I have to keep my ProStars tied down or else they float away :D
I ran around all last summer on those wheels, skinnies up front, and the Hoosier QTP's on the rear. Car actually rode / drive nice (as long as you drove like there were skinnies on the front). Toward fall I threw the Waffle stars / 225/50/16's on it and it drove like ass. I could feel those wheels on the front every time the steering wheel moved. Not a direct comparison to your change, but an extreme example.
Well, the official bathroom scale weight of a 17x8 Ford Bullitt with a Nitto 555 245/45/17 is 50lbs on the nose.
I'll report the weight of the Cobra R's and 275s on Saturday if I don't incur hypothermia or frostbite.
If they're somewhere near 60lbs, I would consider that a significant amount of added rotating, unsprung mass. 20%.
Haha the offical bathroom scale! That's what I used!
i think my cobra r are 65 pounds??
