tires

if i go from 195/65/15 to a 195/60//15 tire can it do harm to the car in any way

 

It probably should be ok. Most vehivles are designed to go up or down two sizes because they offer different sizes from the factory.

You will lose a little bi of height because a 60 series tire sets a little lower than a 65 series does.

 

You are.going smaller usally everyone one goes bigger

 

Your speedo will read faster than you are actually going.

 

Not sure your poll answer choices are meaningful.

Seems like a 1) yes, 2) no, 3) I don't know either, 4) figure it out for yourself using the tire calculator 5) Let me invite you to my safe place would have been better choices.

Based on the size, you must be asking about a Miata. The 60 will be an improvement. But a 205 x 50 would be even better.
