I replaced my stock size with some Bridgstone Potenza A/S Pole Position tires, size is 245/45-17. Even though they are high end and pretty expensive i think the handling has diminished slightly over the stock size, especially corning ability. I dont know what others have experienced with different size tires but i will go back to the stock size after my current set is worn. There is a certain turn on the highway that i take almost everyday. Its four lanes and the inside lane is really fun to take at a decent speed, i used to be able to take it going about 70 mph and it would hug the road perfectly. With the new size tires it actually handles alittle unpredictable. I dont feel comfortable taking that turn going over the speed limit now.
P.S. - I have had three tires become defective with one literally falling apart. I questioned the tires but the size difference might be whats causing it to fail. Just a thought when your going away from stock size.
