Hi
I want to change the rear tires this weekend,it has 225/50/16 'w" rated right now.I was thinking of replacing it with a lower rated tire at 148 mph V" rated,something economical.Whats your take on not using ultra performance tires.which place would u recommened in Lousiville for tires/alginment other than dealership.

thanks for help in advance
