## What is the size difference between a 215 tire and a 225 tire?

215 and 225 are the tire widths measured in millimeters. That said, 225 is wider than 215, however, in terms of aspect ratio, the latter has a higher profile. These two tire sizes also serve a specific purpose depending on general usage.

## Which is a taller tire 235 or 225?

215 and 225 are the tire widths measured in millimeters. That said, 225 is wider than 215, however, in terms of aspect ratio, the latter has a higher profile. These two tire sizes also serve a specific purpose depending on general usage.

## What does the 235 mean on tires?

So “235” means that the tire has a nominal width of 235 millimeters. The following “55” is the tire wall height as a percentage of the width. So in our example, the actual height in millimeters would be just under 130 mm. Then comes the letter “R” as the identifier for radial tires.

## Is 235 the height or width of a tire?

The “235” grouping indicates the width of the tire from sidewall to sidewall in millimeters. So, in this example, the tire is 235 millimeters — 9.25 inches — wide from sidewall to sidewall.

## What is the difference between 215 and 235 tires?

The reason why is simple – the narrower the contact patch – the greater the pressure. This means that a 215 tire is going to dig into the snow better than a 235 tire. The differences between 215 and 235 tires are even greater when it comes to aquaplaning or standing water.

## What number makes a tire taller?

After the slash is a two-digit number, which dictates the Aspect Ratio. This ratio measures the height of the tire’s cross-section to its width. In our example, the Aspect Ratio is ’55’, meaning the height of the tire is equal to 55 percent of the tire’s width. The larger the aspect ratio, the taller the tire.

## How much difference in tire size is acceptable?

## Are wider tires better?
