Will this Tire fit?

A 275/40/17 will fit on an 8"wide wheel, but you'll get a better contac patch with a 17x9. Most manufactures reccomend a 9" wide wheel for a 275/40


Also the center of the tire is going to were out quicker during regular street use because the tire is going to ballon out at the sides and be taller in the middle because the wheel isn't as wide as it should in reality be.
