Tire size question
 

I just purchased some weld draglites for my 2003 Chevy Blazer Xtreme
the rears are 15x8 the fronts are 15x6. My question what size tire will fill the wheel well without rubbing. There is so many sizes to choose i'm not sure which one will fit. Blazer has stock suspension. Also how wide can i go in the rear.

16 in. Prolly would be a better bet because there are more combinations available. Can you send them back and get the same size front and back. Blazers understeer quite a bit so a bigger tire rim in the front will help.
