I used to run LTX's and they gave excellent service, better than any other tire I had ever used. Then the last two sets, one on my suv and the other on my 3/4 ton truck were so weather checked in three years that they looked like a tire that had set out in the sun for at least 20 years and both vehicles didn't see sunlight unless they were in use. I talked to two different tire dealers and both agreed that they were seeing early weathering and I quit them. Went to Cooper and Bridgestone. As old as these current Bridgestones on my jeep are, they show no sings of weather cracking. Our current suv which is fixing to have it's third birthday came with Michlins and they appear about like new so maybe Michlin fixed their problem. I'm still browsing tire dealers on the web looking for tire ratings but I consider real world experience from the members here more reliable.
I've had good luck with Yokohama Geolander AT's as well. Usually run Goodrich AT's but had to get these one year.
I rotate every 6,000 when I change oil. Got 80,000 miles from them on a 97 1/2ton Silverado.
Seems to me all of the AT/MT style tires get noisy at the end of life.
