Hmmm, I thought it was the other way around. Fresh new rubber is more supple (and can flex better on the road to resist wear) while older tires are more rigid and scuff more when in use. Now, I wonder which of us is right?
It's probably a little bit of both. Flexing also creates heat. Harder rubber resists flexing, but also may not give. The compound probably matters. Silica is added to tires for various reasons, including improved flexibility at cold temps, but it's also known to improve treadwear.
Still - softer rubber like on winter tires is notorious for wearing quickly.
