I may even have a spare tube

was figuring this based upon UV cracking the tyres, but thought the tubes (and the inside of the tyre) would doze over time, and gravity too of course. The lack of rotation, causing the 'rubber' to sag over time. I dont know, am just thinking out loud (or in text lol). an example, albeit with an obviously different compound, the tyres on an old MRRC slot car, flatten over time if left unused actually forming a dome shape! (but it is this reason I am suggesting a replacement tube as opposed to a repair kit).
