Starting to check out tire prices for the fall when I'll need a new set, noticed Kumho tires tend to be priced better than most others, are they any good? I know they're Korean and just want to make sure they're not junk, and priced low for a reason, low quality! I don't need top notch tires just decent ones that are reasonably priced and these seem to fit that description, unless anyone can advise me otherwise--Thanks!
