Cage should fix most of that twisty loading stuff. Most of it.

Another idea Ron, Jeff and I were kicking around yesterday was this. SM gets a great deal on SM6 tires. They do so by negotiation.

What if IT did sometihng similar for the 4-5 most popular sizes? 245/50/15, 225/45/15, 205/50/15, 225/45/13? Last check the SM6 was about $50 per tire less than the equivalent non SM6 tire.
