How to determine tire size

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 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. In this example, the aspect ratio is 65, meaning the sidewall is 65 percent as high as the tire is wide.

How do you measure tire size in inches?

The first number on a metric tire is the width in millimeters. Divide this number by 25.4 to get the inch equivalent as there is 25.4 mm in 1 inch. The third number generally preceded by an “R” is the wheel diameter. The sidewall or aspect ratio are used in metric tire sizes to determine the overall height of a tire.

Can I use 235 tires instead of 225?

Obviously, you will need a certain kind of tire depending on how you use your vehicle. Due to this, a 235 tire might not be better than a 225 tire, or vice versa, but depending on your situation, one tire might serve you better than the other.

Which is wider a 50 or 60 series tire?

The second number on a tire size refers to the aspect ratio: This is the ratio of its section height to its section width. The smaller the number, the shorter the sidewall and the wider the tire. In other words, a 50 series tire is shorter and wider than a 60, even though they both might be 275’s or whatever.

What is the difference between 265 70 and 265 75?

For the 16″ rims, 265/70 is the stock size. Going from 265/70 to 265/75 is increasing the height, or diameter, of the tire. The tire will be an inch taller. 265 is the width, so stock size is 265 millimeters wide.

Which tire is wider 60 or 75?

Generally speaking, a 215-60 series tire is wider and has a shorter sidewall then a 215-70 series tire would be and a 215-75 series tire would be taller and narrower then either the 70 series or the 60 series. The 215 designation would be the amount of weight the tire can carry at a given tire pressure.

Will a 275 tire fit a 10 inch rim?

Yes, 275 will fit on a 10″ rim. 275mm = 11″, so the section width is wider than the rim. with a tread width of around 9.75″, the tire is only slightly narrower than the rim.

Are 265 75R15 the same as 31×10 5r15?

They’re virtually identical. I think the main reasoning behind the different size ratings is the 265 75R15 is usually more of a street oriented tire whereas the 31×10. 5″ has a more “truck” oriented tread.

What happens if you have different size tires?

This applies to switching to both smaller and larger tires. Changing to larger tires with an improper sidewall height can cause damage to your vehicle’s suspension system, wheels, and the tires themselves, and can run the risk of incorrect speedometer readings.

Can I use 215 65r16 instead of 225 60R16?

They’ll definitely fit alright I even ran 215/60/16s (rather than standard 245/50/16s) on my factory 16×8 Firebird wheels in the winter without a problem.

How wide is a 265 tire?

METRIC TIRE TO DIAMETER (INCHES) CALCULATOR For example a LT265/75R16 would be around 31.6 inches tall and 10 inches wide.

What is the difference between 265 70R17 and 285 70R17?

The larger 285/70R17 tire in the photo above stands over an inch taller and is nearly an inch wider than the 265/70R17 size. The width of the tread is also a half-inch wider. Many late-model domestic trucks accept this difference in size.

Can I use 225 65r17 instead of 235 60R17?

Not safely, no. If you go to a narrower tread width tire you will want to increase the sidewall height aspect ratio exponentially. The shorter sidewall 225/60R17 tire will not provide the needed load carrying capability needed for your vehicle.

How wide is a 50 series tire?
