All a matter of perspective with these things... Motorcycle tires, just like performance car tires, are made from a rubber compound that yields better performance in several characteristics (speed rating, grip, wet/inclement weather, handling, etc.). That's why you can buy all-season, M/S, A/T, etc rated tires. Those designations don't just come from tread design. They have a lot to do with material ductility and other mechanical properties of the product at certain temperatures and in certain conditions. Motorcycle tires are not necessarily designed for the longevity you'd expect from a car touring tire. They are designed for peak handling, grip, even wear, wet weather performance, and on the list goes. Saying that no engineer(s) has designed a tire for this motorcycle is ludicrous. They just haven't designed a tire that performs as we all expect and has a 30k mile lifespan. It would be very difficult to find the best of both worlds, here. If you are only concerned about longevity of the tire, then run a car tire. If you prefer to have the performance from a motorcycle-specific tire, then run one of those. Perception dictates reality. Live and let live, gentlemen.
Also, I am a Resins engineer and work in manufacturing and design. People need to realize that products are designed for more than just 'whatever the company wants.' There are guidelines that have to be followed in the manufacturing world that the consumer never sees. Open your eyes. Engineers can't just work for 'the MAN'; they also have to design for safety, performance, manufacturability, etc. Making sweeping statements about how none of them are competent is a gross misrepresentation of a group of technical folks and is an insult to those who work to improve products for the rest of us.
