Nankang car tires. Any good?

Need to buy my sis a new set of tires for her car.
Seems Nankangs have good reviews and looking at under $300 for a set vs about $500 for the "name brands."
Any one with personal experience with Nankang tires?

Also considering a set Nankang mudders for my old CJ5. It doesn't get driven but a couple times a year around the block and on the trails and the 25 year old tires that are on it got more cracks than a shattered windshield.
