Do you have to use the exact tire size?

Generally, the worst issue you will cause by changing the size is an inaccurate speedometer. That said, the only dimensions you can change are the width and aspect ratio — never the wheel size, unless you buy replacement wheels — and you should always strive to keep the total height of the tire the same as the OEM.

How tire size affects performance?

WHEEL SIZE NOT only affects a car's performance but it also has an impact on noise levels, comfort and fuel economy. As tyre sidewall height decreases, performance tends to get sharper and handling usually improves too. ... Also, larger tyres weigh more so this too will also negatively affect fuel consumption.

Do bigger tires give a smoother ride?

What do you need to know about tire diameter?

By doing so, you can determine the axle gearing you’ll need to use with your new tire diameter in order to maintain (or enhance) performance. You’ll need three figures to do this: your vehicle’s current rear axle gearing, the diameter of your existing tires, and the diameter of the tires you want to use.

When do you need new tires for a bigger wheel?

When you move to a larger wheel diameter (such as from 17 to 18 inches), you need new tires to match. Those tires need a lower profile (or sidewall height)  to maintain adequate clearance when they go over bumps and potholes, which makes the suspension fully compress and rebound.
