Blast,

Based on your requirements I think you would do well with a light truck Highway all season radial, like Michelin LTX M/S (Highway All-Season). These get good mileage, run reasonably quietly, last a long time and have good performance in light mud and light snow conditions. I wouldn't try driving in mud up to my axle with these, or take on snow up to my bumper but they will more than cover the needs you describe.

These run about $100-$120 per corner depending on sales etc. Bridgestone Dueler H/L Alenza run a bit cheaper most of the time and are very similar in overall capability.

I have never had any problems with either of these tires on my wife's SUV. I put the Michelin LTX A/T 2 on my Jeep since I tend to drive it in snow conditions that more reasonable people avoid.
