I agree, if any flowing occurred, tires would not last 50000 km or more than a few months.
I have a bike dyno and if I leave a bike tied tightly (with race slicks) to the frame over night , the next day the tire does have a flat spot. This takes just a few minutes to work out with no permanent damage.
Tires do contain oil which may be adding to the question on what happens.

Either way, you may have sticky short life tires that may flat spot or long lasting car tire that last for years.
