The General G-Max AS-03 is a High speed, high performance tire. This tire is far superior to the run-flat tires that come stock on the Mini Cooper. The tire is very responsive at high speeds and resist rolling over in the turns. This is a soft rubber tire providing very good traction in snow and on ice. The Mini is to low to go in deep snow, has nothing to do with the rubber. We have had a lot of snow and Ice in Minnesota this year and I drove a brand new Mini Clubman this week and my Mini S gets better traction with the G-Max that the brand new run-flat tires that come on the Clubman. Great grip and performance on the dry road, Tire sheds water nicely in the rain and i have had no hydroplaning issues Very good traction on snow and ice. I recommend checking the tire pressure regularly. I have had to add a couple LBS twice to keep tire pressure constant. This is most likely the result of my driving style than a tire issue.
