Tellico trails 4,5,and 6 along with parts of 2, 8, 11 (leads to the base of Guardrail) are all doable for any 90 with 2" lift and MT's. There's a "go around" at the base of the Guardrail that will allow you to avoid the carnage on the way up to Helicopter Pad.
Been going twice a year for a weekend in April and in August since 2000 and with the exception of one mishap in my Disco (sideview mirror caught a root and ripped off and did some panel damage on the way off), I've never gotten the first scratch. Just be careful and don't let anyone talk you into going up the Rock Garden, Schoolbus, or Peckerwood unless you like going to the body shop.
Anything is possible, with the right tools...
