40-55 mph pulse vibration

[Berky]

Hello,
I recently bought a used 2022 Explorer ST with 57K miles. Had it 2 months and I’m noticing an odd pulse or cabin vibration between 40-55mph. It comes in a wave or frequency. Most apparent with light throttle and decelerating. Only in that window of speed and it’s irritating. I have an appointment at ford in a few days, but I’m looking for some insight from members here. I don’t think it’s tires as a shift to neutral while under speed seems to calm the vibration. Sport mode doesn’t seem to do it or not as bad. It’s almost an ear pressure issue as well. Very Strange, but hard to describe. Anyone had this and had resolved? Any input would be appreciated. Thank you

Any chance you're still running to OEM tires? The foam inside the tires tend to come loose and cause a vibration a certain speeds. I replaced my tires due to low tread and the vibration went away.

Hello, The tires are Michelin primacy tour a/s. Not OEM and lots of meat left unfortunately (Walmart tire). They like to be run above 40psi and that makes the ride rough. I’ve played with tire pressure and it’s not the issue. Can’t wait to swap them out. Thanks for the reply

Confirmed: This issue disappears in sport mode. The whole cabin sound is quieter. Weird. Just obnoxious hard down shifts lol
