It sounds like the tread width in millimetres
No, a 245 tire is 245 mm wide. A 275 is 275 mm wide.
If you mean a 245 tire there is not enough information to answer. Things that you left out of the question like, year and model Jeep.
The tire size 245-45-17 indicates the tire's width, aspect ratio, and diameter. The first number, 245, represents the tire's width in millimeters. The second number, 45, is the aspect ratio, which shows that the height of the tire's sidewall is 45% of the width. The final number, 17, indicates the diameter of the wheel rim in inches that the tire is designed to fit.
To find the height difference between a 245/75R16 and a 245/70R16 tire, we need to calculate their overall diameters. The formula for the overall diameter is: (section width × aspect ratio × 2 / 25.4) + wheel diameter. For the 245/75 tire, the diameter is approximately 30.5 inches, while for the 245/70 tire, it’s about 29.5 inches. Therefore, the 245/75R16 tire is about 1 inch taller than the 245/70R16 tire.
A 245 tire will not fit directly on a 255 tire, as the numbers indicate different widths. The first number represents the tire's width in millimeters, so a 255 tire is 10 millimeters wider than a 245 tire. However, you can mount a 245 tire on a wheel that accommodates a 255 tire, but the overall performance and handling may be affected. Always consult your vehicle's specifications and a tire professional for the best fit and safety.
Doubtful, since the radial is bigger on the r17...
There were two original tire sizes for this car. 245/70R16 245/75R16
It is 245 mm wide at tread.
Yes you can
Yes you can
Yes, you can replace a 245/75R16 tire with a 235/75R16 tire. The first number (245 or 235) represents the width of the tire in millimeters, so the 235 tire will be slightly narrower. The second number (75) represents the aspect ratio, indicating the height of the tire sidewall as a percentage of the width. The third number (16) represents the diameter of the wheel in inches, which is the same for both tires. Overall, the 235/75R16 tire will be slightly narrower but compatible with the 245/75R16 tire size.
The biggest stock tire I have seen is a 245/70/16
