The Lifeliner GLS were a good set of tires which prompted me to stick with the Cooper brand on my next set. They were solid in the sense that no issues were involved except for nails and screws throughout the life of the tire on the vehicle. The noise was barely noticed and the handling was moderate compared to other tires installed before. My regular driving conditions were dry but these tires were good on wet surfaces as well.
The only complaint with these tires is the treadwear. Only lasted me 24000 miles with regular tire rotation and required tire pressure on each.
