I have a 2005 Ram 3500 SRW Quad cab 5.9 diesel with a Bigfoot 1500 ( about 3000 pounds) going on it in the next few weeks. Stock wheel size is 265/70R17. I bought the truck with 295/70R17. There are no rubbing or clearance issues but, they are getting worn and LOUD M/T tires. Although, I do like how the size looks on the truck.
I drive about 75% on road and 25% on forest roads (White rim trail, Death Valley etc.), with occasional snow, rain and mud, mostly on pavement.
On is pavement stability is most important, followed closely by the ability of the tire size(with) to tame those nasty wash board roads (airing down). Road noise drives me crazy as well.
I'm 90% sure I'm going with the Cooper Discoverer AT3, load range E, but open to suggestions. I also need new wheels as 2 of mine are cracked, so open to suggestions there as well.
My question is should I go with a narrower, close to stock size tire, or go with a wider tire?
Is there any benefit of changing my wheel size from a 17?
Or am I over thinking this whole thing?
Thx,
Sean

We had those same as the OP tires on our 2000 F350 with a Bigfoot 1500.
We noticed a slight bulging on the sidewall and less than 10,000 miles later we had sudden tread separation on one tire and the signs of it on another.
While they were on the rig we didn't love or hate the tire, but the didn't give traction in much of anything.
We opted for a M&S tire just to give us a little more traction. Since the Ford is a 7.3 and it's a 2000 road noise is a way of life even with the stock exhaust so we didn't focus on that or tread life since we don't get to put that many miles on the tires each year, for us the truck has the camper on about 90% of the time.
As for skinny vs wide. From my former life of living in the NorthWet I lean toward more narrow tires if I can, better to cut through muck and rain with vs a wide higher flotation tire.
I have had the Toyo AT2 and R/T and the Cooper ST Maxx's in the last couple of years and all are pretty equal in the snow.We went with Method NV HD wheels, 4500# rating and Toyo At2 4080# rating. I'm not thrilled with the wet snow performance of the Toyos. Looking at Yokohama Geolander, Nitto, and maybe the Toyo RT. I see Cooper Stmaxx makes a 4080# tire. I'll make a decision in the next few months. ATs aren't worn out yet.

If what you have has been working, I see no real reason to change it out.
Going wider has both benefits and drawbacks, and the only reason Id push to a different size wheel is for tire selection.
Going wider will net you a higher load capacity though.
Personally, I went to an 18" wheel to get the tires I wanted, in the size/load-rating/load capacity I wanted.
Toyo AT2 285/75R18 (34.8 x 11.2) a Load E tire rated at 4080lb per tire.
Going with these tires with such a high load capacity I'm able to run at a considerably lower PSI that the stock tires.
Softens the ride, increases grip, and the tires are less prone to punctures/damage.
