# 255/70r17 In Inches – Tire Size, Rim Fitment & Best Tires

The 255/70R17 tire has an overall diameter of approximately 31.1 inches, a section width of roughly 10 inches, and is designed to be mounted on a 17-inch diameter rim. The equivalent tire size in the high flotation system is 31.1x10R17.

## What does 255/70r17 Tire mean?

Ah, the mystery of tire markings. At first glance, it might seem as cryptic as grandma’s secret meatloaf recipe, but we’re going to demystify it together. Let’s decode this “255/70r17” in a neat table. Buckle up!

## What is 255/70r17 Tire in inches?

You might wonder why we’re using both inches and millimeters here. Well, it’s because tire measurements are a mixed bag of metric and imperial systems, just like a good bowl of trail mix. We can convert the section width and sidewall height into inches for our American friends.

## Tire Size Conversion: 255/70r17 in Inches and Millimeters

This tire size can be a bit difficult to visualize. To help, here’s a table that breaks down the measurements of a 255/70R17 tire in both inches and millimeters.

The tire diameter is calculated using the section width, aspect ratio, and wheel diameter. Sidewall height is derived from the aspect ratio percentage of the section width. The tire circumference is calculated using the diameter, and revolutions per mile are calculated from the circumference. The math can be a little intimidating, but don’t worry – you won’t be quizzed on it later!

Just as a fun fact, remember that each tire revolution on a 255/70R17 covers about 97.6 inches – that’s roughly the height of an adult male giraffe’s heart! And you thought tire size wasn’t interesting.

Now you can confidently decipher tire dimensions as easily as your morning crossword. It’s an underappreciated art form, but we’re glad to be on this enlightening journey with you. So next time, when someone is lost in the labyrinth of tire sizes, you can guide them out, all thanks to your newfound understanding of a tire’s ‘mysterious’ numbers and letters!

## Tire Width of 255/70r17

The tire width, or section width as it’s sometimes called, is that “255” nestled at the start of our “255/70r17” tire size. It indicates the width of the tire in millimeters from sidewall to sidewall. Picture two slices of bread as the sidewalls and the delicious filling in the middle as the tread.

In this case, that filling is a mouthwatering 255 millimeters (or about 10 inches for those who prefer their sandwiches in imperial measurements). As they say, more width, more stability – or is that just something we say in the tire world?

## Tire Height of 255/70r17

Now, tire height, or diameter, is a bit of a tricky one. It’s not directly provided in the size “255/70r17”, so we have to do some math to figure it out. Here’s how: We first determine the sidewall height (70% of 255mm, which is approximately 178.5mm), multiply this by 2 (because tires have two sidewalls, you know), and then add the diameter of the rim (17 inches, which is 432mm).

All this sums up to approximately 790mm, or about 31.1 inches. This tire isn’t quite Shaquille O’Neal tall, but it’s a pretty good size for getting you over those potholes.

## Sidewall Height of 255/70r17

Next up, we have the sidewall height, represented by that “70” in our tire size. This isn’t a direct measurement in millimeters or inches, but a percentage of the tire width. A 70 aspect ratio means the sidewall height is 70% of the tire width.

So, take 70% of 255mm, and we get approximately 178.5mm, or about 7 inches. That’s about 18 stacked Oreos – not that we recommend using cookies as a measurement tool, but it does sound like a tasty experiment!

## Rim Diameter for 255/70r17

The “17” in “255/70r17” tells us the rim diameter in inches. So, we’re dealing with a 17-inch rim here. The tire is designed to snugly fit on a rim of this size, like a well-tailored suit or a perfectly toasted bagel fitting beautifully on your morning plate. For our metric system friends, that’s 432mm.

## Tire Circumference of 255/70r17

Lastly, the tire circumference isn’t explicitly written in the tire size, but we can calculate it using the tire diameter. Multiply the diameter (31.1 inches) by π (3.14), and we get a circumference of about 97.6 inches, or 2480mm.

This is the distance your vehicle will travel with one complete spin of the wheel. If you drove around the earth’s equator, your tire would have to turn over 1,034,363 times! Now that’s a road trip!

## What are the best 255/70r17 tires?

Choosing the best tire is like picking the best dessert – it depends on the occasion, your preferences, and yes, sometimes even the weather.
