I have a Cayenne s titanium and put on winter wheels which are 18" with 45 offset. I am having trouble balancing tires as they vibrate at speeds over 65 most of the time. Some times they do not vibrate so the tire company says maybe the spacing is not correct with the suspension.
Has anyone had experience with this?

 

I got this same problem... it starts vibrate around 65-70mph..

I recon that my tires are bad.. so i´m waiting on new ones, and rims as well..
