So does Tire Warehouse. Though if you have a slow leak.... Once you mix air with the Nitrogen it don't much matter anymore.
Nitrogen that is bottled is usually dry. That would be one advantage to using it. N2 is also a larger molecule than O2. If they weren't so prone to massive changes in volume or state depending on temperature, I would like refrigerants for tire fill, because the molecules are relatively large and thus would leak less. In fact, the larger the molecule, the better, when it comes to filling tires and slowing any leaks or loss. However, some large-molecule gases also change their volume dramatically with temperature.
The only problem with sealant is that it gums up the TPM and makes it very difficult to clean out the tire.
The best tire sealant you can get is industrial/truck tire rated stuff that does not use water-softening fibers and I saw it used as a demonstration on a big truck tire with many big nails driven into it by anyone who came by the booth and wanted to give it a try. This seems like it may be the stuff:https://www.ride-on.com/us/support/tire-types/truck-formula
So, cars have tires. car tires have air. The truck-grade stuff has non-water-softening fibers, evidently. When I examined some truck-grade goop up close, the fibers seemed to be very fine aramid strands. Thus, I recommend it as being superior to other, more consumer-oriented tire sealers.
