I'm a little surprised by the MPG loss reports-harder rubber, less sidewall flexing, less rubber on the road (with any load at all) should mean less heat & less fuel consumption. Unless we're comparing mud tires to all-season P metric, I'm not getting it.
In my case that I referenced, the LT tire I choose is a somewhat mild tread A/T, and 12 lbs heavier than the OEM all-season P-metric. The difference in weight is definitely a factor.
The new tires are vastly better in the wet, snow, and 4wd trails. Obviously they'd be lacking in deep mud. But in some moderate mud they did fine. On-road they are nearly as quiet as the OEM tires. They're just a better all-around tire for an SUV that doesn't see only dry pavement.
