I have the sports on my 98 e 430, and do not drive in snow. Without the A/S you will also not be able to get around in snow. I v tried just moving my car once in snow and would not take it on the road in those conditions. So it depends on the weather you use your car in. Other than that they are very smooth and quiet much more so than the Goodyear F1 s that were orig on..
