You put 32" on a P1K and actually ride it (vs. trailer queen) all the stock parts will answer the questions for you. After about $6k in upgrades after you spend $$ on the tires, you will have addressed most of it, then realized you probably should have stuck with 28x10x14. Vanity has a high cost, but the highest cost is crippling an otherwise great handling machine. Not sure the regular 1.5" forward A arms will clear true 32" tires either, just 30's is all I have seen over past 6+ years.
Tires & wheels 30" +
Forward A arms
HD tie rods
RB3 Steering rack
Then likely spacers unless running 4+3 wheel offset.
Rhino 3.0 axles
You might be able to do it right for $6k
