True, it will all freeze at some point. Most pre-mix RV antifreezes freeze at a surprisingly high point, around 10deg , but it actually protects against expanding and bursting to -50.all af mixes eventually freeze.
the misnomer is that it is actually holding tank AF.. etc.
It generally is used in RV fresh water supply systems, it could be used in holding tanks, most RVers drain them for winter storage.
In my area it would be extremely rare to see 10F (even saw 0F once) so it would work fine in tires, not so sure in much colder areas.
