The Pirelli SmarTUBE Patch Kit is built specifically for TPU tubes, a tube style that most standard patch kits aren't designed to handle. Each kit includes five large patches, five small patches, glue, and alcohol cleaning tissues, giving us everything needed to seal a flat and get back on the road without swapping in a spare. It's made for Pirelli's SmarTUBE line, though it isn't compatible with the P Zero SmarTUBE RS. What Our Gearhead(R) Experts Are Saying:"I flatted a TPU tube forty miles from the car and had it patched and holding air in under five minutes."
