The standard tires are large 185/65R14 all-season radials.
Try finding a 13" tire anymore, nevermind anything smaller. 14" tires are not "large" by today's standards by any stretch of the imagination. Suitable, yes, but not large.
Otherwise, decent review. Both the new Accent and the Rio5 look great in person. Didn't really take a good look, but from the outside I thought "hey, that's a nice looking car". Add that to Hyundai's increasing reliability, warranty, and price and you've got a real winner.
