Tires are complicated

Excellent argument, Clark,

But I notice at the MAXXIS site that the tread rubber designed for racing is NOT the hardest--

>>>>
57a Silica based compound created specifically for our Road Racing line.
• Enhanced grip
• Low rolling resistance
>>>>

And note this statement on casing construction--

>>>>
120 TPI Casing used in our Road Racing line, Cross Country eXCeption series, and BMXception series.
• Lightweight
• Smaller gauge cords
• Highly supple casing
>>>>

Don't I see a consistent pattern of greater flexibility in the racing materials?

" Sticky Soft compound on side knobs and ARAMID RACING 3D on the central ones. That's the best compromise you can get from both the compounds: cornering grip and braking performances keeping low the rolling resistance. Soft side knobs guarantee a strong bite in turns and excellent grip in all situations whilst the central (harder) compounds with aramidic particels makes for lower rolling resistance reducing wear and tear to acceptable levels. It's the ideal solution for racing tyres"



Note on this page that all the low rolling resistance tires have a hard compound
