## Can you run different aspect ratio tires?

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. So, if you widen the tire, you may need to decrease the aspect ratio, and vice versa.

## Is a higher tire aspect ratio better?

An important sizing calculation in tire fitting, aspect ratio should be considered with wheel diameter for the best tire and wheel combinations. **Lower aspect ratio typically indicates a high performance tire, with better lateral stability**.

## What is the difference between a 65 and 70 tire?

The series number in a tire-numbering system refers to the aspect ratio of the tire’s sidewall height to its width. **A series 65 tire’s height is 65 percent of its width, a series 70 tire’s height is 70 percent of its width** and so on. These differences in height affect both performance and safety issues while driving.

## How do I choose aspect ratio on tires?

Tire makers calculate the aspect ratio by **dividing a tire’s height off the rim by its width**. If a tire has an aspect ratio of 70, it means the tire’s height is 70% of its width.

## Can I use 235 tires instead of 245?
