Bought my KH25s used with alloy wheels & half tread. Tho they are very low profile (40) aspect tires, they are smooth, moderately quiet, & steer just OK on the front tires. They track on-center strongly, to the point that a very little steering wheel input ISN'T ENOUGH to begin turning the car! Wear is quite low. Tho half tread, I've traveled 16,000 miles, with 5000 to 10,000 miles remaining. While not being careful, the low aspect tires easily cause curb rash. Altho I've hit fair sized bumps, I haven't gotten any other alloy damage than the curb rash.
