225 on a 7" rim
Searched and only got a bunch of bunk results.
Well right now I've got my Kosei K1s which I'm really satisfied with but I feel that the 205s I have on them now are a little narrow. I'm sure someone has run a 225/45/15 on a 7" kosei or something similar, anyone have pics or experiences with them?

I have 225/55-15 toyo proxxes 4 on some 7" enkeis, I was told 7" is the minimum width for 225 tires, but apparently these newbs (pat excluded) think otherwise. I don't have any real good pictures of the tires, but I'll tell you this: its black and wide and looks like a tire.

2 trips to DGRR with my set up on a Mazda far heavier than a Miata, and it handles perfectly.
Who's the 'newb' now!

I should have clarified, I was told through RESEARCH that 7" is the suggested minimum width of wheel to run a 225 width tire. Now as many of you know, you can put a 195 width tire on a 9" rim, and you can even put a 245 width tire on 5.5" rim, basically whatever holds air is supposedly "good to go"
However putting a wider tire on wheel that is narrower than suggested by the tire manufacturers will use all of the sidewall's available flex, thus resulting in the contact patch flexing to get the desired 180 degrees. With a contact patch that isn't flat, you're not getting the full benefit of the wider tire, much like an over inflated tire.
BUT! with only a .5" difference between the suggested width and the 6.5" that you're using, this could probably be solved by lowering your tire pressure by a psi or three. So before I get flamed for my miata.net snobishness, I just wanted to make it clear that I merely voicing my surprise at all the folks with 225 tires on 6.5" wheels, NOT saying that you're all wrong and I'm right, and apologize if my answer came off as so. Pat's wheels do look very nice

I have a friend who turned some very impressive lap times on the 205's...I believe a 1:38 at hallett in an NA 1.6...I'd say thats better than average for a street 1.6 on r-comps...but of course he did it on R1R's.
