Tyre repair kit or tyre plugging kit (same thing) & pliers.
Sometimes a jack and tyre iron or socket set will be needed if you have to remove the tyre in order to plug it, but those tools should always be on board your vehicle.
In most cases you won’t need to take the tyre off the vehicle unless the hole is really hard to get to.
Half the battle when doing a tire puncture repair is finding the hole/leak which can sometimes be challenging as the tyres may be covered in sand, dirt or mud.
Once found, establish wherever it is easy to fix while still on the vehicle or if it’s best to take the tyre off and work on the ground.
Try your best to plug the leaking tyre while on the vehicle, it will save loads of time and in most cases is much easier as the wheel won’t move around, as a fair bit of force is required to pull the foreign object out, cleaning the hole and plugging it.
