Pilot Sport Cup Fitment Question
So, I am considering track tires for my M3. A lot of people here mentioned the Cups, so I did a little research.
The Concept M3 came with 19" CSL + Cups:
However, the OE 19s come with:
So, using the tire diameter calculator, I computed the difference between OE and Cups:
So, my question is: is such a big difference in diameter still going to be ok on the M3? Tire rack recommends deviating within 3% of the OE diameter.
Moreover, for 19" wheels, Cups only come in:
Thus, the 235 front and 265 rear seem to be the only possible choices for Cups to be used on the M3. There is a big difference in diameter on possible 18" wheels+tires also.
