A 225 70 R16 or 225 75 R16 Would fit the bill quite nicely and are little bit cheaper than the 215's. Alot of smaller SUV's use this size and it is quite common. My Father's shop sells Mastercraft tires, they are basically a generic Cooper, I've had quite good luck with them and they are about 10 to 20% cheaper than most name brand radials.
