Claim rejected because I put my safety first

I could not drive with that tyre, I put in the spare and changed when I got home because I have 2 spares tyres that I kept when I bought 2 new tyres in August.

1. Was I supposed to travel with a spare tyre that goes at 80km/hr until you resolve the claim? 2. How am I supposed to get an invoice from some changed the tyre for me who is not a formal trader? 3. My safety comes first, I had a spare tyre that is still roadworthy and used it when my tyre. 4. Point me to the part of the contract that states how I produce an invoice for exchange of tyre and why I exchanged the tyre
