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.
This all sounds like good advice, @GPPBronco has 'been there, done that'. Just a note to GPP: I like the non Sas BD alum wheels best of all Bronco wheels, the 285s look great but so would 255/80s.
I have 265/70x17 Falken Rubritek on my BB and like them, but they are under 32", so next time...
Under the category of I Ran Out Of Mods for My Bronco: Hook Road MOLLE Vent Cover. I can't think of anything to strap to it and I dont drink beverages requiring an opener, so just for the cool factor.
Question, maybe for @Ducati1098 , I've always felt if it didn't leave drops or puddle it was no big deal. But apparently Ford considers any leakage warrantable? My first car was 1955 Jeep and if it wasn't leaking it was empty.
Au Contrera sp?? Actually, you need a higher skill level to get there with less lift and a smaller tire, so good on you! Imagine a rig with 12 foot tires, it could go anywhere with no skill at all. You wiull become a steely eyed four wheel driver with those 33's.
Oh, and I sense another...
