Though the best way to fix a puncture is to patch a tire, this isn't always possible when a problem occurs. Tire patching requires the removal of the tire from the rim, which typically can only be done at a tire shop. When you have a flat and are without a spare tire, tire sealant may help you get back on the road until you can find a more permanent solution. Tire sealant can also be used as a preventative solution, and is safe for use on tires equipped with TPMS. If you need a quick fix for a flat tire, shop O'Reilly Auto Parts. We carry a variety of convenient tire sealant options.
