What does 245/70r17 Tire mean?

This question reminds me of when I was in school, learning about algebra. Suddenly, numbers and letters were mixed together and, just like that, math became a foreign language. The good news is, I have since learned to speak “tire” fluently and I promise it’s much easier than high school algebra!

Let’s break it down with a table for easy understanding:

Tire NumberExplanation
245This is the tire width, or the measurement of the tire from one sidewall to the other sidewall, in millimeters.
70The aspect ratio, which represents the height of the tire’s cross-section as a percentage of the tire’s width. So, the height is 70% of 245mm.
RThis stands for Radial, indicating the construction of the tire. Radial tires have layers of fabric with cords running at right angles to the circumference of the tire.
17The diameter of the wheel rim in inches that the tire is designed to fit.

Now you know! Every time you look at your tires, you’ll see these numbers and letters and understand exactly what they mean. A moment of silence for the mystique that was once attached to tire codes, please.

What is 245/70r17 Tire in inches?

So, now that we have our tire deciphering degree, let’s dive deeper into the inches game. Understanding tire dimensions in inches is particularly useful, especially for those of us more familiar with the imperial system of measurements.

Measurements of 245/70R17 in inches and Millimeters

Let’s convert these measurements using a table for easy comprehension:

Rim Diameter17 inches431.8 millimeters
Sidewall Height6.75 inches171.45 millimeters
Circumference95.76 inches2432.96 millimeters

So, there you have it! The 245/70R17 tire size in all its imperial and metric glory. I’m sure this will make you the life of the party at your next get-together (or at least it might earn you a free drink if you win the bar trivia!).

Tire width of 245/70r17

The width of a 245/70R17 tire is, wait for it… 245 millimeters! Now, if you’re more comfortable with inches (or you just want to impress your friends with your quick math skills), that’s approximately 9.65 inches. 

It’s roughly the width of three golf balls lined up in a row. This width determines how much of your tire can smile at the road at any given time, which in turn affects your vehicle’s handling and grip. Just remember, wider isn’t always better – like trying to fit an elephant into a smart car, there are limitations!

Tire height of 245/70r17

The height of our tire isn’t explicitly stated in the 245/70R17 designation. It’s actually the tricky 70 figure, which is not the height in millimeters but a percentage – the aspect ratio! This number signifies that the height of the tire’s cross-section (sidewall) is 70% of the tire’s width. So, whip out your calculators (or dust off the math part of your brain) and let’s do the math: 70% of 245mm gives us approximately 171.5mm. That’s about 6.75 inches. Remember when your math teacher said you’d use this in real life? They were right!

Sidewall height of 245/70r17

Now that we’ve deciphered our tire algebra, the sidewall height comes out to be the same as our tire height – 6.75 inches, or 171.5 millimeters. 

That’s the approximate height of 2.7 classic Coca Cola cans stacked on top of each other. This dimension influences the ride quality and handling of your vehicle. Thicker sidewalls absorb more road bumps – kind of like how your favorite pillow absorbs all your end-of-the-day worries.

Rim diameter for 245/70r17

The rim diameter is thankfully the simplest of the lot. It’s the number after the “R”. So for a 245/70R17, the rim diameter is… drumroll please… 17 inches! That’s the size of a large pizza, or an average unicycle wheel. And much like how the perfect pizza size can lead to dinner happiness, the perfect rim diameter can lead to a smooth and balanced ride.

Tire circumference of 245/70r17

The circumference of a 245/70R17 tire is approximately 95.76 inches or 2432.96 millimeters. That’s almost the height of NBA superstar Shaquille O’Neal! This gives you about 662 tire revolutions per mile. It’s an often overlooked fact, but the tire circumference affects your speedometer’s accuracy.

 So next time you’re considering replacing your tires, remember the circumference – or you might end up explaining to a police officer why you were speeding, and I guarantee they won’t accept “my tires tricked me” as a valid excuse.

Comparison with similar tires

In the tire world, comparisons are just as important as they are on a reality TV cooking show. Let’s spice things up a bit with some head-to-head battles in the tire arena!

245/70r17 vs 265/70r17 

The primary difference here lies in the width of the tire. The 265/70r17 is 20mm wider than the 245/70r17, potentially providing better stability and traction, but it may negatively affect fuel economy.

245/70r17 vs 265/65r17 

While the 265/65r17 is wider, it has a smaller aspect ratio (the ’65’ part), resulting in a lower sidewall height. This means potentially better handling but a less comfortable ride compared to the 245/70r17.

245/70r17 vs 285/70r17 

Here, the 285/70r17 is significantly wider and slightly taller than the 245/70r17. This could result in better traction and ground clearance, but it could negatively impact fuel economy and ride comfort.

245/70r17 vs 255/70r17 

A relatively minor difference here: the 255/70r17 is 10mm wider but maintains the same aspect ratio, resulting in slightly improved stability without a significant impact on ride comfort.

245/70r17 vs 245/65r17 

These tires have the same width, but the 245/65r17 has a lower aspect ratio, resulting in a smaller sidewall. This could lead to slightly improved handling but at the cost of ride comfort.

245/70r17 vs 245/75r17 

In this case, both tires have the same width, but the 245/75r17 has a taller sidewall, providing a more comfortable ride and potentially better off-road capabilities due to increased ground clearance.

245/70r17 vs 235/80r17 

The 235/80r17 is narrower and taller than the 245/70r17. This results in increased fuel economy and ground clearance, but at the expense of handling and stability.

245/70r17 vs 255/65r17 

The 255/65r17 is wider but has a shorter sidewall than the 245/70r17. You’ll potentially get better handling, but you might sacrifice some ride comfort.

245/70r17 vs 235/65r17 

Here, the 235/65r17 is narrower and has a shorter sidewall compared to the 245/70r17. This results in potentially better fuel efficiency but a less comfortable ride.

245/70r17 vs 255/75r17 

The 255/75r17 is wider and has a taller sidewall than the 245/70r17. This could result in better off-road performance and ride comfort but at the expense of fuel economy.
