No. I'm not trying to be condescending here or to mock you. I am truthfully 100% wrong and stand corrected by you. Please don't take my post any other way. I'm was simply trying to be a "good" loser and give you credit for knowing your stuff!

Fair enough!! A big thank you then from me to you!!!
I first "figured it out" when my father explained how they set tire pressures on his 727 based on total weight of the aircraft and contact patch for the tires. I thought he was nuts when he said 10,000 pounds of weight yields a 100 square inch contact patch at 100 psi.......
Like this thread, it took some explaining and convincing before I relized my dad wasn't nuts.

Hopefully this thread will prove educational.
Thanks again.
Ok, your explanation was beautiful and the math works out perfectly. Most of us are looking for grip during acceleration and hard cornering, both of which involve some sort of weight transfer from front-to-back or side-to-side. Based on the many posts above I've drawn the conclusion that a wider tire provides the exact same contact patch while sitting still, but during acceleration the wider tire provides more grip. Is this correct? I don't really care how much grip I have at 0 MPH.

I think (but google searching wasn't proven to my satisfaction yet) that we can run a lower pressure at the starting line with a wider rear tire. THIS is what I think is the source of extra traction. I used to run about 28psi with my F-1's. I plan on dropping to 25 psi with my new 275's. In theory, I'll have 10% more contact patch at launch and 10% more traction +/- differences in tire brand.
We'll see.......
I wish I were more of an expert, but I must admit we're at the end of my knowledge level. We need someone else to step up who's even more technical than me.
