These new tires may last much longer
Will they last longer? Everytime I have replaced tyres it has been because the tread became too worn, not because they got a puncture. Why will an uninflated tyre's tread last longer?
As a former S15 Silvia owner, you can go through the tread on a set of tyres pretty effing quickly... An afternoon isn't difficult.
We already have uninflated tyres, they're called run flats (well they can run uninflated) and have some serious drawbacks, not the least of which are how incredibly hard they are leading to a very harsh ride and that's as a person who revels in a hard riding sports car. A decent sidewall will smooth out a rough road and still maintain a good amount of feedback for the driver. Runflats tend to require excessive and complex suspension setups to protect the precious bot-bots of people who buy automatic SUVs from anything that might distract them from their phones, they use the runflats because they look better on massive rims. A wafty saloon with large tyres will have a much smoother ride with much simpler suspension.
That being said, I don't think run flats last longer or shorter than larger tyres. That has more to do with the material used for the tyre, generally softer compounds have better grip but wear faster whilst harder compounds have less grip but wear slower. Hybrids and EVs are often fitted with hard tyres to minimise rolling resistance, sports and performance cars use softer tyres to maximise grip and feedback.
