What is the size of a 285 tire in inches?
3 Answers
285 tire only indicates the tire width of 285mm, not the size in inches. A 285/70/17 tire represents a width of 285mm, an aspect ratio of 70, and a diameter of 17 inches. Below is a detailed introduction to car tire specifications: Overview: Tire types have international standard tire codes, which indicate the section width and aspect ratio percentage in millimeters. This is followed by the tire type code, rim diameter (in inches), load index (permissible load capacity code), and permissible speed code. Others: For example, in 175/70R-14-77H, 175 represents a tire width of 175MM, 70 indicates the tire's aspect ratio is 70%, meaning the section height is 70% of the width, the rim diameter is 14 inches, the load index is 77, and the speed rating is H.
Is 285 tire size in inches? Let me clarify, 285 refers to the tire width of 285 millimeters, not the size in inches. A complete tire specification, such as 285/70R18, indicates that 18 inches is the wheel diameter. So, just looking at 285 won't tell you the inch size. In reality, 285-width tires are typically used for SUVs or pickup trucks, with wheel diameters usually ranging from 17 to 20 inches. Don't guess the size yourself—check the vehicle manual or the sidewall markings for the full specification. Choosing the wrong size can lead to problems like unstable handling or increased fuel consumption. I once drove a friend's car with 285/65R17 tires on 17-inch wheels, and the handling was very stable. I recommend going to a professional shop for tire changes to ensure safety and peace of mind.
Let's talk about the size of 285 tires. 285 refers to the width in millimeters, while inches indicate the wheel diameter, such as 18 inches. In tire specifications like 285/65R20, the 20 represents inches. 285-width tires are commonly paired with wheel sizes ranging from 17 to 22 inches, especially popular on pickup trucks or luxury SUVs. From experience, larger wheels look cooler but the aspect ratio affects comfort; when changing tires, don't alter the size randomly—ensure it matches the original specifications to avoid impacting braking and tire lifespan. Safety first, it's recommended to regularly check tire pressure and wear.
