Folks, we all are running some wide slabs of rubber and Porsche is not very gentle when it comes to tire wear. So balancing and aligning is paramount for a good handling car ( including tire pressure). After 2,000 miles it was time to get my car checked out again.. You know it start off with this tiny little vibration that happens between X-speed and Y speed and disappear at about 100 miles per hour or more. :-)
So have your tire guy remove ALL leads / weights and clean that rim inside and outside and start from scratch with the balancing. It will work great!!
