As tyres are used, it is normal for the tread to gradually become shallower and overall tyre performance to change. In addition, irregular tread wear may occur for a variety of reasons that may lead you to have to replace a tyre sooner rather than later. Regularly checking the tread depth and wear condition of each tyre on your vehicle will not only let you know when it is time to replace a tyre, it can also help you detect other needed maintenance and get the most value out of your vehicle and tyres.

WHY TYRE WEAR MATTERS
Too little tyre tread can create unsafe driving conditions. When tyres can’t grip the road, a driver may lose control of their vehicle. When roads are wet , tyre tread depth is especially important. Anytime precipitation gets between your tyres and the road, you need the tread to cut through it and maintain as much contact with the road surface as possible. The more shallow your tread, the more easily you may lose traction when driving in the wet; reducing speed in wet conditions helps you maintain grip.

WHAT CAUSES EARLY WEAR OUT OR IRREGULAR TYRE WEAR?
Just as vehicles, drivers, and driving habits are different from each other, not all tyres are the same and they can wear at very different rates. For instance, high performance tyres for sports cars may wear more quickly than touring tyres for a family sedan. However, a variety of factors can cause a tyre to wear out sooner than expected, and/or cause it to wear irregularly and create noise or vibration. Two common causes of early tyre wear and irregular tyre wear are improper inflation pressure and out-of-spec’ alignment conditions.

TYRE TREAD WEAR CAUSE 1: IMPROPER INFLATION PRESSURE
When a tyre is improperly inflated, there’s a good chance it will start to wear more rapidly and/or unevenly. Not only do vehicle manufacturers specify the inflation pressures for the front and rear tyres to optimize performance for ride comfort, handling and fuel economy, they also take into consideration natural tyre wear. Proper inflation pressure (which should be checked on a cold tyre) helps optimize distribution of vehicle load, acceleration, braking, and cornering forces in the tread. If the tyre pressure is too low, or even too high, the contact patch of the tyre tread is not optimized to handle the wide variety of jobs it is asked to do. Thus, different parts of the tread may be abraded away more quickly and/or irregularly.



Check the pressure in all of your tyres, including the spare, every week . Also check it before going on a long trip or when you plan to carry extra load. You can find the vehicle manufacturer’s tyre pressure specifications on a placard/label affixed to the engine bay, driver’s door or along the door jam b. You can also check your vehicle owner’s manual for tyre pressure recommendations.

TYRE TREAD WEAR CAUSE 2: OUT-OF-SPEC’ TYRE ALIGNMENT
Tyre alignment, also known as wheel alignment, refers to the adjustment of the vehicle’s steering and suspension components – the system that connects and controls the motion of the wheels. It is not an adjustment of the tyres or wheels themselves. The key to proper alignment is to adjust the angles of the tyres and their contact with the road in accordance with the vehicle manufacturer’s specifications for parameters such as camber, toe, and caster.

Improper tyre alignment can cause your tyres to wear unevenly and prematurely. Common irregular tyre tread wear conditions from improper alignment include the following:

Heel/toe tyre wear: This happens when one side of the tread blocks is wearing faster than the other side circumferentially. When you run your hand over the tread blocks, they will feel like saw teeth. Heel/toe wear typically occurs in a shoulder rib and is often caused by excessive positive or negative toe.



Feather edge tyre wear: Tyres are “feathered” when the tread ribs are worn lower/smoother on one side and higher/sharper on the other. This is often caused by a combination of improper alignment settings, such as excessive toe and caster.



One-sided shoulder tyre wear: This type of irregular tread wear means the inside or outside shoulder rib of the tread is significantly more worn than the other ribs. Also known as camber wear, excessive positive or negative camber often causes this type of wear.



It is imperative to keep your tyres properly maintained by checking your tyre pressures weekly. If you’re experiencing any unusual wear patterns, you should have a qualified technician check your alignment.
