As soul mentioned I'd either thread repair it. If not i'd use slime tire sealant. Jack the car up, remove the nail, but the but the holed area to the bottom. Remove the valve, then add the slime. Wait till the slime dribbles out of the hole hence being on the bottom. Spin the tyre by hand for 10 to 20 revolutions. Install the valve and then inflate to pressure. Go for a short drive and then check the pressure again. Top up the air if needed. Check again in a mile or too to see if it holds air. Used to do this to motorbike tyres regularly. Never had a problem.
Use slime as you can wash the slime out, the spray cans of foam are a bugger to clean out.
Or see how much a set of tyres is, BMW don't have to fit them.
How much mm are left on the tyres?
