How do you drive the omi in winter?

With the current smooth road conditions I fight with my thick ship on every small incline (mountainy area) > rotating or locking (TC) wheels etc. although the brand winter tires (test winners at the time) are still quite new. Sure – with rear drive you have something to look for, but it is very embarrassing if you play traffic jam drivers. So the question – how can you improve the starting behavior of the omi? Cement bags in the trunk?
