hello I am new to your website and have recently purchased a 1999 V6 mustang convertible for my wife. In the purchase was included 4 aluminum wheels 17 x 9. I am interested in buying some tires for these and was thinking 245/45/17 for the rear and 225/45/17 for the front. I am interested in your opinions... btw the car is entirely stock in case that is important.
