Good choice IMHO on the Michelins LTX/MS. Good luck.

If you get new tires you could consider 18 rims and 275-70-18 load range E w/126 rating for over 3600lbs each. It adds only 4.5% to the size. They are used for the F350 SRW.

Nitto LT285/70R17 E126R is rated for 3750#. Toyo also makes e rated tires with heaverier loads. You do not need to change from a 17 inch wheel to achieve this.

The 17" wheels from Dodge don't carry a 3750 lb rating.

My factory stock 17" aluminum wheels with OEM Michelin LT265/70-17 E are rated at 3400 lbs

The RAWR is 6000#. A 17 inch wheel rated for 3400 pounds and a tire rated at 3750 would be just fine if you stay within the RAWR of 6000#.

Actually, the GAWR (rear) is 6500#(from Ram Towing Chart). If I get the 265-70-17 E rated LXT MS/2 tires, they are rated at 3195# each. This would be 6400# or just under the GAWR (rear) - which I don't want to exceed. So, is there still an advantage to getting tires that exceed the GAWR (rear) even though I will not be exceeding it (the pin weight will bring the weight on the rear axle to around 5800#)? Do folks think that that is cutting it too close? - 600# under the rating of the tires. Thanks all

My Nitto Terra Grappler 285/70R17 tires are rated at 3750@80 PSI. There are Toyo 17" tires with this load rating as well.

But I guess in the end, with my RAWR at 6500#, do you think I need (or would benefit from) tires that will exceed the RAWR by 1000# (3750 X 2 - 6500#= 1000#)?
