******* UPDATED INFO********
I got more or updated info from the owner last night.
Stock tire size was P275/60R20 with max psi of 35lbs.
Aftermarket tires are: 305/55R20 w/ max psi of 50lbs and weight rating of 3,086lbs. Info on sidewall says that the tread is 2 ply steel, 2 ply polyester(?) and 2 ply nylon. Sidewall is 2 ply poly. No mention on aftermarket tires if they are a P or LT (not stamped on sidewall). No load range rating either.
Axle ratings:
Front: 3900 lbs
Rear: 3900 lbs.
GVWR: 6700 lbs
Owner thinks that with the "Punisher" pkg, the hp on the motor is 455.
Not sure of rear end, but has a 12 bolt axle cover. Does this mean it's a Dana 44? Axle dia is pretty large.
Hope this helps those in the know about Dodge/Ram specs to in turn help him.
Again, Thank you.
