To answer your question: not very well. We've got a couple of guys here running around with 26's on older '80's Caprices. Seen 'em in the local grocery store parking lot, out in the middle of no where, where no one else parks. Just to take a long sweeping turn it's like watching a tractor trailer. Actually, I think a tractor trailer could make the turn tighter.
One was coming off the gas island. He had to pull forward and back up a few times to make it.
