The process was easy from online experience thru the install process. However, I was disappointed that one the Tire Rack recommended installers didn't have the proper equipment for my Audi A8L (Pep Boys District Height MD.) Good thing I called before I had them dropped shipped. I had the same problem before when I was dealing with my Jaguar S-Type with the Exxon in Largo MD. Tire Rack should update their recommendations.
