I'm thinking about putting some wider tires on my 1969 Chrysler 300. Right now, it's running 225 75's on 15 inch rims. Whitewall looks pretty sharp, but they look like bicycle tires. I did some figuring and looks like 255 60s or 235 70s are pretty close to outer tire diameter to maintain the drive height. Will they fit? I'm really leaning towards the 60s, but not sure if they'll fit and still allow me to make decent turns. Turning radius on the car is already pretty wide, so I don't want to make it worse.
