I'm not familiar with this particular product, but their site seems to read like a Fix-A-Flat can. I guess I can't speak for the heavy truck industry, but for light auto use that stuff is nasty. I'm not saying it doesn't work, but I'd have to be REALLY desperate (like middle of the desert with help days away) to use it.
It will throw your wheel tire assembly out of balance while it's in there. When you go to have the tire fixed properly, the entire interior surface of the tire will have to be cleaned of this product. And it is a nasty, sticky, difficult product to remove. Then you have to get it off the rim too. And believe me; you are billed for every minute the shop spends with rags, cleaners and scrapers getting this snot off your wheel and tire. Left to dry too long, it hardens, and is nearly impossible to remove.
So if you can call for help getting the spare on, or for roadside repair, I'd go that route. If the wolves are at your car door, and you must get moving again, no matter the cost, then I guess it's OK.
