Up to 22,500 kms, approx, now with about another 6,000 - 8,000 k's of rubber left on these and have worn extremely evenly - rotated every 7K. Definitely shoeing my iron horse with KU31's again. They give great feedback enabling excellent driving predictability; stable and constant contact in wet or dry; cut through standing water without hesitation; have never aquaplaned. Brake in a true straight line. Are getting a bit noisy now though, but only noticed this after 15,000 kms. I drive long country distances interstate, (1,000's of kms per journey), regularly, on uneven Australian secondary back routes. With little to no traffic I can happily keep up a steady 130 - 150 kms/hour on these road surfaces without bouncing all over the shop. Honda gives a slightly hard sporty ride, but these tires are forgiving while instilling driver confidence with their firm footprint on the bitumen. Can cruise corners very comfortably 30 to 40 kms/hr above the sign-posted recommended speed, without any kick on the apex. Have never let me down. Admittedly, I have never driven them on ice or snow. My tire wear seems better than what some others have posted here, but I think is probably more due to car's ATTS suspension ( ), which saves tires. Obviously, wear will vary depending upon vehicle, maintenance and driving style. I agree with previous poster that these tires are under classified as they punch well above their weight in terms of price and classification - are up there with grand touring/medium performance tires. Well done Kumho.
