Currently running the stock crap tires on a 3500 srw LB. per usual i hate them with a passion. Looking at moving up to a 35x12.5 All terrain as i deal with weather (Snow, rain, flooding ect) also at times am off the path in fields, woods, so forth and sometimes pulling something in all scenarios.

Having a 3500 i tow and at times possibly heavy. currently looking these

The load index is 128 and going by the chart they are rated for 3968. is that high enough for the truck?

oh and the "Hey guys will this fit my truck with stock wheels?" LOL
 
The stock tires are a LI of 125, so yes those have the capacity.

They will likely rub with the stock wheels and reduce your effective gearing for towing, also they won't fit with chains if that's a concern.

gotcha. no worries about chains here. if its bad enough (maybe every 5-10 year freak blizzards) for chains im staying home lol. i found these that have a higher rating and not as wide so should be fine. these are 129 at 4k+ i have to look at my truck, i dont think they are much bigger if anything maybe an inch. i mainly need the traction as this weekend i almost slid off a muddy hill into the woods trying to retrieve a dump trailer and well, its still sitting there until this weekend lol

I ran into this a few years ago with mine. You have to pay attention they might be a E rated tire but they made a E1 and E2 class rating. Most tire shops will run off your door tag for rear weight rating. Most all terrain I ran into on 18in wheel would not work. 20in wheel will havevway more selection as the side wall is stiffer. The compound on 3 peak tires is a lot a softer.

I ended up with Toyo AT3s and F clas rating. They ride just fine and don't they are F class.

Door tag rear end rating and divide by 2 and that's what you need to meet or exceed.
