I have a 2005 CTS, luxury package. I need 4 new tires. I typically change to snow tires in the winter. It is 4 years old and I only have 20000 miles on it. Although I change to the winter tires, the ones that came on the car are already bald. I do not want to spend a ton of money, but want a decent tire. I have gotten quotes for Cooper CS4, Nexun N5000, Yoko Avid TRZ and some other higher priced one's. I want to stick with the original 225x55x16 size and would love feedback on these tires or any others you may suggest. Thanks!
