2003 Cadillac CTS, 2005 Cadillac STS4 1SG
As Ive posted before, Im interested in some 18 inch wheels. The recommended tire size they gave me is 245/40/18, but I notice the CTS V rides on 245/45/18. I want a more performance oriented tire, but also dont want a harsh ride. Keep in mind I live in Detroit with crappy roads. Should I just opt for the CTS V size tires? They are a little over a half inch bigger than the stock size and the stock suggested size. Would this have any negative effects? What would YOU opt for? Thanks.
