The BF Goodrich Long Trail tires that come on the Santa Fe ( US ) are off the shelf, not OEM. You can buy them at www.tirerack.com

They do not seem like a cheap crap tire. When it's time I might buy them again since they Santa Fe handles nicely with them. A possible better choice is the Michelin Cross Terrain. They are probably a better tire. Check out the ratings at tirerack.com
