E36 M3 Track Day Tyres

[sweetm3 180]

Hi Guys

I haven't found any 17 X 8.5 track day rims yet, but I have brought four 8.0 inch rims in the mean time.

So the next question which tyre size

Toyo R888 235 X 45 X 17 or Toyo R888 235 X 40 X 17

The 235 X 45 are 2.41% larger than standard : @ 100km/h speedo reads 97.5

The 235 X 40 are 1.26% smaller than standard @ 100km/h speedo reads 101

Cost wise the 235 X 45 are about $ 200 cheaper

Hell does it matter :-)

I had this very choice last month when I was purchasing mine and I went with the 45's. No real reasoning but what i do know is that either will be fantastic as it's a brilliant tire
