Replaced my 30-35% treaded Kumho's today with Yokohama's from America's Tire. I was tired of the continual flat tires with the Kumho's. Had one blowout and 3 flats. So although a little early to replace my tires, it was time in my opinion. The YK-520's are smooth and quiet. Appreciate the recommendations here. I felt like I got a new car today instead of tires. It drives sweet (and quiet).
The only complaint is there are more wheel weights on the tires than Kumho's had. I told America's tire they should have paid attention to the yellow and red dots on the tires. As far as I know, the yellow dot should be placed at the valve stem or opposite the valve stem depending on weather the valve stem location is the lighter or heavier part of the wheel. So they just mounted them however they happen to be orientated - probably influencing the amount of required weights to obtain balance. I told them to remount them and they said I was "unreasonable" and the Manager tossed me the keys telling me to have a nice day! Maybe I am too picky but I do expect people in the tire only business to pay attention to the manufacturer marks. Too picky?? Found this link below:

Here is some of the text (see web site for full details):
Observe match-mounting procedures
To facilitate proper balancing, Yokohama places red and yellow marks on the sidewalls of its tires to enable the best possible match-mounting of the tire/wheel assembly. There are two methods of match-mounting Yokohama tires to wheel assemblies using these red or yellow marks:
Uniformity (red mark)
Weight (yellow mark)
Uniformity Method
When performing uniformity match-mounting, the red mark on the tire, indicating the point of maximum radial force variation, should be aligned with the wheel assembly's point of minimum radial run-out, which is generally indicated by a colored dot or a notch somewhere on the wheel assembly (consult manufacturer for details). Radial force variation is the fluctuation in the force that appears in the rotating axis of a tire when a specific load is applied and the tire rotated at a specific speed. It is necessary to minimize radial force variation to ensure trouble-free installation and operation. Not all wheel assemblies indicate the point of minimum radial run-out, rendering uniformity match-mounting sometimes impossible. If the point of minimum radial run-out is not indicated on a wheel assembly, the weight method of match-mounting should be used instead.
Weight Method
When performing weight match-mounting, the yellow mark on the tire, indicating the point of lightest weight, should be aligned with the valve stem on the wheel assembly, which represents the heaviest weight point of the wheel assembly. After match-mounting by either of the above methods, the tire/wheel assembly can be balanced.
