The Nitto Ridge Grappler 35x12.50R20LT, Nitto part 217040, is a hybrid all terrain tire in a load range F, 12-ply rated construction with a 125Q load and speed rating. At 34.76 inches tall it is a true 35 inch class tire for 20 inch wheels, a size many Ram owners choose after a leveling kit or a mild lift.
The Ridge Grappler sits between a traditional all terrain and a mud terrain. The center of the tread uses a tighter, variable pitch pattern that keeps road noise down and wears evenly on the highway, while the shoulders carry big, staggered blocks and sidewall lugs that bite in mud, gravel and snow and protect the sidewall from rock cuts. For a Ram that is a daily driver during the week and a tow rig or trail truck on the weekend, that balance is the reason the Ridge Grappler is so popular.
The load range F rating matters on a heavy truck. It gives the tire the stiffness and load capacity to handle a 2500 or 3500 with a diesel up front and a trailer behind it, and it resists squirm when towing more than a lighter load range tire.
Specs
Fitting 35s on a Ram
On most Ram 1500s, a 35x12.50R20 needs a leveling kit or a small lift and may need minor trimming at full lock, depending on wheel offset. Heavy duty Rams have more room and often run this size with just a level. Check that your wheel width is within Nitto's approved rim range for this size.
Common questions
Is this tire loud on the highway? It is noticeably quieter than a full mud terrain because of the tighter center tread, though it is not as quiet as a highway tire.
Is it a load range E or F? The 217040 is load range F, 12-ply rated.
Will it fit my stock Ram 1500? Usually not without a leveling kit. Most owners level the front first.
