- Fitment: Make sure your vehicle can accommodate the 37-inch diameter and 13.5-inch width without rubbing, especially if you have suspension lifts or fender modifications.
Installation and Maintenance Tips
I had mine installed by a professional to ensure proper balancing and alignment. Regular rotations and maintaining correct tire pressure have kept the Ridge Grapplers performing well for me.
