3 Bridgestone Driveguard 215/45RF17 run flat tires low miles high tread

For sale are 3 bridgestone driveguard tires. I had a tire blowout and switched to conventional (non run-flat) tires, so now I have these. They have low miles (less than 7k) and high tread (I don’t know how to measure exactly but it looks like 8-10 / 32 ). Two of them have a late 2017 date code, one is a late 2018. I only drive about 3k miles / year so the mileage on these is low.
