edgeracing.com will give you the tire weights for the tires they sell. That is, if tire weight has any bearing on what you buy! Their prices aren't bad either. S-03's tend to be the heaviest tires. I know a lot of people like ES100's, but treadwear might not be as high as you want.
S03s wont last as long as ES100s, while being grippier.
Kumho MX, BFG KD, Bridgestone S-03.
those are the 3 you should be looking into.
Falken Azenis are good, but don't come in a size useful for a cobra.
