Have you had any issues with the traction control or any warning lights? Your overall outside diameter is quite a few mm larger than factory if you went up to 275 wide and stuck with the 55 aspect ratio. I had a problem on a car when I was 3mm over factory diameter. Keep in mind your speedometer will be slightly off as well. If you don't have any issues after a couple months let us know. This could be an option for me in the summer months!
