I have no idea of the overall impact (pardon the pun) of this, compared to increased safety of (louder) tyre performance, but probably worth considering. > Managing air pressure in tires can be problematic, airless tires are a welcome innovation. True, but modern cars have inbuilt pressure sensors, and these can be retro-fitted relatively cheaply.
