FAQs

How do you read Toyota tire sizes?

Toyota tire sizes are typically indicated in a series of numbers and letters on the sidewall of the tire. The format is usually something like this: 235/60R17. Here's what each part means:

  • 235: This is the tire width in millimeters. It represents the measurement from one sidewall to the other when the tire is properly inflated but not loaded.
  • 60: This is the aspect ratio, which is the height of the tire's sidewall as a percentage of its width. In this case, the sidewall height is 60% of the tire's width.
  • R: This letter stands for "Radial," indicating that the tire has radial construction.
  • 17: This is the diameter of the wheel rim in inches that the tire is designed to fit.

Is 265 the same as 31?

No, a tire size of 265 is not the same as 31. The number 265 represents the tire's width in millimeters, whereas 31 typically refers to the overall diameter of the tire in inches. These two measurements are different and cannot be directly compared.

How much difference in tire size is acceptable?

There is some tolerance for variations in tire size, but it's generally recommended to stay within 3% of the original tire diameter. Going beyond this range can affect your vehicle's performance and may lead to issues like incorrect speedometer readings. So, for most vehicles, a 3% difference in tire size is an acceptable limit.

How much bigger is a 35 than a 275?

A 35-inch tire is significantly larger than a 275mm wide tire. The 35-inch measurement refers to the overall diameter of the tire, while 275 represents the width of the tire in millimeters. To convert 35 inches to millimeters, you would get approximately 889mm. So, a 35-inch tire is much taller than a 275mm wide tire.

What does 235 65 R17 mean?

  • 235: The tire width in millimeters.
