Pick up extra cargo space by removing styrofoam shipping carrier under the floor of the cargo area

Yes you are right about the tires. While they aren't the noisiest tires out there, they aren't the quietest either. The issue with any XL (extra load range) tire is they are noisier than standard tires because of how they are made with the extra stiff reinforcement. Manufactures are aware of this and in many of the XL range tires, they have added foam to the inside of the tire to quite them down. Many Tesla's have tires with sound deadening like Continental Conti-Silent and Michelin Acoustic tires. The only Mach-E to have acoustically quieter tires is the GT/PE which have Pirelli P-Zero Elect PNCS (Pirelli Noise Cancelling System) tires. When I changed out the tires on my Mach-E for larger ones I looked for this but Michelin did not have an acoustic tire in the size I wanted.

Since most the noise does come from the tires, it would be a good idea to try to get quieter tires if you are after less road noise. Next could sound deaden all four wheel wells but the rear is more important since the front wheel wheels are really not part of the interior of the car like the rears are. Also deadening the doors is good too a lot of the road noise comes through those doors. Again, the Mach-E is very well insulated from noise as it is so quieter tires would probably be your best bet.

I use products like Dynamat (rubber butyl type material) that is sticky on one side and has foil on the other. This will deaden all metal panels to a low thud when tapped and is a good insulator of temperature too. Then on top of that I apply Dynaliner (1/4" closed cell foam) to reduce certain frequencies and it will make a door interior or wheel well very dead sounding (no echo). There are many manufactures that make similar products so not like you need to get either of these two.

I normally take photos while I am deadening a car but actually took very few of the Mach-E. Kind of done taking photos as I work now. In the first photo below is the cargo area. After removing the hard carpet liner, it was all bare metal. I applied Dynamat on most of the metal areas then on top of it, the Dynaliner foam. I usually apply slightly larger pieces of the foam so that is why you don't really see the Dynamat material because it is underneath. I would normally do this on the floor and roof of the car but it is not necessary on the Mach-E (unless you don't have a glass roof). Did the same thing in the rear quarter panels and all four doors. The second photo shows the full hard plastic window regulator that does a decent job of sealing out noise from the outer door skin. I still took it off and lined the entire inner side of the outer door skin.

How do you fit pieces back together (such as carpeting cut to fit) when you’re changing dimensions by more than 1/4”? If you. Impress the material you’re adding, doesn’t that ruin the audio properties you’re trying to achieve?

If you remove the Styrofoam shipping carrier under the floor of the cargo area you can pick up quite a bit more hidden storage space.

I removed the styrofoam piece and the room that is gained is not that great to me. I have the tire inflator back there with an emergency light, first aid kit and road hazard kit which fit nicely in the styrofoam section where the Mobile Charger was (and they don't roll around making noise). With the stryrofoam removed there was a slight increase in room but not that much. I was hoping that my emergency blanket would fit there but no luck (it is currently in the frunk). I ended up putting the styrofoam insert back. I also noticed that it supports the floor of the storage area when it is replaced.

The Dynamat material is very thin and the Dynapad foam I use on top is 1/8” when I’m installing it under carpet or headliners. I use the 1/4” foam in doors and more open areas.

I’m assuming you have the cargo floor in the lower position since you said the foam insert supports your floor. If you kept it in the upper position there should be enough room for your blanket in that deep well and there’s plenty of room to still put the tire inflator and charger cords back behind it like where mine are. I put Velcro on the bottom of the tire inflator so it won’t slide around on the lower carpet.

Cool! Got it!

You're right, I keep the floor in the lower position. I can see where there would be more room in the upper position. Which position does one put the floor to match the height of the folded down back seats? I don't keep the Ford Mobile charger in the car as I use it to charge the car and its on the wall in the garage. Also I purchased a firmer case from Ford for it (Mobile Charger) and I'm not sure it would fit back there. It's in the frunk now with the blanket.
It would be nice to free up the frunk however. Is there any disadvantage of keeping the floor in the upper position? Does it rattle more in that position?

I don’t get any rattles from the floor in the upper position and I have a 12” sub under there so I think you are fine.

There is another post about weight limits but i believe it was 300 lbs in upper and 700 lbs in lower position. The upper also is for laying the back seats flat. I also believe the interior protection mat is designed for the lower bracket.

Upper...ALL of your questions could be answered within 1-5 minutes by trying things out for yourself.

I'll be doing this over the weekend. I just realized, thanks to this forum, that my rear floor was in the top position. Explains the 'thwomp' I'd hear from time to time. I'm currently hunting for a write up on how to get to the rear wheel well area without gutting the seats etc.

I didn't remove any seats. I pulled away the rear part of the cargo trim panels reached in behind and applied the sound deadening (dynamat and dynapad).
