Propylene Glycol Based
Permaseal is such a sealant. The propylene glycol base makes it a very consistent sealant which will not freeze, separate or dry out under adverse conditions. In addition, because the propylene glycol base is mixed with other ingredients to produce the exclusive formula, it makes Permaseal the most advanced tire sealant on the market.

The Challenge
Tire sealants have been around for a long time, but for many years the industry could not produce a sealant which could withstand the pressure and stresses in tires at speeds over 30MPH for any appreciable length of time.

The Solution
However, in 2003, by applying new technology, the breakthrough came about. A tire sealant, which could tolerate heat, cold and the centrifugal forces imposed upon it, was created. Permaseal is that product.

Permaseal has a revolutionary water and chemical formula that enables the product to remain fluid at all times, thus enabling the product to immediately seal a puncture wound made by a puncture object of up to 12 mm in a commercial vehicle tire in the main tread area of the tire, without loss of pressure.

As a result, Permaseal gives the advantage of longer tire life together with lower downtime and maintenance costs.

Permaseal is classified as non-toxic, non-hazardous. It does not require (EPA) Environmental Protection Agency classification and compiles with all (TSCA) Toxic Substance Control Authority requirements.

Look for these wear patterns to help you identify tire problems early, before they become costly or dangerous. If you spot any of these conditions it is usually best to get it looked at immediately.

Re-Capping
The heat generated from an under inflated tire often contributes to re-mould separations. Tubeless tires are particularly susceptible to tread separation. Frequently, small holes in the inner liner are overlooked in the pre-retread inspection. High pressure air passes through the hole to the new rubber of the tread. With the escape route cut off, its spreads out between the old casing and new tread until separation and failure occurs. In sealing these small inner holes, Permaseal reduces the pressure on the new tread, so the full service life is achieved without incident.

Re-Capping vs New tires
With the use of various modern compounds and better tread quality, the industry has come a long way. Most fleet managers consider recapping a necessity as a means of cutting cost. Some recapping tires will out live comparable new tires. So, a re-cappers skill is much relied upon.

How many caps should each casing provide?
This is a popular question that is difficult to answer due to its broad spectrum of variables. With preventative tire maintenance a fleet owner would expect to get one or two caps from a casing. A stringent preventative maintenance program adds up to a considerable cost in labor and tire repairs. However with Permaseal, once the tires have been treated, porosity leaks, bead leaks and punctures have been eliminated, thus cutting, labor costs, tire repairs and down time. This added to the tire being constantly maintained at the correct pressure, will ensure no weakening of the tire wall due to under inflation and could add, up to another two cappings per tire. (No tire maintenance program can eliminate tire side wall weakening due to impact)

Note - Permaseal is water soluble and should be washed out of the tire before re-capping. Once this is done there is nothing to prevent the normal re-capping process.

Fundamental to the proper use and maintenance of tires is ensuring the tires are kept at the correct pressure.

Correct Inflation
A tire is an envelope consisting of materials forming a long chain of macromolecules. The tire itself does not carry the load, rather it is the air within the tire that carries the load and provides the only support between the vehicle and the road. The working of a tires are dependent on correct air pressure and manufacturers agree that under or over inflation will restrict tire life considerably.
According to Goodyear. “Correct inflation is the most important fact in tire life. Neglect of tire maintenance, and especially tire pressure maintenance, has cost fleets thousands of pounds. Under inflation should never be permitted”.

Under Inflation
tire manufacturers aware that porosity in their tires is one of the main causes of under inflation, have passed on the responsibility of maintaining correct tire pressure to the user. But it is difficult to program the human factor of the vehicle (the driver), on the necessity of checking and replenishing the air in the tires on a routine basis.

With out a way to eliminate porosity, it is essential to establish a routine tire care and maintenance program. Additionally that program must be followed stringently in order to obtain good results.
Under inflation is the most detrimental condition a tire can endure and will rapidly induce premature tire failure. A vehicle can obtain up to an additionally 20% tire life and can cut fuel cost by 5% by simply maintaining the correct pressure. The result of under inflation are:

• Increased rolling resistance, resulting in higher fuel consumption
• Poor pavement grip, decreasing safety
• Blow out risk, due to over heating
• Reduction in resistance of punctures and cuts
• Destruction of casing carcass, making re-treading impossible
• Ply separation
• Uneven tread wear

How does tire inflation affect maintenance costs?
If a tire is correctly inflated it will have less rolling resistance, which will result in maintaining a cooler operating temperature, longer tire life and better fuel mileage.
A god example is the wheelbarrow. If you have a barrow loaded with sand and it has an under inflated tire, you will find it very difficult to push around. Inflation the tire to the correct pressure and you can push it anywhere. The same applies to a vehicle; the only difference being the engine is using more costly fuel than necessary.

Air loss

By their very nature all rubber tires are porous and lose air albeit slowly and unless the tires are checked regularly tires will invariably be running at below their optimum pressure. Porosity is one of the main causes of under inflation. Tread separation and heat build up caused by under inflation can occur and will in turn precipitate tire failure and blowouts.

To eliminate porosity, the use of Permaseal is strongly advised.
