Tire technology can certainly advance, the main issue would surely be the cost. Dollars can almost always solve any problem.
By the way, in passenger tire car design, the tread belts are the most defining tire performance component. Put them slightly off center or worse, with a center line that wanders and the tire will be crap. We spent a lot of engineering time and money making sure that they were cut straight and installed straight. If not you got lateral force variations that wreaked havoc to the tire and what ever you installed it on.

His car ran consistently throughout his run, turning low laps times from start to finish. Besides the belts being a bit thin they were not very straight and tended to wander a bit over the tyre.

You will never see a Corvette using the same compound rubber that you would find on an Accord. And, for the tires that are on the market, there is more concentration on the tread part of the tire than the whole tire (side wall as well as tread area).

I have built tires and it requires a skilled worker to do that. Developing a tire is intensive and working with the car manufacturers is a pain. Believe it or not, the absolute highest quality tire you will own (other than exotics) will come on the new car. Any replacement is built to looser specs than the tire that comes on the car from the factory. It may not be the ultimate performer but it will be the smoothest. Some equipment is actually specified to build OEM tires only.

A passenger tire is built up on a drum and all components are in place before it ever goes into a mold. No part of a passenger car tire is ever poured just to let you know. I believe that the R/C rubber tire is injection molded and therefore also not poured.
Just a little education.
