I'm about to pull the trigger on one of these. I've done a ton of browsing and such but I can't find much info on the Ridge Grapplers ( $293 each ). The STT Pro are well reviewed and rated and cheaper ( $253 each ). BUT! The STT Pro seem to lack a bit of aggressive side wall design. It's a bit "flat" for a mud. I had Toyo AT2 ( for example ) and unless you go with their "extreme" sizes. You get a very flat sidewall. Same design, just flat. I'm worried the Ridge Grapplers would do the same thing and offer a nice desirable design but flatten it. Anyone have any experience with the Ridge Grappler or have an answer about the flatted sidewall blocks? Or should I save some $$ and get the STT Pro. The price difference is basically an alignment which I need. Edit: I'd also consider a 285/75r18 Toyo RT. Those are a bit further up in price but if anyone has any experience with those please leave a comment!
