2500 Double Cab Gas 4WD & Snow


Recommended Posts

I have the 2015 Sierra 2500 HD and been through two winters with no issues at all with the factory tires. I'm running the 18" Michelin's with chrome rims and the long bed. Same truck just long bed...

 

Great truck...you will love it!!

Long box regular cab here in southern Ontario. Bought my 1st 4WD back in '81. I've never weighted the trucks, but put the truck in 4Hi when the roads are snow covered.

 

One word of advice is that wide tires are not your friend. Even when my brother & I were running large mud tires on our trucks, the P235s (OEM size on the early 80s 1/2 tons) went back on in Dec'.

The stock Michelin LTX AT2's that came on my 2500 double cab were a complete joke for the snow and gravel roads I deal with. After enough cursing at them, replaced them with BFG AT KO2's. World of difference. I had no desire to put on much larger/wider tires, just better ones. If you mainly stay on hard surface roads, a dedicated winter snow tire might be your best bet.

CCSB, stock tires, no issues in WI winter. I add some weight to the bed to help.

 

I will say though the part-time 4WD would be nice because we get plenty of days that offer a mix of slippery patches and light snow where full-time 4WD could cause issues.

Regular Cab Long Box here. I have a second set of wheels (for the sake of keeping the originals in great shape) for winter. I put a set of snowflake rated AT tires (Wrangler Silent Armor ProGrade) and had no issues. No weight in the bed save for when my sled was in there.

When you say part time, I take it you mean Auto-Trac (or the equivalent)? Part time 4WD wouldn't make any difference from a full time T/C when running on a highway w/ patchy snow cover.

Yes, I was referring to the AT system from the 1500s.

"Full time" 4WD more or less disappeared in the early 80s when the OEMs discontinued it & the NP203 transfer case. "Part time" became the norm w/ the new NP208 case. I think Ford used a Borg Warner case.

 

Jeep had their Quadratrac system which I think was an early version of torque-sensing/splitting 4WD.
