Tire and wheel questions

I am fighting with 275 /60/ 15s right now but I bought the Nitto 555R which has a section width of 11.1 inches which is not working with the 15x8 with 4.5 " backspace , If your going to go with a modern looking wheel you might want to go up to at least a 16" wheel because there isn't many tire options for 15" anymore , the Radial T/A is a crappy compound that has really bad wet weather grip and the 3 brand names that the Cooper GT are sold under are just as bad as the Radial T/A. There is no way you will get a tire the size of mine on the front , you really need to just suck it up and read the sticky at the top of this section that has everybody's combo posted in it , then get a tape measure and do some math on your car, compare the tires you are using now by there listed dimensions to the tires you want to use and get under the car and measure the space your car has .
