I’ve had my 2020 Explorer since September of 2019 recently had a vibration issue thinking the tires were out of balance took it in, I was there for almost 5 hours while they were trying to figure out why they wouldn’t balance. They finally got it and I went out to talk with the mechanic said he removed the foam in the 2 tires. I contacted Pirelli and told them what they did and said they should never have removed the foam. Now I’m wondering if it is safe to drive like that. I only had 18,300 miles on it although I’ve had it 4 years I have an extended warranty and I talked with the service manager as well. The only other thing I can think of doing is contacting the Ford Corporate Office to see if anything can be done as of now there is no recall on these tires
