real time off pavement. The tall sidewall gives you room to air down for traction and protects your wheels on rocks.

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 315/80R17, this is a load range D light truck tire with a 124 load index, rated for 3,525 lb per tire, and a deep 21/32 inch tread. A 37 inch tire on a Jeep Wrangler or Gladiator usually needs at least a 2.5 to 3.5 inch lift and fender or flare work, and full size trucks typically need a 4 to 6 inch lift.
