That depends on what the aspect ratio is. The 285 is just the width of the tire in millimeters. A 285/60 series is not the same size tire as a 285/50 series.
Which Tire is bigger you ask? The 30X9.50r15 is larger than the 16 in tire in width. To get the width of the 15 inch tire you need to multiply 30 by 9.50. This will give you a total width of 285. So the width of the 15 inch tire is 285mm wide. The width of the 16 inch tire is 225. So there is a difference of 60 mm. I am not familiar with the Jeep Cherokee. I have seen a few people place 255/70r/16s on their jeep cherokees. I think 285 mm wide tires might be a little too wide. If you decide to lift this jeep, then you should not have a problem placing a 285 mm wide tire on it.

The difference between a 285/65R18 and a 275/65R18 is height and width The first 3 digit number is the width measured in millimeters, 285 millimeters and 275 millimeters wide across the tread. The middle two digit number is an aspect ratio number or a percentage of the width. For example if the tread is 285 millimeters wide, than the aspect ratio of 65 is 185.25 millimeters. Meaning the side wall of the tire is 185.25 millimeters tall. 65 percent of 285 millimeters is 185.25 millimeters. So a 275 millimeter tire with the same aspect ratio of 65 will be a narrower and shorter tire, because 65 percent of 275 is less than 65 percent of 285. The R18 means that the tire is of radial construction and the tire is made to be mounted on a 18 inch wheel or rim.
The 33 is measured in inches, the 285 is measured in millimeter's.
A 285/70R17 tire has a height of approximately 31.8 inches (about 807 mm). The first number (285) indicates the tire's width in millimeters, the second number (70) is the aspect ratio (the height of the sidewall as a percentage of the width), and the "R" signifies that it's a radial tire. The "17" refers to the diameter of the wheel in inches.
A 285 60R 17 will replace that
A 285/75R16 tire has an overall diameter of approximately 31.8 inches (about 806 mm). This measurement is derived from the width (285 mm), aspect ratio (75%), and rim size (16 inches). The aspect ratio indicates that the sidewall height is 75% of the tire's width, contributing to the overall height.

No, a 245 tire is 245 mm wide. A 275 is 275 mm wide.

I wonder if it might be 285 gallons!
