America's Tire Co and Discount Tire Co say that they will fix a flat tire for free they will even rotate all four tires for free. As far as I know there is no catch, they have always done this.
Yes.
yes but you have to have a kit or at least a tire patch
Fix a flat, you can get it at any dollar general store or Wal-mart.
You cannot drive very fast with a fix-a-flat sealant in the tire. The exact speed depends on the weight of the car.
Yes .
Fix-a-Flat kits work on a very temporary basis. A punctured tire should be replaced.
No, and if you used it already no tire place will repair the tire in the conventional way.
You should buy a new tire and save the fix-a-flat for your bike.
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.
It says on the back of the can not to use it on those tires.
Cars that use run-flat tires don't have a spare tire. But there's no other reason you can't switch to regular tires. Best thing to do is learn how to plug a nail hole and carry a can of fix-a-flat or a small compressed air cylinder that you can use to re-inflate the tire should you encounter a flat. Or if you have CAA or AAA you can call and have them fix it.
The first thing to do is pull over immediately in a safe place if you are driving. You should then get out your car jack and spare tire and change the flat. It's always good to keep a can of Fix A Flat with you also for quick fixes.
