Does anyone have a list of the tire sizes that the Kumho's will come in?

I am trying to see if they will make a 265/35/18.

I believe they will have a 245/40/18 tire size.

Do you think they will last one season -- especially with dual driver's -- only SCCA, NE DIV II, and a few other events. So, maybe a total of 15 events with 2 drivers.

Will I be better off getting Kumho 700's instead?
