I've had my MY2004.0 CTD quite a while now. Am looking at replacing all the springs on this 2WD 2500 as age has taken its' toll and both the CTD and the TT will be near GVWR (18k GCWR). Might not be much margin left on OEM spec tires/wheels once hitched and WD applied.
Have always been curious abou the 19.5 wheel/tire "option":
Q #1 Is anyone running this size on 2WD and, if so,
Q #2 Are changes necessary (such as raising, "levelling", the front end)?
A correction/addition needed here:
" . . So if you want to talk design limits then you should know what they are first. Rundown of my truck, and any 04-12 Dodge and most 03 diesels.
Front axle and suspension, same 2500 to DRW. All rated at 5,200lbs(03-09) or 5500lbs (10-12)depending on year.
Steering, same 2500 to 3500 DRW on diesel. DRW gas gets hydro boost that SRW doesn't have.
Frame. Same, give the same wheelbase, 2500-DRW.
4WD and 2WD have differences
1] The 2WD MY2004 FAWR is 4,750-lbs. Tire pressure recommendation is 50-psi all around when empty.
(Why I have a thread on TDR asking for 3rd Gen final iteration [MY2009] 2WD spec from any other owner to post door placard spec. The OEM spring rating is not really to par and neither is the pressure recommendation).
2] Steering is rack & pinion
