I called America's Tire and will be getting 245/75R-16E Michelin XPS Ribs
(3042lbs @80psi) and 16" MB Type 72 wheels (rated for 80psi) all installed w/certificates for $1363 (after $100 rebate) tomorrow. I'll have 1 yr to pay w/o interest.
The 245/75R-16's are 30. 6" dia vs. 28. 3" for my current 15 ST's. I should have approx 1. 5" of clearance between them after the install.
Thanks to all for the replies and commments.

Smart move on the XPS Rib's & wheels, congratulations. That sounds like a real good price. Are you getting 5 XPS Ribs and wheels? Be sure you get the heavy duty valve stems because the medium duty can't take 80 psi.
