Is 70 or 75 a wider tire?

70 (or 75) is the ratio of the width to the sidewall height. So a 75 will be a taller tire, and closer to the height of the 6.70x15.

What does 75 mean on tires?

75—This is the tire's aspect ratio, comparing the tire's height to its width. For this tire, it means its height is 75 percent of its width. R—This defines the construction within the tire. “R” stands for radial. “B” means belted bias and “D” stands for diagonal bias construction.

How wide is a 75 series tire?

METRIC TIRE TO DIAMETER (INCHES) CALCULATOR

For example a LT265/75R16 would be around 31.6 inches tall and 10 inches wide.

What number makes a tire wider?

The two-digit number after the slash mark in a tire size is the aspect ratio. For example, in a size P215/65 R15 tire, the 65 means that the height is equal to 65% of the tire's width. The bigger the aspect ratio, the bigger the tire's sidewall will be.

What is 70 on a tire?

If a tire has an aspect ratio of 70, it means the tire's height is 70% of its width. Lower aspect ratio tires, such as a 60 series, generally offer vehicle handling performance advantages over higher aspect ratio tires, such as a 75 series, but a typical trade off can be ride harshness.

Tire Sizes Explained!

Is a 50 or 60 tire wider?

For example, a 60-series tire features a sidewall that is 60% as tall as the tire's section width. A 50-series tire will feature a shorter sidewall, at 50% of section width.

How tall is a 70 series tire?

The number 70 is the aspect ratio, sometimes called the profile. This is the ratio of the sidewall height to the width. The sidewall height can be calculated by multiplying the ratio (70 or 0.70) by the width (225): 225 millimeters x 0.70 = 157.5 millimeters.

What does 50r mean on tires?

50 is the two-figure aspect ratio. This percentage compares the tire's section height with the tire's section width. For example, this aspect ratio of 50 means that the tire's section height is 50% of the tire's section width. R indicates the construction used within the tires casing. R stands for radial construction.

What do the 3 numbers mean on tire size?

B: TIRE WIDTH The three-digit number following the letter is the tire's width (from side to side, looking at the tire head on) in millimeters. This may also be referred to as the section width. C: ASPECT RATIO The forward slash separates the tire width number from the two-digit aspect ratio.

This is how wide the tire needs to be to fit your vehicles rim. - The second number, 75, is the height of the sidewall from the rim of the wheel to the road, also called the Ratio. This is also measured in millimeters. - The 'R' means that the tire is a Radial.

Does width of tire matter?

The tire width will affect their price and several other characteristics, such as grip, noise level, driving comfort, and appearance. Replacing narrow tires with wider ones will usually increase rolling resistance and, therefore, slightly increase fuel consumption.

How much difference in tire size is acceptable?

When changing tire sizes, we recommend staying within 3% of the diameter/height of the original tire. Any more than this and you face the risk of brake failure.

How wide is a 60 R tire?

A P225/60R16 tire is a radial tire that fits a 16-inch rim. It has a width of 225 mm, which equates to being slightly under 9 inches. The sidewall of this tire is 60% of 225 mm, which is 135 mm (approx. 5.3 inches).

What is the difference between 225 50R17 and 225 55R17?

Usually the lower the two-digit number, the wider the tire. The three digits (225) following the service type, tell us the cross-section width of the tire in millimerters. In the example, the 50 width tire will bethe wider tire, whiler 55 will be slightly taller.

What does 55 mean on a tire?

The “55” grouping is the aspect ratio and is by far one of the most misunderstood dimensions. This is the height of the sidewall from wheel to tread relative to the width. Manufacturer's represent this measurement in a percentage, so in our example, the sidewall is 129.25 millimeters — 5.08 inches — tall (235 x 0.55).

R stands for radial construction.

What does 265 60 mean on a tire?

265 = Section Width in millimeters (measured at the widest part of the tire from sidewall to sidewall) /60 = Aspect Ratio or section height to width ratio as a percentage. For this example, the side wall is 60% of the section width of the tire (265mm x . 60 = 159mm). Therefore, the sidewall height is 159mm.

What is the difference between 50 and 55 on tires?

The 50 (or 55) is the height of the sidewall, as a percentage of the width. That's your aspect ratio. With a 55 aspect ratio, and a 225 treadwidth, you'll end up with a tire that is 3/4 of an inch taller that the 225/50.
