BOBBO,
Your link is to a FARM TIRE comparison page. I am sure there are some similarities, but I would rather compare my bike tires to a vehicle that will travel more than 12 mph.
ALSO, the D407 tire that I am running on the rear of my bike is manufactured with their new triple compound, that should remove the issues of wear on the center that your link says is a problem with the bias ply tires.

True, but it showed the different construction of radial vs. bias, and reasons for performance differences in general. That's why I posted it as additional information, not a buyers guide or a pro/con opinion.
The new triple and dual compound tires do help with tire wear and longevity, but it is mostly to compensate for riding styles, rather than deformation due to low sidewall flex. The majority of riding for most motorcycles is straight up, as in highway riding. The harder center compound wears slower during straight up riding, and the softer compounds help traction in cornering. If you ride Deal's Gap a lot, you will wear the sides off well before the center!
