Various tire noise is produced by your car tires while running on a ground surface, however the most common of them all is the tire pattern noise. It is what we are usually referring to when we speak of tire noise. Below are the lists of some of the conditions that can cause your tire to produce a high level pattern noise.

1) If you are using special type of car tires, tire noise level of a rib tire is much lower than the noise level of a lug tire or the block tire.

2) Cars with light load have a lower tire noise level than that of car with a heavy load.

3) Car tires with high inflation pressure produce lower noise level compared to a tire with low inflation pressure which causes a high level of noise.

4) Radial tire noise level is much lower than that of a bias tire noise.

5) Car tires that operate at lower speed produce a lower tire noise level than a tire that operates at higher operating speed.

A tire that has a single pitch pattern tends to generate significant tire noise levels, however to prevent this, tires use a multiple pitch pattern. Even though numerous patterns also generate different pattern noises, but lower intensity than the single pitch pattern tire, the overall tire noise level is much lower.

Tires noise are classified and described as follows

1) Pattern Noise, pattern noise occurs during vehicle operation when air is trapped in the tread pattern and then suddenly released as the tire rolls along the road surface.

2) Squealing, squalling occurs during rapid acceleration, hard braking, and cornering at relatively high speeds. Portions of the tire tread in contact with the road surface begin a self-induced vibration that produces high pitched squealing sounds for several seconds.

3) Road Noise, Noises generated when a vehicle passes over a dimpled road surface or a specifically constructed road surface. Air beneath the tires is forced into the dimples and then escapes to produce the noise. Road noise is usually similar to pattern noise.

4) Elastic vibration noise, Noise produced when a vehicle using tires with poor uniformity passes over a rough road surface. Excitation from either the road or the tire creates the elastic vibration noise.

5) Slip noise, Noise produced by tread movement and slippage at the inside of the tire and road surface contact area.

When selecting the best tire for your car consider also to choose a tire that produces a low level of tire noise, choosing a tire with multiple pitch pattern is a good start if you want to reduced tire noise.
