The use of PREVENT-A-FLAT in pneumatic tyres can hydrodynamically balance highway truck tyres. Liquid balancing is a sound, time proven technique.

The ability of PREVENT-A-FLAT to always remain a liquid is a vital attribute to increased tyre tread life. It allows it to shift as the tyre wears or as road or load conditions vary. Whilst most fleet operators balance the tyres on the steering axles, they do not even try to balance either the drive or the trailer tyres. This results in waste of potential service life on the unbalanced tyres. Liquid balancing using PREVENT-A-FLAT provides an effective yet inexpensive solution to the problem.

With conventional tyre balancing methodologies, dual tyres and wide, flotation tyres are almost impossible to balance.

OUT OF BALANCE HIGHWAY TRUCK TYRES RESULT IN:

1. RAPID, UNEVEN TREAD WEAR
2. IMPAIRED DRIVER CONTROL
3. DRIVER FATIGUE
4. EXCESSIVE BEARING WEAR AND CHASSIS DAMAGE
5. POTENTIAL DAMAGE TO FRAGILE CARGOES

Upon initial installation it will take a few kilometres of driving to distribute PREVENT-A-FLAT properly within the tyres. Subsequent runs should balance within a few hundred metres.

High speed deformation of tyres, rapid braking or acceleration, may pose balance problems.

NOTE: In mechanical spin testing the tyre may or may not show as balanced. However, on road testing vibration analysis should indicate a consistently balanced condition.

Balancing Service Hints

1. It is important to recognise that not all vibration problems are tyre balance related. However, in those instances where the vibration is a result of an out of balance tyre situation, PREVENT-A-FLAT is normally the solution.
2. Prior to balancing, remove any previously installed rim lead weights.
3. Excessive tyre talc, foreign objects in the tyre and/or water in the tyre can have an adverse effect on balancing.
4. If the quantity of PREVENT-A-FLATshown on the installation chart does not stop the vibration, add up to 250ml more.

Should the vibrations continue check for the following:

1. Out of round tyres or rims.
2. Excessive lateral run-out
3. Shifted belting in tyre
4. Tread separation
5. Creased tube in tyre
6. Toe-in (O0 for radial tyres)
7. Mechanical malfunction
