I used a product called ride-on in my last car a Mitsubishi Outlander phev
It’s safe for TPMS, it balances the tire and provides a coating inside the tires that seals punctures.
No, it doesn’t work on sidewalls or major tears, only punctures in the road contact area.
I bought some for my XC40 recharge but haven’t installed it as yet.
It’s not like the latex milky liquid that comes in the emergency repair kit, it’s very thick an stays on the inside tread area.
I also carry a plug kit just in case.
Check out the online reviews of Ride-on.
Most major tire manufacturers are offering a similar product, Michelin, Bridgestone, Pirelli etc
These are not run flat tires, they are considered self sealing tires.
