Never ever get rid of it! I left mine at home and went driving round one night, managed to get about 60miles from home and i got a flat, problem was didnt realise stright away as it was a back tyre and didnt effect my handling, the tyre was then f**ked so cudnt use foam or anything like that, the next part of my adventure involved getting a new tyre, but at 11pm not many places are open and the other problem being stuck in the middle of nowere! ALMOST sleept in my car until a long phone call to my dad, ive learned my lesson this time, dont ever get rid of it!
