Millard Tyre Centre supplies tyres from passenger to earthmoving tyres from many manufacturers including Simex, Continental and Uniroyal.
Continental produce 100,000,000 tyres per year globally and growing. Continental works closely with leading car manufacturers on the development of tyres to continually improve safety, comfort, fuel economy, mileage and low noise levels.
Uniroyal have put together the following guide - Symmetrical Tread Pattern Design 
Symmetrical tyre designs are the 'all rounder' tread pattern design. They are generally the most comfortable and produce the least noise of the three tread pattern
designs, however they are not as performance orientated as the other designs.
Tyres with a symmetrical tread design can be cross rotated to maximise tyre life and are designed to wear evenly for greater balance, steering response and comfort. Asymmetrical Tread Pattern Design 
Asymmetrical tyre designs are oriented towards sports and performance applications and feature multiple tread patterns across the tread design - each performing a
different application. The solid circumferential band provides excellent straight line stability, whilst the transverse grooves provide cornering grip and the channels for
effective water displacement.
In most instances, this combination of designs provides adequate wet weather performance, improved braking and driving comfort. Assymetrical tyres are able to be cross rotated to maximise tyre life. Directional Tread Pattern Design 
This pattern design ensures fast water ejection and good contact between tyre and road. Consequently, Directional designs provide excellent performance in both wet
and dry driving conditions.
However, due to the larger contact area between the tyre and the road, they tend to have slightly higher rotational noise levels than Symmetrically designed tyres. Futhermore, Directional tyres are unable to be cross rotated in their application to extend tyre life.

Give those tyres a 'check up'!
Checking your tyres is one of the most important safety factors of driving. Moderate driving needs a monthly tyre check, while more frequent usage should be checked weekly or fortnightly to determine if your tyres have become worn and need replacement. Tyres have a 'wear marker' set at a depth of 1.5mm, the legal minimum depth of a tyre's tread. Tread depth above that mark are legal and safe, but if below 2mm the tyres may perform poorly in wet conditions. In addition to checking the depth of your tyre's tread, you should look for cracks, holes or splits in each tyre. If any of these are noted, the tyre should be inspected by an authorised dealer right away and replacement should be considered. While checking the tyres you are driving on, don't forget to check your spare. Your tyre pressure may have decreased and need to be refilled. |
