Tyres are the primary source of contact between a vehicle and the road. Most people however pay less attention to the fact and drive their vehicles with worn and damaged tyres, compromising the very safety.
This is the reason car tyre replacement is extremely important so read on to know when yours need to be swapped! Besides keeping a check on tyre pressure, there’re two other important aspects to ensure longevity of the tyre lifecycle. These are;
Although this isn’t possible on the vehicles having different tyre sizes on both rear and front, equal or balanced tyre rotation is extremely important. Experts recommend having the tyres rotated every 15,000 kilometres and if this is too much of a hassle, make a request at the dealership to rotate the tyres each time when servicing the vehicle.
Much like tyre rotation, wheel alignment should be checked after every 15,000 kilometres. It’s among the most sensitive mechanism that can be upset if the vehicle hits a curb or a pothole. If this has recently happened, wheel alignment is highly recommended for you may be in need ofcar tyre replacement.
Several parameters are there that describes wheel alignment on a vehicle. Some are adjustable whereas others aren’t, some would affect tyre life while other won’t. All these parameters are found within a vehicle as a means to reduce stress and strain on the suspension mechanism and its components.
Causes of various tyre wear
The inward and outward pointing of the wheels concerning the central line of the vehicle is known as the toe. It’s set in a way to take almost any slack in the suspension joints allowing tyres to run parallel to each other when vehicle’s moving in a straight direction. All modern vehicles have tout tolerances which means modifications to the settings are far less. Too much of the toe dramatically reduces the tyre life.
The tilt away from wheel’s vertical is known as the camber. It’s designed to place the wheel loading on the larger wheel bearing on the inner side of the front and rear wheel drive vehicles. Too much camber or arc would only cause the tyre to wear off from the shoulder which would pull the vehicle to one side as you drive.
The retrograde tilt of the steering axis which is designed to give the feel on the steering alongside self-centring is referred to as caster. It allows the steering to straighten up following a turn or corner. Too little caster would cause the vehicle to ramble whereas too much of it would result in strained steering; ending up with car tyre replacement in worse case!
The angle when one of the wheel is a “set back” from the other. In case of higher steering set back, the vehicle is likely to pull towards the side where wheel actually set back. This situation usually arises when a vehicle has already experienced an accident.
The above reasons shed light on a few common factors of tyre wear and damage.
