abAs long as you're upgrading the rims & tires, consider adding Centramatics. They will dynamically balance your tire/rim/brakes/hub assembly. Absent proper balance, vibration can do all sorts of nasty stuff, such as loosen rivets, open drawers & cupboards.
Last summer I went whole hog - replaced and upgraded my axles, plus Sendel 16" rims and Michelin LTX225/75R16(E) tires (including the spare) & Centramatics. Have put on about 15,000 miles since - rides smoothly and tows like a dream.
