The amount of sealant for a given tire/application is dependent upon the size of the tire. Check out Stan’s Tire Sealant calculator as a guide for recommended dosages for the most common tire size applications.

To extend the shelf-life of the Stan’s Tire Sealant, bottles should be kept tightly sealed and stored in a cool, dry place. The sealant can be expected to last for many years if not used.

There are many factors that impact the time that Stan’s Tire Sealant will last in most tires. Those factors include: temperatures in your area, weather and humidity conditions, machine use, where the machine is stored (cooler is better), tire casing thickness, number of punctures that Stan’s Tire Sealant sealant has already sealed that you may never knew you had. In average conditions, the Stan’s Tire Sealant will last nearly two years in a tire.

Tires should be ‘topped off’ approximately once a year as part of your regular maintenance program. As a general rule, adding approximately 1/4 of the original dosage is best practice. Keep in mind you may need to adjust this depending on the environmental conditions and whether or not you have lost some sealant through punctures.

Animal and human friendly antifreeze agents allow Stan’s Tire Sealant to be used in environments as cold as -20°F (-28.8°C)

Stan’s Tire Sealant Instantly seals punctures up to 1/2″ in treads and sidewalls.

Any trace amount of ammonia in Stan’s Tire Sealant will evaporate soon after it is injected into the tire. We have found no damaging effects from our sealant even after years of use.

Using Stan’s Tire Sealant may void the tire warranty with certain manufacturers. Stan’s sealant will not damage your tire. Please consult your tire manufacturer’s warranty guidelines.

Liquid sealant can be rinsed out with water or wiped away with a rag. Stan’s Tire Sealant is non-toxic. It is not necessary to remove dried sealant from your tire, but large areas can be peeled away by hand or scrubbed away with a stiff brush.

Rinse any spills with cold water as soon as possible; do not let the sealant dry. We also recommend using a surfactant-based detergent such as Tide. Unfortunately, once your clothing is stained, it will most likely not come out.

If you plan to add sealant when mounting a new tire or, if you will unmount and remount the tire to add sealant, no. If you plan to add sealant through the valve stem, you will need a schrader valve core remover.

This is the natural process of the sealant evaporating. It is more evident in some tires, but is nothing to be overly concerned about. This “weeping” does not impact the effectiveness of the sealant. The weeping will dissipate as the sealant seals the casing of the tire. More porous tires may require a sealant refresh shortly after the initial setup.

We cannot recommend that Stan’s Sealant is mixed with any other sealant.  The primary reason is because all sealants are not created equally in their material makeup and mixing them may cause undesired results.
