Adaptive suspensions with adjustment rates on the order of milliseconds are going mainstream in consumer vehicles. Air suspensions have been common on commercial trucks and some SUVs for some time.
Why are pneumatic tires necessary or helpful on vehicles equipped with such suspensions?
I understand why a wearable tire is necessary: the friction coating on the wheels does need to be replaced. Recent years have seen a proliferation of very low-profile tires for road vehicles, but to my knowledge they are still always pneumatic. Why? The downsides to inflatable tires are that they perform poorly when improperly inflated and are subject to failure, including catastrophic decompression. What are their upsides? For example, do they provide damping responses that can't be replicated with an air or adaptive suspension?
