After buying a set of 20 inch rims and tires from this company I have had nothing but regrets. First, t I received one of the tires with no air in it and I noticed a slow week that would require me to ad more air within a day or 2. After further inspection I found the leak was due to tsportline not fully screwing in the valve stem. Obviously quality control is not their number one priority. Glad I didn't get stranded somewhere with a flat tire. Second, and the most frustrating is that the tires or perhaps the rims make a ungoddly harmonic vibration sound around 56-60 mph. I took my Y to the Tesla service center near me and both the service advisor and Mechanic confirmed that their was definitely an odd noise around 60 mph and rebalanced the rims and inspected the tires but nothing was noticeable enough to say what the problem was. So of course my next course of action is to contact tsportline, so with the tesla invoice in hand noting the problem with my concern I called TSportline. Wow!! If Customer service is what you want after buy a set of tires and rims then look else where. I talked with Elie Rothstein directly who is the president of the company, he was very persistent about it being just in my head and that I maybe should just avoid driving 60 mph. So after about 10-15 minutes of back and forth and going nowhere with this guy I finally had to say I just wanted to return the rims and tires as I can not use them, something just isn't right. HE HUNG UP ON ME!! that's right, HE HUNG UP ON ME! After reading other posts I find a lot of owners complaining about how rude and obnoxious this guy can be but, WOW! I don't know how he can run a business being so evasive and immature. So my advice to anyone looking for after market tires and rims and want some reasonable customer service after your purchase , look else where TSportline is not for you..
