I suspect they are the usual Hyundai 5x114.3 with 67.1mm center bore and 12mm lugs. I could be wrong, but considering that the Sonata/Elantra/Tucson/Tiburon/Genesis have shared the same pattern for a decade, I think that Hyundai wouldn't throw a wrench into the works by switching to something different.
Can't say the same for GM, though. The Cavalier used 5x100 (the compact/midsize standard since the X-cars of 1979), the Cobalt changed to 5x110 (the Saab/Opel standard used because GM cars of the last half decade, including Saabs, are rebadged Opels), and now the Cruze changed to 5x105. Am I the only one laughing at the drunken product planners who are changing their bolt patterns by 5mm-10mm every 5 years so that you can't throw a set of snows on some junkyard rims from a 2004 Chevy Somethinorother and bolt 'em to a Cruze? Ford is almost as bad because they have their 5-lug "Volvo" rims and their 5-lug "Mazda" rims (Ford cars are Blue-Oval-festooned Volvo and Mazda products), so finding a generic OEM rim with a blue oval on the center cap is no guarantee it'll bolt on.
If you know anyone with a recent (less than 10 years old) Elantra/Sonata/Tiburon, ask to borrow their donut spare and try to bolt it onto your Elantra. Make sure the lugs are centered in the holes on the steel rim and that the center bore fits snugly over the hub. If it does, you're in business - it'd mean the 2011 Elantra is the same 5x114.3 pattern as all the others. For the grief of a "simulated changing a flat", you can know for sure if wheels you purchase will fit properly.
