It puts roughly \u003cstrong\u003e15 mm of puncture protection under the tread and 2 mm along the sidewalls\u003c\/strong\u003e, so glass, thorns, nails and sharp rocks stop before they reach the tube. It also lets you run lower pressure for more grip and a smoother ride, and if you do flat, the insert supports the tire so you can limp home instead of walking.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSold per tire.\u003c\/strong\u003e Order two for a full bike.
