I was thinking it as it is available in the 225 size as well. IMO the Fiesta is just too heavy for them especially when it gets hot. The R1R seems to need lighter cars then ours are.

Is a R-S3 in 225 45 16 too much to ask for??

Apparently so, I have been debating experimenting with a 205 size tire but I had good results/feel with the 225. If I get to spring Nats and I get my ass handed to me on all cars with 205s....I will change.
Still don't think the R1R is going to be the tire for our cars.

I am running 215/45/17 rs3 and I had some rubbing when doing medium to hard turns. I installed some 2 coil boosters as a temporary fix, and I get no rubbing at all. So I am sure a 225/45/16 tire will be just fine, maybe a little rub on the stock wheels when doing full lock to lock.
Edit: on a stock offset, I know a 16" rim is not stock. Morning typo's....

There is no Kook in the 225/45/16.
The 225/45/16 ZII is just fine, ran that size all last year.

I'll be fairly surprised if the R1R works on this car in anything above 60F. I've been running the Z2 star spec on the Spyder since nats and I'm super impressed with it where I very much disliked the regular Z2 so I plan to try that tire first in a couple weeks.

No the 45 profile vs 50 is a 1" OD difference, so a .5" less clearance. I'd expect that to rub badly based on reports of how 225/45/17 fit though I haven't tested either personally.

Des, do you know the required offset for the 235/40/17 Z2 SS on a 17x7? Ed told me it had to be stockish and 42mm definitely would not work but I was curious how much room there might be to the fender.
Is that with stock rims? I thought I had read that they don't rub in that size.
Des, did you guys test the 215/45R17 RS3 v2?

Also, what size did you like best? I can't decide between 225/45/16 and 235/40/17.
I believe the 215/45/16 will be the best size, but I will run 205s before 225s. The STC and STS cars proved the 195 R1Rs (yes special compound along with many other factors) to be faster than larger sizes. Brian Peters also did not appear to gain much from the 25mm increase from STR to STU on his 350Z. Of course I truly dislike the feel of pinched tires so my bias shows when discussing this.

Yes we tested the RS3 in 215 but didn't like the feel. I don't remember encountering any rubbing but we only ran one event. Tom, I think you'll have plenty of data to compare the 225 and the 235 but I am going with the 235 as I did on my FRS. In this case it's more for the extra height over the 225 than for the width. Most folks have gone with the 225 because wheels are so much easier to find. There's almost no difference in tread width just a bit on height

No it was with the Sparco Gara wheels I think the offset is +42

From ST Civic experience, unless there was a compound change on the R1R that deals (a lot) better with heat then I doubt that the R1R in ANY size will be the right answer.
My initial "shot" was a set of 205/40R16 RS3v2s on the Asseto Garas. Not thinking it is the ultimate setup by any means, but something to get some seat time in the car before 23144 new options come out in the next 90 days
