I felt a huge difference in ride quality going from my OE tires to Michelin Defenders.

I purchased mine here: https://www.etrailer.com/search/sumospringsDo you have the model number for the sumo springs?
Update on my Expy max 22” no CCD. Swapped out the Pirelli’s for LTX and made slight improvement. While the tires were off could tell both driver side struts were leaking. Took into dealer and they had to order all 4 corners (4 week backorder). Finally got em installed and back on the road. Still a very stiff ride. Wish would’ve tried the Billsteins, but wanted to try OEM since mine were shot.Thanks for the info. Dealer says my struts are fine. Visually no oil and they aren’t locked up. Going to get them checked out again next time in for an oil change. Thinking about trying out some new Michelin after reading comments on this thread and looking at at other threads
My Michelin Defender 22" tires are smooth as glass with CCD and stock shocks. The ride on smooth, bumpy, pretty much any road is flawless.I like the floaty ride of the ccd. I do think the sport setting feels real good, just can’t take the trans shifting. I test drove a standard suspension one and it was quite a bit firmer in the ride, less bouncy after a pothole. It’s like the ccd lets the bumps shake out longer so not as harsh, but some don’t like how that feels. Preference is what it boils down to.
bilsteins are a nice product. I’ve had them on an f350. I plan to go to them on my hobby car next.
these are the worst oem tires I’ve ever dealt with. They flat spot easy, and I can feel them getting worse as they age through vibrations in the steering wheel. I was particularly bummed this summer when a trailer blew a tire in front of me and I got a bolt in a tire. Best option was a new hankrook at the dealer. It made the wheel vibrate noticeably less. I can’t wait to change these. I had a skid on a road I’ve been on a bunch of times in the second year when it was light raining. Never had that happen before. They ride funny at times, depends on the weather. They feel like they have low traction in the rain period. They struggle when towing, have to air way up. Have to watch the psi gain as they get hot, they get greasy feeling when they go over 50, which can Happen as the day gets hotter.
I concur. The base shocks hit harder on most bumps and seams, but are more comfortable on city streets becuz the ccd allows too much tire slap and motion in any mode but sport. Its worlds better on the hwy though. The air springs work beautifully in the pre refresh 3rd gens, idk why ford did away with them, especially since the 4th gens are notorious for eatin up shocks anyway so the air spring maintenance in a mute point. My 4th gen nav rides better than my 3rd gen holistically, but the 3rd gen handled bumps better esp repeated bumps.My Michelin Defender 22" tires are smooth as glass with CCD and stock shocks. The ride on smooth, bumpy, pretty much any road is flawless.
Regarding Trans shifting, reset your PCM so everything learns again. I did mine, because I bought it used, and it was jumping gears going from 2 to 5 or 6, jerking when slowing down. Now my Expedition shifts flawlessly and learned my driving habits.
This is especially important if there ae multiple drivers. I mostly do slow takeoffs, coast to traffic lights and use cruise control highway and local.
It's been months now since the reset and mine is still shifting smooth.
