This is how I did it when I had problems with my shoes and the sensor not activating. I used small foam feets for furniture to create pressure points.

@blackswan it's sad that FM isn't clearer about lithium battery care. They deliver the OW with a safe storage charge, so they understand the importance of lithium battery care, but they could do more to educate or even build in some smarts with the charger to drop the voltage to a safe storage voltage if the OW is left plugged in for an extended period of time.
I get the Pint tire bump too. My Pint is 18 months old so there is no warranty. First of all... Love my Pint. I carve and ride both directions. Almost all of the bump is on my switch side, probably because I ride that way 90% of the time and also in the 30-50degree F range during our winter. I think I was making too many tight turns with 17psi. I weigh about 250lb. I've raised the pressure and it is a little better. I am looking to get a new tire. I like the suggestion I've seen on another forum that I need to ride in the heat for a while... We'll see what happens. Almost 500 miles on the tire. Lots of turning... 67 years old and stoked.
@bgood420 it's not clear cut if the board deactivated due to both sensors not detecting or deactivated due to the BMS shutting off power. The sensor alarm may have occurred minutes before the nosedive.
How to milk crate: Write a support ticket to inform @Future-Motion about the issue. Take a sturdy box or milk crate and perch the board up evenly without the wheel touching the ground, then place something on it that's heavy enough to activate the sensor pads up front. Document the procedure with video and take screenshots of app on your phone to show FM customer service when they finally respond. Let the board use up all it's reserve power by running the wheel until it shuts off. Send a diagnostic report via the app after the board powers down (you may need to restart the board). Once finished, then you charge it for 24-72 hrs uninterrupted. The board appears to cycle charging operations. You may notice it on a long deep charge because your board will appear to turn on by itself while charging. This procedure is not intended to be done often or regularly as it will prematurely age the battery if you consistently run your battery down so completely.
The ideal solution for @NotSure above would be that if the board were in "slow mode" (under 1 mph or whatever that limit is) along with simple stop turned on, then either pad would allow the board to continue operating. In this mode, higher speeds would not be affected, keeping the high speed nosedive protection intact. It could also be a sub option under simple stop so it could be set separately if desired.
That said, this would require @Future-Motion to make a software change in the app and on the board, which I wouldn't hold my breath for as the only changes they seem to make are to the leader board features. I (and MANY others) have been asking for a configurable speed notification for YEARS, but such things don't get their attention (I've even suggested this on the phone with them, only to be told they would suggest it to the devs). It also assumes that @Future-Motion even looks at this board (which we all know they don't).
I agree with most responders above that making a wiring change to affect this would be a dangerous mistake, but then that's just IMO, as I have no need for such a feature. :)
Thank you, Lia. For me, the sound only appears after I have been riding the board to the point where the battery has been depleted to 4% charge or less. And even then, it doesn't appear every time that I drain the battery that much.
@RickN Agreed, with battery health you usually end up with diminishing returns. At a certain point you spend more time trying to give your battery that extra mAh lifespan than using the device.
A problem with never going above 80% is the BMS can't balance the cells since almost all BMS's I've seen do a balance at 100% over a long period depending on how out the cells are form each other. Without a balance charge cells can get so far out from each other that the margin of usable capacity shrinks quicker than any cell degradation ever could.
It's a science and most after looking deeper into it accept it's not worth religiously maintaining. For the OW my rules are simply if I can ride the next day on what charge I have leftover don't charge the board, if I plan on riding far the next day do a balance charge overnight.
@nemo801 the charger does what's called a top balance. I.e. charges cells to the top of the voltage range.
Draining the battery by running it flat in a milk crate or similar does what's called a bottom balance (bottom of the voltage range). Don't do bottom balancing too often but it might help in this case.
If the bottom balance doesn't fix it, a cell is dying and you should pursue a replacement battery under warranty.
@stinkyface Correct. I have only had the board a month. The board is still stock. I called last night after work (5 est). FM rep apologized and said they were looking at my ticket and would get right back to me. I have not heard back yet.
