I had a nail in one of my tires, so I went down to discount tire company. I had the Kuhmo Supra 712 in mind. I brought a print out of a website with the price at $79, so I got ~$25 off each tire. Well the guy sold me the tires and I paid, but they did not have them like they had thought. So he gave me the Yokahama YK420 for the same price, but they only had them in 225/55r16, so I got those.
Is there a problem going from 215/55r16 to 225/55r16?
I like these so far, they are way better than what I had before(bald proxes).

No problem, per se. Just be aware that since the overall diameter of your new setup is larger, your speedo/odo will be slightly off. It shouldn't be too bad - that's not a huge leap you've made, but expect the speedo to be indicating approximately 1-2 mph slower than you're actually travelling at around 60-65 mph.
