Plus mount and balance. If you bought 5 then $120*5=$600. Then $600 plus $100 to mount and balance, so $700 + tax. I was able to do $510 with tires, taxes, mount, and balance for 5 tires. A place here in Houston has Michelin 60k mile tires for $137.50 new plus tax. So a set of 4 would be $595 OTD. I was going to go that route, but the CL deal was tax free for the tire purchase and one extra tire.
