I see they are 185, can a person put a 195-60 in its place?

The overall diameter of the 185/65R15 tire is 185 divided by 25.4 times
0.65 times 2 + 15 which is 24.47 inches. The diameter for the 195/60R15 tire is 195 / 25.4 x 0.60 x 2 + 15 = 24.21 inches. Since the latter is only 1% smaller, the 195/60R15 tire should work fine - the odometer and speedometer readings will read 1% too high, which is within the tread depth difference between new and old tires. The 10 mm or 0.4 inch wider tread should not cause any problem....and I'm running 205/55-15's on OEM alloys (re: 97SL2)
