I was running mine in the lower 40's at nats, and I then went down to the upper 30's. CLyde said that he had best results with 30f 27r, but you have to be careful with the sidewalls then.

The tire fits, but it does kind of look like a really fat guy wearing too tight of a belt...
Cito, thanks for the information on pressures!

at 30/27 just make sure you take a healthy dose of dramamine several hours before you run ...

I never ran them that low, but I am going to try it at least once given that Clyde and John V did the most in terms of research with the tires. At the lower pressures that I have tried, they do feel a bit squirmy.

The lower the pressure, the faster we went. I wouldn't expect them to last very long at 30/27, especially if you're at all prone to overdriving.

Update:
I ran the fat boy Hoosiers, started at 35 all around, let them climb to about 36 and then evened them out at that level. Car felt just fine, on a course with a number of slaloms and a couple of turnarounds and sweepers. The thing that makes these initial impressions of less value is that it was about 50 degrees and the course was damp in some places, so, even with a co-driver, we never got enough heat in the tires to get more than 2-3 psi pressure increase in a single run and the tires never reached a stabilized pressure.
So, not enough information to really judge what's what, but a pretty encouraging first effort. If the car feels about the same next weekend, I'm going to an adjustable front bar and taking some camber out of the rear, in all likelihood.

he has a codriver with an unlimited supply of "Get Out Of Hoosier-Jail Free" cards
They didn't work for at Packwood last year, but perhaps my setup didn't favor them. The course we ran this past weekend IMO was about as favorable for them as was possible, nothing like Packwood or a typical Pro course/conditions

The jury's still out, as far as I'm concerned. It'll be clear in about 6 weeks whether we've made them work...
They did feel great in the slaloms this past weekend, which I find encouraging

I would'nt call the course or conditions typical, despite running the front bar stiffer than I've ever run it before our car was still very loose

Interesting comment about your front bar being set stiffer and still being loose. I wonder if that indicates that my car will see push on a completely dry, warmer surface? I now have -1.8 front camber and the rear shocks at full stiff, with the stock front bar. Maybe that combination is enough to get the front to stick...

I dont think its the over heating issue... i think its the issues of too much tire on a 8" rim. And how much overheating is an isssue on a 30 second pass? Its not like he's doing a full 20 min track event... where it would be a much larger factor.
Someone earlier said its all about getting more rubber down, but if the rubber isnt making contact, is just bubbling, and is weighing more than the 245/255 tire but with the same contact patch - then yeah, maybe not such a great idea.
Then again... im just a noob at this, so whatever.
