yes. but i would change all four tires to that size or at least the front two or back two. but also realize you might have some camber issues by doing this swap. Also your speedometer will be off about 2 mph.
Yes, you can
195 65r 15 is the tire size. 65 is width and 15 is rim size
Yes, the 65 tire is only slightly taller.
whatv other tire is compatible with 225 65r 16
That is not a tire size.
No, there is a 3.15% difference in overall diameter. This will cause your speedometer to be off 2 mph.
No, if you are going to a 70 series tire then you will need to go with 195/70-15.
The 65's will stand taller than the current 60's because this number represents the height of the tire as a percentage of the P195. Always consult your local tire dealer specialist, their advice is usually free of charge.
That is an acceptable swap but a much better choice would be 245/60-17 which is an excellent swap.
P205/65R-15.
185/65R - 14
Yes, they will, - and if ever they won't , all tire shops will tell you. -They don't want to be responsible for fools fitting wrong tire/rim combinations.
