New Tires or new Wheels?

I have cooper cobra on my dart. The only thing i don't like about them is the tread pattern is very aggressive, looks abit like snow tires. Had BFG in years past, don't feel any difference. I don't do any performance driving so they work great for me. In hindsight I should have gone for the twice as expensive red lines to be more OE correct ( I'm into that)
