I won't disagree with that. And I'd love to get a grip. A better grip than the average BFG will provide. That's the problem. If you ever want to push the limits of your E body, you have to step up to 18" tires with the corresponding cost of new rims, or settle for hockey pucks. There is no middle ground at all.
It does pose an interesting question in my mind if a 225x15 V rated, 200tw, UHP tire could grip better than a 295x15, T rated, 360tw, all season tire.
