There will always be supporters and naysayers about anything that people do. The bands are just like insurance. You pay for them and hope you never use them. How many naysayers will advocate NOT buying insurance ? It will only take that one lightning bolt out of the blue to hit and you will be glad you bought them. How many folks here were glad the last time that they only had liability insurance when a rock broke their windshield, a load of water from the filling station ruined their injectors and caused a multi thousand dollar repair bill (yes you can turn water in fuel into your insurance company to get your fuel system replaced, always save your receipts for the last couple fuel stops)
We lost a tire on our truck due to another vehicle dropping a 5/8 diameter bolt and it lodged straight up and down. It poked a nice round hole straight through the steel bands. All but new tires, properly maintained with correct tire pressure ruined by a freak occurrence. Luckily I heard the tap tap of the bolt head hitting the pavement and then the whoosh when it flow out the air left the tire. I was heading for the side of the road and it was flat that quick.
There is no careful maintenance that can protect your tires from that odd bit of metal that is dropped on the road and wedges in a way that it will rip apart a tire. We have a section of highway that is frequented by scrap haulers and there have many times that there will be many vehicles all off to the side with flat tires.
That product will give you the time to get the unit off to the side of the road
safely. The only better arrangement I can see is those bands with a tire pressure monitor to give you an instant warning inside the tow vehicle that something has happened.
I ran some searches to see what you were talking about and there is a special tool that is needed besides the keyed wrench that is used for loosening the band. If you were not supplied the special tool that is used to depress the bead on a tire having the band removed, you should look into it.
This is the tool that should go with you. There is also the tool that loosens the bands. Without either, the old tire cannot be removed, nor a new one installed. Well actually you can cut the old tire off and simply remove the bands if you have that tool.
