After Running trails like Chinaman's and SpringCreek last year I'd say 32-33s and lockers should be the required minimum equipment .I'm sure you can get by with a locked rear open or limited front ,but lockers F/R would be optimal .
I'm not saying this to be a debbie downer , But everyone says trails like SpringCreek and Chinaman's are easily done in a bone stock Jeep with the right driver and taking the easy lines , well last year going to SpringCreek I witnessed every unlocked rig struggle and bash their way up Spring Creek on 33-35s that had no lockers while taking the easiest lines you can immagine for the trail , and the reason for it was a simple sprinkle of rain while on the trail , and the same happened to the Rubicon in our group when we ran Chinaman's and it rained , which he was on 32s with high clearance bumpers and rocker guards , which he did well ,but without the lockers it would have been spinnning tires and bash city . There is a huge difference on these trails from a dry season where it's a dust bowl to when there is any percipitation leaving the trail a little wet ...LOL...I think T2G if he recalls the SpringCreek run last Summer with the same clarity I do that it was not pretty for the unlocked rigs even the ones on 35s ...it took the Toyota truck an hour to reack the rock garden and atleast an hour to get up the trail from there and is was a bash fest leaving that truck not looking like it did b4 the run .
