How cheap are the Kuhmo tires?
the Kuhmo Ecsta EX are slightly cheapper then the D1 stars (save $7 on 225/50/16)
180 tread wear vs 200 (not the same tire company so not very valid comparison)
But I'de keep them in consideration.
I've been running a set of Kuhmo ASX's on my rally car for DD usage. and i've been very very amazed with this tire. They have great dry grip, awesome wet , snow, mud, and dirt traction as well.
I've been very amazed with their sidewall , and overall tire quality. If they can make a super cheap all season tire with such puncture resistance , and strong side walls. i would figure that their tire aimed at street touring would be top notch as well.
my bridgestone RE01Rs took a lot of abuse too with out issue. (rocks, ruts, jumped once)
