Doing a little juggling between tires to find the best ride for the Expedition. I went back to the Marathon Plus 20x1.75 (47/406) tires after opting for a little softer ride. After a couple rides I've decided the 47/406's are the best fit for the Expedition. There's no need to try and make the Expedition a little faster and sacrifice comfort when I have the 700 for those times when speed is a priority.
Here's my original posts regarding the new tires.
