Frequently Asked Questions
Can aerosol inflators like Fix-A-Flat permanently fix a flat?
No. Aerosol inflators are intended as temporary roadside fixes to seal small tread punctures and restore enough inflation to reach a repair shop. For a permanent fix you should have the tire professionally repaired or use a proper plug/patch method.
Will tire sealants harm my TPMS sensors or rims?
Most modern sealants (including the Slime products listed) are formulated to be non-corrosive and TPMS-safe, but always check the product label and follow removal recommendations if you plan a professional repair.
When should I use a plug kit instead of sealant?
Use a plug kit like the Blackjack KT-340 when you want a longer-lasting mechanical repair for a tread puncture. Sealants are better for prevention and quick fixes, while plugs provide a more permanent solution when installed correctly.
