I am looking at these tires for my DD after I wear the P zeros that came on it. Personally, I take tires very seriously and before buying my DD I was researching the replacements available
and found Kumho to be one of the options available when tire change due. I think the current reviews are promising, and found other reviews from Europe and Australia to have same impressions.
It may not be the best in category but it may be pretty good for the price, will know with time about long term use as they are new in market.
