I have a 2016 Base Cayenne and my car is in for service and I need four new tires. The dealer can sell me Goodyear Eagle LS2 255/55R18 tires for $1213 (includes installation) and about $250 for an alignment. Sears can sell me Goodrich Adcanatge sport for $854 and that includes an alignment. So Sears is $600 cheaper. The Eagle LS2. Has a tread rating of 400 and traction of A. The Sears Advantage Sport has a Tread Rating of 660 and Traction B.

Any thoughts on which tire is better? I need to decide tomorrow.

Thanks
