185/65R15 Tires

What 185/65R15 means

The 185/65R15 marking is three measurements: 185 is the tread width in millimetres, 65 is the aspect ratio — the sidewall height as a percentage of that width — and 15″ is the wheel rim it mounts on.

The numbers for this size

These follow from the size itself: sidewall is 185 × 65%, and the overall diameter is the 15″ rim plus that sidewall twice over. The revolutions figure is what your speedometer is calibrated against — fit a size with a noticeably different diameter and the reading drifts.

How 185/65R15 drives

This is a tall-sidewall fitment. There is a good depth of rubber between the road and the rim, so it rides softly and survives potholes far better than a low-profile — the trade-off is slightly softer turn-in.

At 185 mm it is a narrow tyre, which is an advantage in slush and unploughed snow — a narrow tread cuts through to the surface instead of floating on top of it.
