Man these tire threads make my head spin....I have .1 GT3RS wheels (8.5/12) on my TT and have thought about going 245/325, but the more i read the only thing i know for sure is the 235/305 is the conservative call. Besides having more contact area for traction, specifically in the rear, and the tires being more expensive, what are the other advantages/disadvantages of up sizing? Considering MPSS in both.

"...steam, my bad. i meant to type 26.7 for a 325 30 19. not 27.2"
Steve, that makes quite a bit of difference; the differential is then 3.48%. That seems to pass the reasonableness test (if there's actually any such thing).
John, the problem is there does not seem to be generally agreed upon parameters that confer "safeness" on this topic and as my wife likes to point out, I've already had my Porsche mulligan and can't afford another $20K+ debacle. Insofar as the "math getting ugly", well, that happened some time ago! What a hobby.......Hope to catch a break in the weather and get to the track in October.
Off Topic: Saw where Ryan ran a 2:00xx last Sunday. Was that on the new Super Sports? If so, Simply Amazing!! He's got talent!

I did! Actually, (not to make myself look good,) I had a severe crack on one of my rear rotors reaching the outer edge losing my braking confidence. I didn't push the straights like I normally do with this issue.

That's exactly why I said to stick with OEM diameter ratios. Doesn't matter if it's an 18 or 19 wheel as long as the diameters are pretty much the same as OEM. The October DE will be a good turn out. Hopefully the wx will hold and you can make it.
Yep, Ryan ran on the Super Sports. Those are great tires. From what I have heard they are just below the performance of the Sport Cups but wear like iron. I've driven Ryan's car out there before he put the Super Sports on and it was solid. I'm sure it's even better now. Chris did a great job setting it up and it feels great. On top of that, Ryan is a quick learner and a great driver. I'm betting he'll get into the 59s next time out if it cools off a bit. The time trials on Sunday were fun. I was just very hard to get heat into the tires with only one warm up lap. Take a look at the picture below taken on my second hot lap. On my first hot lap I lost traction at 80mph out of turn 12 all the way to the cork screw. That cost a full second and was a bit hairy. 2nd lap was better as the tires heated up. Fun weekend overall...

Still managed to kill my lap time.
I bet your speedometer was at 130MPH, What the hell were you doing?
