Did not want to head into my local Discount Tire in the middle of Saturday afternoon with a half flat tire for repair, but that's what we did. Car had some Yoko TRZ on for 7 years, but the S70 is a pretty heavy car for 195/60-15, so even with 5/32 left they were about done anyway. Service writer said 1.5 to 2 hours for a flat repair. How long to mount four new tires? Same wait time. Went with the GT's as the car sees about 4K miles per year these days. DT reviewers on their website rate them fairly well; Consumer Reports also. We will see. I will put up a report in six months.
