Temps, wheel size, tire size, tire age, tire type, would be helpful to know if its the X5's fault you slid around or not. Also, cold tires will always be less grippy until warmed up a bit. I always go extremely easy for the first few mins of driving as I know even if my tires are good they still need to warm up
