is who I bought the rims from. Great company and customer service. I definitely recommend them.
rhkII: P225/45R18 I was expecting the ride to be more rough compared to the 17" Luxury rims I had, but it rides the same and is still smooth and quiet. Sorry for not posting this sooner, but maybe you can do the upgrade after your run down your new Primacy's. You will be very please with the look and ride. If you don't mind me asking, where did you buy your Primacys? Just an FYI to everyone that Discount Tire does match online prices. Just show them the link on your phone and they'll match it. I saved myself $180.
