I am so excited to hear you are growing in God, in the ways He speaks and also being confirmed! Praise Him!
You are right to search scriptures first when learning to interpret. One of the ways God speaks is through wordpuns. A tire is a TREAD.
Joshua 1:3 Every place that the sole of your foot shall tread upon, that have I given unto you, as I said unto Moses.
Luke 10:19 Behold, I give unto you power to tread on serpents and scorpions, and over all the power of the enemy: and nothing shall by any means hurt you.
A spare tire is something that accompanies you and backs you up when your faith becomes deflated. Angels back you up!
