That's car tire prices. I won't spend that on bike tires unless I was a bonafide racer. The material cost, tooling cost, and perhaps even labor cost, are vastly less than for car tires. The prices are high because that's what the market will bear, and bike prices are way up, so it's not surprising that the top tire brands raised their prices. But is there in an inprovement in the technology? I don't think so. The key is if there are alternatives, that aren't functioning like a cartel to keep prices high. Elasticity in supply.
