I spoke with Mr. Kelsey yesterday about the H's and he said, "never say never, but don't hold your breath."
Each time a new tire is brought out, it represents a full year of design, development, testing, and trials before they see the light of day. Therefore, you must put forth a great deal of resources (time and $$$$) to make this happen, and you have to know that there is going to be numbers of tires sold to justify the resources placed into that item.
This is one reason why the G70 took so long to come out! The tire has a limited number of vehicles wearing this as a OEM application, the tire molds had to be built from scratch, etc. BUT...... that tire is here now, the price has been reduced, and I need to help you guys get them on your cars!!!!!!!!!!!
