You could try the following:
Michelin 19 inch Ultra Heavy Duty Tube (Motocross)
Featuring a 4mm wall thickness, the Michelin Ultra Heavy-Duty tube is made specifically for those who push their tires to the limit in the roughest of conditions.
Reinforced tubes for off-road applications
4mm wall thickness
Provides outstanding protection against punctures and pinch flats
TR4 stem type
Michelin make heavy duty tubes, I have used them in various vintage cars and have never had a flat, the above are for motorcycles as I'm not sure they make a car one narrow enough.
