In 12V days there was a service pack available with extra rubber tires if your
original ones (from the 12V motor) perished or were otherwise damaged.
This service pack is now highly prized as it's been out of prod for 20ish
years.
I am 2000 miles away from my train stuff but I could swear that:
- there is a (much smaller, black o-ring like) tire on the plastic wheel of a
9V motor, one per wheel
- there is no service pack available for this part at all.
Hence I tend to think anything that damages these tires is bad. That includes
overheating and oil, which will damage the rubber if it gets on it, the rubber
tends to swell up and it works itself off the wheel.
