That is the aspect ratio , or ratio of width to height of the tire
the 195 is how many milimeters wide the tire is, the /65 stands for a percentange of the 195, so the side wall of your tire will be 65% of 195, and r/15 is a 15 inch rim size ,$ushil,india
195 65r 15 is the tire size. 65 is width and 15 is rim size
Yes, that is reasonable.
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.
No a 70 aspect ratio tire would be taller than a 65.
The 65 series tire will be wider if both sizes are equal. Example is 205/70-15 versus 205/65-15. The 65 series will be wider but have less overall diameter. The series of the tire is a height to width ratio. A 65 series tire has a height that is 65% of the width, so a 205/65 tire is 205 millimeters wide and 205*.65=133.25 millimeters tall (rim to tread). Since it's usually not recommended to change tire diameters, if you want to go wider or narrower you need to change the width and series. For instance a 205/70 will have almost the same diameter as a 225/65.
This tire size should be 195/65/R15 (89S) This tire size should be 195/65/R15 (89S)
Yes, the smaller the aspect ratio the wider the tire.
You mean "shakes at 65?" If so, a possible cause is an out of balance tire. I would check that all tire lug nuts are there and tight and check for warped rotors. Check tires for blisters and check the steering linkage for worn parts.
Yes, you can.
No, this is a bad swap. If you want to go with a 65 series tire then install a 275/65-15 which is almost identical in overall diameter.
The tire size is usually 185/65/14.
