FAQ

Also, the process is the same whether or not the penetrating object stays in the tire.

How does MULTI SEAL® Tire Sealant with KEVLAR® seal leaks and prevent under-inflation

caused by slow leaks?

Under-inflation in tires occurs:

1. naturally because of the porous nature of tire rubber

2. because of slow leaks around the rim

3. because of slow leaks around the valve stem

MULTI SEAL® Tire Sealant with KEVLAR® coats the inside of the tire, dramatically reducing

porosity. As the sealant spreads around the tire and rim, slow leaks from the bead, pin holes in

the rim and leaking valve stem problems are fixed in a similar fashion to punctures.

Because MULTI SEAL® Tire Sealant with KEVLAR® lasts the life of the tire, the need to

frequently “air up” the tire is significantly reduced.

How effective is MULTI SEAL® Tire Sealant with KEVLAR® at sealing punctures?

MULTI SEAL® Tire Sealant with KEVLAR® seals up to 95% of punctures in the tread area of most

tires (i.e., tubeless tires).

For tires that have inner tubes, including some lawn mower and wheelbarrow tires, MULTI

SEAL® Tire Sealant with KEVLAR® seals up to 70% of tread area punctures.

Why is there a difference in the effectiveness between tubed and tubeless tires?

Effectiveness in tires that have tubes is lower for several reasons:

• In many cases, the tubes are very thin and cheaply made. These tubes rip when they get

punctured, which makes them very difficult to seal.

• We also see a lot of tubes that are not properly sized for the tire: They’re either too big

or too small. This also can lead to ineffective sealing due to movement of the tube inside

the tire or ripping.
