The wider the tire, the greater the stability

The numbers 175, 185 and 195 are quite common to see on the sides of tires. But do you know what they mean and what their main indications are?

.

These numbers are related to tire specifications. Given in millimeters, they are the width measurements. It's important to note that as the structure of the tire changes, so do certain driving characteristics.

The trend is that the wider the tire, the harder it will be. The wider the tire, the greater its stability. The choice of tire by automakers is based on the relationship between comfort and stability.

.

The ideal tire size is directly related to the technical characteristics of the car. A heavier car requires wider tires. The increase in power and torque also justifies greater width, so that the force is transmitted to the ground without loss of traction.

In this respect, rear-wheel drive or all-wheel drive cars can use narrower sizes than front-wheel drive cars with the same power. Remember that an oversized tire always brings the consumer more disadvantages than benefits. Even if it looks good.

So if you're changing tires, pay close attention to these sizes. Some automakers recommend more than one size for the same car, but this needs to be checked in the owner's manual or by a specialist.
