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.
Only if you change the whole set, there will be a height difference.
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.
28.8 height and 9.25 wide
The difference between a P225 75R 15 tire and a P235 75R 15 tire is the width of the tread and the height of the sidewall. The first number is the tread width in millimetres. The second number is the aspect ratio. That is the height of the sidewall as a percentage of the tread width. So it would be 225x75% fir example.
That is the aspect ratio , or ratio of width to height of the tire
Yes, if you have the correct width and back spacing. You will need a tire with a lower profile (sidewall height tire) to maintain tire diameter/height, or your speedometer will be inaccurate.
According to the ranger station . com the 285 x 75 x 16 tire is ( 32.8 inches ) in diameter
Depends on the shape the other tire is in. Ideally - especially on a live axle - you want to keep no more than 2/32nds height difference between the tires.
P means passenger tire, 185 is the tread width, 70, or 75 is the aspect ratio of sidewall height to tread width. R is tire bead diameter. Same as wheel size. A 75 sidewall tire is taller than a 70 series.
The height difference is quite significant, but what does height have to do with it?
There would be no detectable difference.
