wheel radius measures
I've had a few minutes to run a ruler spirit level and tape measure over my green cars wheels front to rear, and I was pleasently surprised to discover that the front was 625mm and the rears was also 625 ..maybe 624 depending on which way my tongue was hanging out or according to my tape 24.5"..[tyres all cold] - method - ruler spirit across top of tyre horizontal then measured perpendicular thru centre line of tyre/rim to the concrete floor below .. that = 625mm
So then just now checking my earlier posts for 235/40x18 the radius was 12.7" and diameter 25.4" [~ 645mm] so why the difference ..call it 20mm or roughly 0.75inches...
i am pleased that they were at least same front to back...
