Simply Auto TRK01 8 Piece Tyre Repair KitA screw or a nail in the tread does not have to end the journey. Simply Auto 8 Piece Tyre Repair Kit carries everything needed to plug a small puncture in a tubeless tyre and get moving again: a T-handle rasp tool, a T-handle plug tool, five repair strings and a 12ml tube of rubber cement.The rasp roughens and cleans the inside of the hole so the plug has something to key into. The plug tool carries a cemented string into the puncture, pulling the tool straight back out leaving the string in place and ultimately sealing the hole from the inside as well as the outside.Both tools use a T-handle for easier repairs, because pushing a plug through a tyre carcass takes real force and a straight handle gives you nowhere to put it.Five plug strings means the kit covers up to five repairs rather than being a single-use item. For tubeless car and truck tyres, with the full sequence printed on the pack.Note: This is an emergency repair to get you off the roadside and to a garage. A permanent tyre repair means removing the tyre from the wheel, inspecting the inside for damage that is not visible from the outside, and confirming the puncture sits within the area a tyre can legally be repaired in. Have any plugged tyre checked professionally as soon as you can, and replace if required.
