Yes, this is an acceptable swap.
No, the 185 70 r14 tire cannot be substituted for a 175 65 r14 tire. The 70 series tire has a larger diameter and is not recommended that you substitute on a 65 series tire.
Yes they can. You do realise this gives less tread on the road, which is not always a good idea,
No
Yes, they can
Yes, they can
Please give the whole number, NOT just part of it. Whole number will be something like this - P185/60R-14 95H . IF the last number and letter are same then it is a substitute
You can although you will be putting a much smaller tire on and it'll cause your speedometer to be off by about 4 1/2 mph at highway speed (speedo reading 65 actual speed would be around 61 1/2 mph). A better substitute would be a 175/75.
No, this is not a recommended substitute. The 70 series tire will be 3.02% larger in overall diameter. Your power, and fuel mileage will be effected. Your speedometer will read 58.1 at a true 60 mph. If you wish to go to a 70 series tire then go with a 175/70-14 which is almost the exact same diameter.
Yes, this is an acceptable swap as there is only 1% difference in overall diameter between the 2 sizes.
no
Yes, but your speedometer will read 1.5 mph fast.
