Who owns a set of these? What is your experience? My mom's car is down to 4/32". With the current sale at DTD, I can get these for Chinese Tire pricing. Normally I'm a bit of a tire elitist and stick with Michelin, but my mom won't be able to tell the difference anyway - so I may as well save the $350 over Michelins. Based on the Consumer Report reviews, they appear to the decent mid-grade tires. Thoughts?
