Yes, it's the glue that they use on the plug that will cause havoc on the foam if not careful. Many years ago on our 17 MS found out the hard way. Walmart was the only store open on a Sunday. The tech got a little happy with the glue on the plug or maybe he was trying to glue the foam patch back in. Well, over a few months, I would need to re balance on the vehicle due to shaking. Later found out that the foam became a glob inside the tire and had to have the tire replaced. You still can plug with foam for I have done that many times on our OEM tires with our 18 MX road tripping.
Been eyeing these tires for a while. Needing a set on our 18 Model 3. Still comparing, but that's a crazy price. Confirmed with Discount Tire they will work on the 19x8.5" rims. Just a bit wider. I'm sure not range friendly.
