Sure Why Not!
Not without a lift. It will be too tall
255 = width in mm 65 is the aspect ratio 65% of 255 mm in sidewall height. R = radial tire 16 = 16 inch diameter rim so the 70 tire is 1 inch taller overall and at a speedo reading of 60 you will be going 62.1mph
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.
Absolutely not. You will increase the diameter of the tire/wheel from 30.1" to 31.6". This 1.5" difference will cause your speedometer to be way off. This will also adversely effect the handling and mileage of your Ford. The closest thing to OEM you can go is 265/65-16 which will still be .5" off. Stick with the OEM size.
NO 255 / 245 - 70 / 65 - 17 at normal lift ....
Yes, you can.
255-245 / 65-70 /17 in normal lift
The 205/70/r15 is 26.3 inches tall. The 215/65/r16 is 27 inches tall. Never mix different size tires on different rims.
what is the diameter difference from a 205/65/16 vs. 225/60/16
Switching from 255/70-16 to 265/70-16 will cause your speedometer to show 58.9 mph at a true 60 mph or a difference of 1.1 mph. A better switch would be from 255/70-16 to 265/65-16. Your speedometer will be off .9 mph too slow.
255/65 = 3hours 55minutes 23.1seconds (rounded)
215/65 R16
