200 series tires on 5" and 5.5" wheels will actually present less contact patch and a narrower profile at speed than the 180 due to tire growth. Not to mention that due to the tire growth, they are more prone to ripping out the rear wiring harness. I have also personally witnessed a friend go into a high speed tank slapper above 90mph as a direct result of slapping on a 200 series Avon Venom. We warned him, he didn't listen.... Wobbles set in any time he went above 80mph. He decided to push it through.. Down the highway he went. There are really tons of threads on this subject... why this question is still being raised, well... it honestly amuses me.
