I've been on Nitto Terra Grappler 285/65/R18 and they've been good tires for me and quiet, not as aggressive as the Ridge Grapplers. I recently upgraded my wheels and went to 295/70/R17 Toyo Open Country R/T Trails. They're aggressive but not as loud as the Ridge Grapplers and I'm very happy with them. From what I'm hearing from friends and reading they're going to be a more popular option than the Ridges, they also come with a 45,000 mile warranty.
