2011 Pro-4X. Will be used street, mountain highway, mountain winters, and trails (not rock crawling, not lifted, no winch).
BFG All-Terrain T/A (KO2) came on it when I bought it in July. They seem nearly new. One has evidently had an internal separation and I'm advised to change out at least two, keeping the matching tires on the same axle. I feel like they have performed well on both rocky and deep sand trails. Only a little mud, but nothing scary happened on those bits. They seem noisy and vehicle highway handling is maybe not the best, but I have no basis of comparison. They are an LT tire with a E load rating and 10-plies. They do not meet the speed rating specification, but I really can't see this is relevant.... I'm not going over 106 mph in the Xterra.
Tire Rack suggests Cooper AT3 4S, among others. While both tires are considered all-terrain, they seem considerably different to me. The Cooper's are described as
Both tires have the mountain snowflake emblem. I guess my expectation is that the AT3 4S might have a bit better street manners. Possibly quieter and a little better handling. If I went with these, I'd probably change out all 4. That would be welcome, but would I be giving up much performance on the trails?
I usually air down to about 32 psi (measured on a hot tire, generally reading about 39-40 psi before airing down) on trails, and air back up to 39 psi (also measured hot) when returning to the street. When I recheck them cold they are generally within 1 lbs of the specified 35 psi.
Your thoughts?

The internal construction of the Discoverer AT34Sconsists of a durable, two-ply polyester casing. A single-ply, nylon reinforcement above two high-strength steel belts further increases durability and handling response, along with providing high-speed stability.
