The type of lug nuts that you need Will are also dependent on the wheel type that you are using. Those shank-style wheel nuts are to only be used on wheels that are designed to take them. You can usually tell when you put the wheel onto the hub and can see quite a bit of space between the bolt hole on the wheel and the actual hub bolt itself. So depending on the aftermarket wheels you have, an acorn-style wheel nut may be more suited.
You have genuine Toyota wheels though right? There is a good chance that these need the shank-style nuts. If you started off with steelies, then your stock lug nuts were most likely the acorn-style as well and therefore you would most likely need to pick up some shank-style nuts.
Edit: Obvious information, but just in case.... these are the acorn-style... also referred to as tuner style:
