Yep. It is all in the tune. Glad you are loving the corn juice.

I don't believe I have enough driving time yet to make a good decision, but so far I am pretty happy with my setup of 225 and 255. In fact I don't see any reason to change my 225's in the front at all at this point, they work great and feel good. However, I am always paying attention to how my 255's hook up in case I care to go to 265 or 275. Beyond pure curiousity I don't see a need to do it at this point. Maybe I will just move up to RE11 rubber instead of my Pilot SS's. With @whitefrs saying he is content with 245's and how well my 255's do, going bigger may not be as much of a help. But the tinkerer in me cant help but want to try and see.

I think 245 or 255 may be a perfect compromise with 400hp. Of course a part of me is thinking of doing a hub conversion to 5 x 114.3. Moving up to 275's (or bigger) and getting a BBK. But to do this I will also need coilovers (next on my list). The bad thing is, you could do all that just to find out you didn't really gain anything or worse...you changed the car too much and now it has lost it's fun on the open road. And, right I am loving my car so I am not motivated to take the risk. 245 - 255 I think is the safe and easy answer.

I noticed a LOT of rolling resistance when I went up to 255. I'm on a square 18 X 9 setup, but I've been considering buying 4 more of the same rim I'm running in a smaller size, maybe 7.5 or 8, run staggered, and have a second set all around for winters.

No need to do a hub conversion to go bigger. That won't get you anymore clearance. I still think 265s are the way to go.

Hmmm. I didn't really notice to much rolling resistance a little. What I did feel was a heavier steering feel. I am only running 225 in the front (lighter weight than stock rims/tires) and it made a pretty good jump in steering. I have since adjusted to it and I love the steering now. I wouldn't increase my front tire size until I saw reason too, so far I have none. I wonder if your overall rolling resistance is coming from having all 4 corners being 255. I am no expert in such things but with my staggered setup I didn't really notice any real increase. The steering feel was what grabbed my attention.

Also, are you running boosted? if not I definitely don't see any real functional reason to run 255's or even 245's. However wheels and tires are completely subjective from driver to driver, but that's my thinking anyway. FWIW

<hub conversion> Yeah I know... I wasn't doing it for the clearance. I just hate the 5x 100 bolt pattern...or better yet the lack of wheel options.

Like I said its just something I would like to play with, its not something I am likely to do.

I would like to see how your 265's run and feel. I wanted 265's but went with 255's knowing that it wouldn't require any rolling or rubbing issues. So far they work pretty good.

Tire compound can sometimes make more I a difference than just a wide tire. My buddy is running 275 nitto nt01's on a 930+ whp s2000 and he can dead hook third with a full tank of gas, so I think those in a 245 would be near perfect on our cars.

Okay, not to get into a tire and compound debate...but since I will be sure to burn my pilots off in the next 10000 miles. Does anyone here have anything to say about the Nitto NT01's versus the Bridgestone RE11's.

Interested to hear actual experiences.

I am pretty sure a big part of it is the fronts being so wide. Steering feel is certainly heavy. I don't particularly care for it, to be honest.

Yes, I have the innovate blower, so the rears need a bit of meat to hang onto the earth. Wouldn't want to float off into space or anything.

Well for one the Nitto NT01 is an R comp tire. I have heard it shares tire compound with the Toyo RA1. The RE11 is a street tire that can perform fairly well on the track.

On the street do you know or think there would be much of a difference in rear wheel grip between the two.

In the end I may just buy both (no not at the same time) and see for myself. But that will take a couple years, as I am not in the habit of tossing tires that have more than 50% tread left.

My only real experience is in going from my 205/50/15 Kumho XS street tires to Toyo RA1 R comps on my SpecE30. They felt about the same but the R comps had more overall grip and did not squeel as much near the limit. That is kind of what I would expect from the NT01 and the RE11. They will probably both have similar sidewall characteristics while the compound on the NT01 will provide better grip. I am sure the RE11 will beat it in the rain.
