These are actually Ecsta 4X 245/45/ZR18 W100XL tires, not listed as a choice, but have the same tread pattern as the Ecsta LX tires. About 1000 times better than the BF Goodrich tires that they replaced, my wife no longer takes our F350 to work when it has snowed or snow is forecast. Tires are quiet and have been in use for 2000 KMs, thru one snowfall and wet and slush from melting snow (live in Calgary in Canada where Chinooks can give you every condition in a day). Listed treadwear as average as only been on the car for 2000 KM (too soon to say anything about it). Have been driving about 80,000 KMs a year for the last 45 years and these are one of the top tires I have used and reasonably priced.
Second worst tires I have ever encountered, only second worst to the old Firestone 500s. Poor traction in all conditions, dangerous in the winter, extremely noisy. Kept them on the car until I wore them out at 60,000 KM. When removed all 4 had a split on the inside rubber sidewall that went almost entirely around the tire. I never rotated them as I was not interested and making them last any longer than I had to.
