I dont know what the standard over all diameter is supposed to be but in the 17" range, 215/45/17's (which i think is accepted as the norm - except 215/40/17's are easier to get hold of) have dimeters of 625mm. And 225/35/18's have a diam of 615mm. And 215/40/17's have 604mm.
The 215/40/18@s give 630mm, which is closer, but this will give a nominally slower speedo reading, and supposedly its better to have an over reading one!!!
I was quite happy to run 215/40/17's and found no problem.
So theoretically by running 225/40/35/18's i'm even closer to the originals.
Anyhow i've found no prob at all and i'm well chuffed with my new OZ WRC1's !!
Cheers

Was only wondering?,when i changed my STI7-225/45/17s to 18s i had to change to 225/40/18s to keep the diameter the same,its all really confusing!!! I know these would fit on mine but would they affect the speedo?

I presume 225/45/17's are standard on an STi7 ?
The diameter of 225/45/17 = 634mm
And 225/40/18 = 637mm
Which is virtually perfect (very slighly slow)
I was happy converting from 215/40/17's to 225/35/18. (1.7% difference)
I'm totally lost, as to what car came with what tyre as standard.
Mines a MY96 import, so it will have needed a speedo conversion.
Did the "convertors" take into account the tyre size ???
I dunno. I'm only asuming they did and it is meant to run on 215/45/17's. So by running these new 225/35/18's i'm very close.
If you changed from your originals to these 225/35/18's your speedo would be 3.1% to fast. Ie Reading 70mph is actually 67.83mph.
Assuming your speedo is already deadly accurate - which ists not of course.
