Car originally had size 13 tires in front ex changed to14. Can 13s be replaced?

What is your question?

Did notice after the change, car did not run as smoothly. Feels like I have something heavy in the car. Never occurred to me that the tires were a different size in front.

What makes this problem better or worse?

Car started to run heavy(?) not smooth

How long has your 2005 Hyundai Accent had this problem?

Since tires were changed 6years ago, didn’t realize till it was pointed out when buying new ones
