A tall, narrower flotation format defines this 37x11.50R20LT Ridge Grappler. Nitto lists a 36.54-inch actual diameter, a 128Q service description and load range E, so plan clearance around the measured tire rather than the nominal 37-inch label.
- Alternating shoulder grooves, zig-zag lateral grooves and staggered shoulder lugs give this hybrid-terrain design its dirt-and-pavement character. Reinforced block foundations support the tread, and each sidewall has a different design.
- Exact version: 37x11.50R20LT 128Q E; Nitto part 218510. Overall diameter 36.54 in; inflated width 11.42 in; approved wheel-width range 7.5–10.0 in.
