Since I am running in Street Tire class like Redlinetoy, I will be running on my stock Yoko A046 till they are done for. Then I planned on swithing to the Azenis RT-615.

What I really want to know is what makes the Azenis a better AutoX tire then the A046. Below are the specs

Tire Price Size UTQG Tread Depth
A046 $244 235/45 17 160 A A 9/32
RT-615 $170 245/45 17 200 A A 8/32

The A406 is more expensive and a faster tread wear. Seems like the stickier tires have a lower treadwear. Why would a tire that wears faster and has the same traction/temperature cost that much more then the #1 rated tire for AutoX. Thoughts?
