These cars can handle up to a certain % increase or decrease in tire OD to correct the speedo, at least seeing what is said on SVTP that is. You don't really need a tune, but just a programmer that can adjust the values in the ECU via the handheld.

I personally try to stick as close to the OE tire OD as I can.

But we need to know tire widths and types of tire you are wanting to run.
