;Dr; Apostle-- unless it rains, no one will be getting stuck on this trip! ;Dr;
I use a less-than-spectacular BFG all terrain tire, 265s, slightly larger than stock but not special... and they work just fine on the Chivo Falls trails. The more difficult obstacles have bypasses.
Clearance is a little more important than tires, in my opinion. The same damn rock has **clonked** my oil pan twice now!
Be sure to let us know if we can help arrange a place to stay on Friday night.
