Yes it is ok to put air in especially if the can leaves you at a lower than specified pressure and you have a ways to go before you can get it repaired But remember Fix-a-flat is not a correct fix. It does help in emergencies. you should have the tire repaired,or replaced. With Fix-a-Flat, a tire will be unbalanced and will be shorting the life & safety of the tire.However, you should inform the tech who replaces or repairs your tire that it was filled w/ sealant as some brands use a propellant that is flammable.
