A full mud-terrain tire from Nitto. This particular size is meant to pair with a larger lift (6 inches or more) rather than a stock-height truck or a smaller leveling kit.
why this one — If you've already got a significant lift and want maximum off-road traction and an aggressive look to match, the Trail Grappler is built for that bigger-tire setup.
Fitment-driven category, no power claims. Spec: 37x12.50R17 (Load Range D) - the requested 37x13.50R17 size could not be confirmed as an actual production size.

None directly, but changing tire diameter shifts speedometer/odometer accuracy - a tune or gear/calibration adjustment is recommended for large size changes (e.g. 33in to 35in+).
