you mean a 235/60 r16 being used with 3-235/70 r16? I wouldn't unless it's an emergency. the single tire has a smaller diameter. by 23.5 mm. the 235 part is basically the width of the tire, the 60 and/or 70 is a percentage of that with and that is the profile or height of the tire. so the difference is these tires is 10% of 235mm.
Absoulty not if the 255/70-16 is the OEM tire size. The 215 will be 13% smaller in overall diameter. You should never, ever go over 3% different. You would have to go to a 275/60-16 to even be close to 3% and then it would be 3.5% smaller.
The 235/75/16 is larger.
Yes you can
Can a 225/60R 16 tire replace a 235/70R 16 tire.
The 235 / 65 / R16 is the lower profile tire ( 28 inches in diameter instead of the 29 inches in diameter for the 235 / 70 / R16 ) Both size tires are the same width
A 235 85 16 tire is 31.72 inches in diameter and has a 15.86 inch radius and a 99.65 inch circumference
I guess you can - 235 85 R 16 is a bit narrower and taller. but not vitally. so it would fit
yes
A 235 60 16.
Can you? Yes. Should you? No. The 235 will be 3.67% smaller. This will adversely effect your ride, handling, speedometer, and braking.
28 inches
Only if you have 16 inch rims that fit the Durango. You can not put 16 inch tires on 15 inch rims.
