i ran d30 stock non dis, with 33 to 37s and has lasted with me. typical bi yearly swap of wheel bearings is all. took out couple axle joints with 35s and ax 15, but 37s and auto no issues. is it ideal no. can you do it, yes. wheeling should be more about technical driving and your breakage shall be minimum. now if you want to bounce off rocks and hammer down then a more robust axle should be considered. however a built up d30 trussed is fully capable of handling 35s for sure. bigger advantage to a 44 vs a 30 is a larger ring and pinion. also stronger and rebuildable/serviceable wheel bearings and that is what most should be after when considering axle upgrades per their desired tire size.
there's an idea behind building rigs and building it i a way that if you do break you can somewhat control, through build options, where it will most likely break.
