stick with the stock all season tires, no weight in the back. i found if you shift in a high rpm in first two second the tires will break loose around corners. you'll slide real well this way. also you can do the drifting way from downshifting from third or ect to a lower gear kicks the back out around corners. but its better to do it out when there water or snow to save tires cuz 19s ain't cheap!
