Don't go over 20% on your width. 9" divided by 0.0393= 229. 229 times 20%= 274.80. Rear is 304.89. The "whatever you get" you're talking about potentially could be a tire blowing off the rim equaling a not so good day. 275/305 should be fine and safe but some tires will have flex and stuff which will hurt performance.
