Recommendations for replacing my Michelin LTX M&S tires

We've run on BFG AT tires for years. We carry a 3200 lbs Truck Camper, and often towed a 3200 lbs cargo/bike trailer. We've never had trouble in all those years. Well, shouldn't say never, one time had a glitch in one rear tire after a few years wear. BFG replaced two tires in rear, so we'd have same wear on both rear tires. BFG did in fact, deduct a bit for tire wear - but we were happy with that response.

We run LT285-70-R17E ... 75 lbs in rear, 70 lbs in front when loaded and hauling.
