Needing help/thoughts...
Looking at getting winters for the S3 8l and I've seen 2 x 225/45/18 and 2 x 225/40/18
So I was wondering if this would be ok to run with the haldex on the S3.
Would these calculations be correct....
225/40 = 225mm width and side wall 40% of this so 22.5 x4 = 90mm ie 9cm for side wall (4.5 top 4.5 bottom)
225/45 = 225 width and side wall 45% of this so 90mm + 11.25mm so 101.25mm ie 10.12cm
So 1cm different? (.5cm top and .5 bottom
