You could, but why would you want to? Find a set of 215/55-17 tires that were cheaper? That is not a good justification for using something other than the recommended size suggested by the automaker. The engineers and designers at Honda spent a ton of time, energy and money determining which size tires would perform best on your Accord. You should trust their judgement.

You can but increasing the aspect ratio (going from 50 to 55) will increase the overall diameter and circumference of the tire. An increase in the size of the sidewall can make the steering feel less responsive. The increase in the overall circumference of the tire will also throw off the speedometer reading.

It's recommended to stay with the stock tire size determined by the manufacturer for the best performance.
