I think I pay $12 or so for mount and balance at Walmart, but that includes 5K rotation and flat repair at any Walmart. The service guys seem as good as anywhere and some have gone above and beyond to help out.
I have the RC too and love it and it, like me is cheap, win win. Mine came with the lights, which I wired into the rear power point so I get 45 minute camp light availability. Mine also came with the spare tire license plate relo. I don't like spare tire mounted ones so I modded it to work on...
For the last several sets of tire I bought I have used Walmart.com. You get to browse every brand of tire, sometimes directly from Walmart, sometimes third party. Sometimes tires will ship to your local Walmart sometimes to your home. Regardless I have Walmart mount and balance, I have never...
There should be a fuse to pull to disable parking brake or unhook wires at actuators at calipers . This would disable only parking brake and not service brakes. But might send a code to the Bronco causing a freak out.
I had brakes set (never new if service or parking) inexplicably off road...
I used some hardware store bracket to mount my towed battery charger to this point.
As far as the winch I leave the positive disconnected at the battery and have a wingnut on the appropriate stud to make my connection
I've spent 55 years four wheeling, mostly with no locker and did great. Then I got a Rubicon with both and got cocky and stuck some. The rear was real nice to have, the front didn't add much marginal performance. Now the Bronco. With the ifs at least one is essential, these things love to go...
Your dilemma: If you get the 285s you'll always think you need the 315s for the look or clearance, If you get the 315s you'll always think your 3.73s aren't enough, you'd be wrong in both cases, but you know, perception is reality
I had the brakes lock up in an off road situation a few years back, after about 10 minutes of various tries they released, hopefully yours will too. As far as the ramps, why 4? Anyway, try 4L it'll help climb that hill and disengage traction control which may be the problem.
I've been blissfully running LREs on all my 4x4s for years. It may not matter in your use case but It's been many years (I actually can't remember one) since I've had a puncture running rocks and sticks and cacti all over CO, UT AZ et al. I run 32 psi on my Bronco with 265s.
