Guys, I have the SSEi with the turbine wheels, and they come out of balance all the time even with the best Goodyear RSA'*. My tire place also changes my oil, and they have heard of that happening on some makes and models before, so they just do a rotate and balance every 5k with the oil change, and I have had no more problems. They said that when it goes out of balance, the wheel actually slips on the rim and a new tire is being developed for vehicles that have this problem to eliminate slippage. Hope this helps!!
