Another vote for the Michelin Defender LTX M/S, which may now be replaced with Michelin Defender LTX M/S2. We have them in 20" on both our 2017 and 2011 Expeditions. They are good handling, low road noise, long lasting and surprisingly good in bad weather considering the non-aggressive tread pattern.
Michelin is constantly changing this tire along with very slight changes to the name, which makes it very confusing and important you look at the actual Michelin part number and specs on the tire you are actually purchasing at the time of purchase.
Jul 2013 I purchased these tires for my 2011 Expedition.

April 2022 I purchased these tires for my 2017 Expedition.

Dec 2022 I purchased these tires for my 2011 Expedition.

It appears that the tires I purchased in 2022 are now being replaced with Michelin Defender LTX M/S2, which is not the same as the M/S 2 tire I purchased in 2013. This current tire is rated 117T 820 B A, load range XL / 2833lbs and max pressure of 50psi, so it appears to have some definite improvements over what I currently have installed, especially for towing.
