I bought a set for Sept./October installation. Early reports like the Pirellis for noise reduction and efficiency. Those reports are simply initial reactions. There is really not enough data to know (people with 10K + miles on them). For other variables (wear, handling, winter performance, etc.), there is not any information. Perhaps, one can make assumptions based the non-elect version which has been around for a while. What I do know now is that they are going in and out of availability in limited sizes. If you see some and really want them, you might want to consider buying them at the present price.
