Nitto Ridge Grappler
Choose the Nitto Ridge Grappler 37X12.50R17 LT 124Q D2 BSW, a hybrid terrain tire built for drivers who want aggressive off-road looks, capable dirt and gravel traction, and a quieter ride than many traditional mud-terrain tires. This 37X12.50R17 Ridge Grappler is a popular 37-inch flotation fitment for select Ram 1500 TRX, Toyota Tacoma, Jeep Wrangler, Jeep Gladiator, Ford Bronco, Ford F-150 Raptor models, plus similar trucks and SUVs using 17-inch wheels.
Why choose the Nitto Ridge Grappler in 37X12.50R17?
Built for lifted heavy-duty trucks, full-size off-road builds, and high-clearance custom rigs: The 124Q D2 rating gives this size light-truck strength for off-road use while keeping daily drivability in focus.
Hybrid terrain performance: The Ridge Grappler blends all-terrain road manners with mud-terrain-inspired bite for drivers who split time between pavement, job sites, trails, gravel roads, and weekend adventure.
Quiet, comfortable road manners: Nitto's hybrid tread design is engineered to reduce pattern noise while still giving the tire an aggressive stance on trucks, Jeeps, and SUVs.
Confident off-road traction: Alternating shoulder grooves, staggered shoulder lugs, and deep sidewall lugs help the tire grab loose terrain and add durability-minded sidewall presence.
Rugged truck styling: The Ridge Grappler gives daily-driven pickups and lifted builds a bold look without giving up the on-road usability many drivers need during the week.

So far, they perform well
This is my second set of these tires. I got 50k out of the first set & was very happy with the all around performance. Occasional off roading along with city/highway driving. These tires are quiet!
