I recently had Rugged Terrains installed on my Jeep. p265/60/18. I like the look and the ride is fairly smooth. I get a slight vibration in the steering wheel with them. Road noise is high, though. They claim to be quiet and all the reviews I read before buying them said they were quiet, but they're just about as loud as the AT/MT hybrid tires* I have on my Tacoma, and the Tacoma doesn't benefit from the cabin noise insulation the WK2 has.
The Rugged Terrains are fairly quiet below 20mph, then the noise ramps up as you go faster. Between 45 and 62 mph they sing in a loud drone that's hard to ignore. Over 62 they become fairly quiet again.
If I were cross-shopping the Rugged Terrain and the Firestone Destination A/T, I'd go with the firestone even though it's more expensive. I've run the firestones before and they're as quiet as a highway tire. I regret buying the BFGs because of the road noise.
