Autox'd on them today and realized you can NOT do the typical autocross technique by running oversized tires on otherwise-small wheels. My DD has 285/30/18s on a front 18x9 wheel (295/30/18 on the 10.5" rear), and the car was very unstable in the front and understeered like a mother. I could not dial it in with tire pressure adjustments, the tire was just rolling over too much for the slightly-small wheel. These are not my normal autox wheel/tire combo, but thought I'd try them today for a no-points event rather than change to my 285/30/18 x 4 Kumho V710s. I won't be doing that again.
