Replacing a tire can be daunting, especially if you have All Wheel Drive (AWD). You often have to change all the tires at once. It might not make sense to discard three perfectly working tires just because the fourth needs to be replaced. However, once you understand the underlying wheel dynamics, you will see why this is a good idea.
Various manufacturers and car experts have determined that a vehicle should have four matching tires. The type, model and even the degree of wear should be the same. Having all four tires the same ensures cornering, braking and acceleration are balanced and predictable. However, if any of these factors differ between two wheels, that difference will affect traction characteristics and performance.
In today’s article we discuss when you need to change your tires and what to consider if you only need to replace one or two tires instead of all four.
