What a great exchange of tire info. My rear Kumhos (I think Ecsta LE sport model) lasted about 12,000 on the rear. I hesitated to replace the fronts that still had much tread wear so I purchased 2 rear Kumho replacements to match front. But the front wear indicated I had an alignment issue so I got that fixed. I don't drive in winter snow/ice. I have some issues with road noise using cell phone bluetooth on the highway. Seems that road noise is picked up by the microphone (Kenwood Marine 558bt) so folks on other end have background noise and I have trouble hearing them. Tire Rack reflects $591 for 4 tires OEM CF specs, not bad. I am curious to know any opinions about road noise comparing the Kumho to the G-Max AS 03. I like the tread pattern and the idea of longer life of the G-Max is desirable. Any opinions would be greatly appreciated about road noise! Thanks!!
