My opinions...
Goodyear Silent Armor - Quite, wear well, don't stay balanced well and have developed an out of round pattern to 3 of the 4 tires, tough sidewalls, significant drop in MPG...
BFG - Relatively quite, wear well - but not as good as the GY, stay balanced easily, good rock/dirt traction, poor mud traction, durable sidewalls
LTX AT - Ran 70k on these w/ no balancing issues, reasonably quite as long as they were kept rotated, durable, great tire...
REVO - Good All-Around Tire, reasonable quite as long as they were kept rotated, not as durable on the sidewall or tread
LTX AT/2 - I have these ordered for a new truck... Hope they hold up as well as the first ones did...
