Flat Free is guaranteed not to void manufacturers warranties on tires, and we have the letters to prove it. Unlike some other products, Flat Free does not chemically interact with the rubber of the tire, so it cannot cause damage.

Copies of letters sent to American Sealant International, Inc. from major tire companies are on file at our offices and available online in PDF format (207K).
