Can 185 65 r14 substitute 195 70 r14 tires?

No, there is too much difference in overall diameter at 5.17% smaller which is unacceptable. You should never go over or under 3%. A 195/65-14 is extremely close to being acceptable at 3.10% smaller. Your speedometer will read 2 mph slow and you will get slightly less fuel mileage. Just make sure to replace them in pairs of all 4 if you decide that is what you want.
