Your problem isn't the SIZE of tire. It's the TYPE of tire. The Dunlop SP5000 is an all-season tire, and not a particularly good all-season tire at that. At moderate to warm temperatures (when there's no snow or frigid cold), all-season tires don't perform very well, not even as well as inexpensive summer tires. So you really need to get BETTER tires, not WIDER tires.

For your car, on 15" wheels, the proper tire sizes are either 195/55-15 (1.0 percent larger diameter than stock) or 205/50-15 (0.6 percent smaller). Anything larger will probably rub on the wheel wells.

There are a lot of tires available in those sizes, particularly 205/50-15. For a high-horsepower application, assuming you care only about dry traction, you don't mind if the tires don't last all that long (say, 9-12K miles), you don't care how much they cost, and you're not driving in winter conditions, then I recommend you get the Falken Azenis RT-615 in 205/50-15, which is the right size for the 15x6 "fat fives" on your car. This is the tire with the highest dry traction you'll find anywhere in a street tire. They're $78/tire at Vulcan Tire.

 

sry 2 jack this, but first of all i have 205/45/16, my fronts went bald(hankook k106), so i ordered 2 dunlop sp sports, to replace the front. My question is; is it bad having 45 instead of 50/55 ? , and also having 2 different types of tires ? ? and wat does v-rated and 200 treadware mean . . . . im assuming the tires i just bought wont last long at all.

It's NOT a good idea to have different sized tires (unless your car was designed for that) and it's NOT a good idea to have two different types of tires. That makes the handling very unpredictable. Your car might oversteer in some conditions, understeer in others, etc. NOT a good idea.
