255 mm wide versus 245 mm wide. Can not answer for height since the second tire you listed as a 0 for the next number. The second number in a tire size is the aspect ratio of the side wall. If it is 65, that means the side wall is 65% of 255mm in height.
No number specifically indicates the height. You can however figure the height with a little math. As in 245/70-15 the 245 is the width of the tire in millimeters. The 70 is the aspect ratio which means the tire's height is 70% of the tires width. So on this example the height of the tire is 171.5 millimeters.
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.
235 / 70 / R16 is : 29 inches in diameter / section width 9.3 inches / section height 6.5 inches --------------------------------------------------------------------------------------------------------- 245 / 75 / R16 is : 30.5 inches in diameter / section width 9.6 inches / section height 7.2 inches
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.

It sounds like the tread width in millimetres
235 / 65 / R17 is ( 29 inches in diameter and the tire section width is 9.3 inches ) 245 / 70 / R18 is ( 31.5 inches in diameter and the section width is 9.6 inches )
A 235 / 85 / 16 tire is ( 31.7 inches in diameter and has a section width of 9.3 inches ) A 245 / 80 / 16 tire is ( 31.4 inches in diameter and has a section width of 9.6 inches ) So , they are pretty close in physical size , but I don't know about the weight carrying capacity ( the 245 tire , with the lower profile . is 3 /10 th of an inch smaller diameter and 3 /10 inch wider )
245 and 225 are the first numbers in a tires measurement and they simply tell you how wide the tire is in mm. So a 245 is wider then a 225. But which is taller? This depends on the second number which would be something like 245/70 or 245/75 and the same goes for the 225/70 or 225/75 and there are many different combinations. This second number tells you in a percentage what the sidewall height is compared to the width which is the first number. So for a 245/70 tire it would be 70% of 245 = sidewall height, in this case that would be 171.5mm and a 245/75 would be 75% of 245 = 183.75mm so in this combination the 245/75 is taller than a 245/70. So if you had a 245/60 the sidewall height would be 60% of 245 =147mm and if you had a 225/75 the sidewall height would be 75% of 225 =168.75 which would make it taller then the 245, so as you can see it is the second number which gives you the calculation needed in order to get the height. Of course the last number in tire dimensions is the rim size such as 245/70/16 would mean it is for a 16 inch rim and this will affect overall height of the tire compared to a 245/70/15 which would go on a 15 inch rim.
A 225 75R 16 tire will fit on a 245 75R 16 rim. The only difference between the tires is the height of the sidewall.
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.
Here are some instructions on how to calculate it 1 Locate the tire size on the sidewall of the tire and write it down. The tire size will be in a form that looks like this: 245/65R17. There may be additional letters before or after the size, but this information is the size descriptor for the tire. 2 Calculate the section height of the tire by multiplying the section width times the aspect ratio. The section width is the first three digits of the tire size in millimeters. The aspect ratio is the two digits after the slash before the R. In the example above, the width of 245 millimeters would be multiplied by the aspect ratio of 65 percent, resulting in a section height of 159.25 millimeters. 3 Multiply the section height times two and convert to inches using a multiplication factor of 0.03937. For the example tire size, the multiplication would be 159.25 times 2 times 0.03937 giving a tire height of 12.54 inches. This height is the measurement of the tire above and below the rim. 4 Add the tire height amount to the wheel rim diameter. The wheel size is listed after the R in the tire size. In the example the tire goes on a 17-inch rim. Adding the tire height to the rim diameter gives a total tire diameter of 29.54 inches.
