Recent tests have revealed that several tire sealants fail to perform as advertised, potentially leaving drivers stranded when they experience a flat tire. This information is crucial for anyone who relies on these products for roadside emergencies, as not all sealants provide the necessary support during critical moments. The findings could impact consumer choices, leading to a reevaluation of which products are truly effective in tire repair.
The Importance of Tire Sealants
Tire sealants are designed to repair punctures and leaks, offering a temporary solution until a more permanent fix can be applied. They are especially popular among commuters, long-distance travelers, and those in regions where roadside assistance is hard to come by. However, the effectiveness of these products can vary significantly, and not all sealants live up to their claims.
Testing Methodology
A recent independent study conducted by the Consumer Product Testing Group assessed various tire sealants available on the market. The tests involved creating punctures in tires and then applying the sealants according to the manufacturer’s instructions. After applying the sealants, the tires were inflated and monitored for leaks over a specified period. The results were startling, revealing that many well-known brands failed to seal the punctures effectively.
Top 10 Ineffective Tire Sealants
Here are ten tire sealants that did not perform adequately during testing, leaving users vulnerable to flat tires:
1. Slime Tire Sealant
Marketed as a reliable option for quick fixes, Slime Tire Sealant consistently underperformed in tests, failing to seal punctures in tires sized 215/60R16 and larger. Users reported leaks within hours of application, making it an unreliable choice for emergency situations.
2. Fix-a-Flat
Fix-a-Flat is widely recognized, but testing showed that it was ineffective in sealing larger punctures, particularly in tires used on 2021–2022 Honda Civics. Many users experienced immediate air loss, leading to the need for a complete tire replacement shortly after use.
3. Stop & Go Tire Sealant
Stop & Go claims to be a quick solution for tire emergencies, yet it failed to hold up when tested on punctures made in 2020 Ford F-150 tires. The sealant lost pressure within hours, causing frustration for those who relied on it for roadside repairs.
4. Berryman B-12 Chemtool Tire Sealant
Although marketed as a professional-grade tire sealant, Berryman B-12 Chemtool did not seal punctures effectively in controlled tests, particularly in tires sized 225/65R17. Users reported that the sealant dried too quickly, failing to form a lasting bond.

TIREJACK’s claims of a permanent seal were discredited in testing, where it failed to seal a puncture in a 2019 Toyota Camry tire. The product left users disappointed as they had to seek immediate professional assistance.
6. MotoSeal Tire Sealant
MotoSeal, designed for motorcycles, was found inadequate in sealing standard car tires, particularly in tests conducted with 2022 Harley Davidson models. Users noted that the sealant did not hold, resulting in continued air loss.
7. Goodyear Tire Sealant
Despite the reputable brand name, Goodyear Tire Sealant did not perform well when tested, particularly on punctures in 2021 Jeep Wranglers. Users expressed frustration when the sealant failed to stop air leaks, leading to unexpected breakdowns.
8. AirMan Tire Sealant
AirMan’s tire sealant was assessed and shown to be ineffective for larger punctures in tires from 2018 Chevrolet Equinox models. The sealant lost effectiveness quickly, leaving drivers stranded without a viable solution.
9. Pro Seal Tire Sealant
Pro Seal, although marketed for heavy-duty use, failed to hold air in test tires, specifically in 2020 Ram 1500s. Users reported that the sealant failed to create a lasting seal, forcing them to seek immediate roadside assistance.
10. NoFlat Tire Sealant
NoFlat Tire Sealant is often touted as a long-lasting solution, but testing showed it was ineffective in sealing punctures in 2022 Nissan Altima tires. Many users faced immediate air loss
