Ok I wasn't doubting you, it sounds like the same thing advan used to do with there race tires they were 10mm wider than they said they were.
Example: There 255's measured to be 265's

I felt at last track day that I should have more stretch in my tires to get a better usage of my tires.
I guess R Tires works better on wider rims (and of course lower pressure) compared with street tires. I got alot of stess on the outside of the tires in tight corners (to mutch flex).

Ok what tires did you switch from before you got the R888's
I drove a car this past year with the R888's and I noticed they got real greasy after alot of runs. Have you noticed this problem?

Stuttgart read my previous message!
The right rim width will provide a noticeable increase in performance. The problem is that setting up the coilovers for different rims\tires is very hard!

Oh sorry man I didn't see that, I don't have too many machines available to use for personal use. I guess they don't trust us with the expensive stuff.

Yeah if I push my car really hard for many laps in a row then they can get the feeling of slippery/greasy. My solution is to lower the pressure or back off and do a cool down lap.
My theory is to go more stretch and low pressure for not letting them overheat (get greasy) and stopp from flexing in some situations.

But they are really pricey here and the good thing with R888 is that they are capable of running on streets (not so mutch for carring with me a set of track wheels in my car and change before and after)
Perhaps they get better with correct rim wide? im going to try more camber in front and a little toe out as well.

Yes they'll perform better with the right rim width. You will notice the same problem though, only a bit later.
Aren't a048 road legal for you? check camskill.co.uk again, r888 and a048 have got similar prices.
I also found the federal rsr595 for 200€ a piece on another site.
I Would stick with a 235\40 though, we're still running na cars!

I was running stock rims with Michelin PS2 so its not really comparebly, I purchased new rims with R888 last winter.

Personally I don't run anything less than 30 psi, I notice no flex with the Azenis but I have noticed tire clupping this year that I'm not happy with since it gives you uneven tread wear.
My theory on driving is I drive to the edge and if something on the car can't keep up I get something else to help.

Also I forgot to add I run a little bit of camber for the track also when I setup my suspension.
I'm interested to see your theory more in depth even though we both seem to have different driving styles.
