Here is another take on puncture proofing your tyres. It's called "Tire Balls" and I have not tried them, just read about them:-

"It works like this - balls (air-cells) replace the vulnerable inner tube or tube-less inflation system. The system is designed to retrofit to conventional tires and wheels and is lighter and more durable than foam inserts. In a motorcycle the best number of cells equates to somewhere between 28-36 Tire Ball cells with the effective tire pressure varied for the prevailing conditions by adding or removing Tire Ball cells or by adjusting the air pressure in the individual cells. Cell pressures can be adjusted from 10 - 12 psi for woods riding, 3-5 psi for Trials riding, and up to 16 psi for high-speed desert conditions and the good news is that as well as being lighter than most tubes, you can run much lower pressures for better traction, without worrying about flat tyres.

Each individual Tire Ball cell is made from materials that are claimed to be ten times more puncture resistant than conventional heavy-duty neoprene tubes. Punctures are still possible, but very rare. Instead of losing all the air in your tire, only one cell goes flat, allowing you to finish the ride without needing to lose countless places in a race, or spend 20 minutes fixing a flat in the middle of the woods when you’d rather be having fun."

It sounds like a load of balls to me and if anyone has tried them out perhaps you could share your experience of them.
