What have you done to your K2 today?

No I wasn't going fast to start with, it actually slid in pretty slow. The shoulder was just black ice, no matter what I did it kept going towards the ditch. I'm sure there are some scratches down the side, but I'll deal with those in the spring, when I detail the truck...

Yes, Black is not fun to deal with. Glad it wasn’t bad. Before I got better tires, it was like ice skating where I lived.

I don't know if I'd have the same factory tires as you, but I'm very disappointed in mine. I never had real 'snow' tires on my old truck, but it was pretty sure footed with some normal A/T tires.

I don't love my wheels either, so I may just replace both here this spring.

I actually have Hurcules Avalanche Xtremes on the truck, which is a winter tire. But, it doesn't matter what tire when its black ice...

Got my 2015 GMC a few weeks ago and every day I try to undo something the previous owner did. Seems he had problems with gas milage, (as did I) but had some odd ideas how to fix it. He had the tires pumped up to 70 psi. Yikes! Refused to change the air filter, which I admit looked fine, but at 50k and $20? Really? So then I guess in some misguided act of frustration, he traded it in. Probably made a salesman happy. So new filter, cleaned mass air flow sensor, cleaned throttle body and tire pressures returned to spec. Sea Foam, new tank of gas and a a 30 mile romp in the county and it went from 11 to 18.3 avg on the trip meter which may or may not mean anything. Oh and I keep washing it, but it keeps snowing.

You guys should have just gotten a midnight edition. Comes with duratracs from the factory! This new 6.2 gets around way better than my duramax did.

If you do the math and testing you will find higher pressures to a point will save more than enough money to cover the faster tire wear and keep money in your pocket. The factory SA tires ran around 48 to 50 psi got me between 2 and 3 mpg extra.

I know it makes a bigger donut which translates to lower rippems and overall better fuel economy, but the guy was nuts cranking them up to 70 piss eyes. Still got crap mileage because the problem was not in the tire. Air, fuel, spark. It wasn't getting #1.

Josh154 · February 9, 2018

I’m assuming 10 plys at 70 psi?

Yeah, 70 is way to much. The main savings come from less sidewall flex reducing rolling resistance and it increases noise, vibration, and harshness which can be annoying in some vehicles.

I've run Duratracs in the past, they are only good for about the first 20k km. After that they are loud and not so good on hard packed snow.

If I had a 4wd and lived anywhere that snowed the first thing I'd do would put Iroks or MTR's on. Iroks are more aggressive but they have more lug noise than the MTR's but functioned VERY well on my old Toyota crawler on just about any terrain.

Daly · February 9, 2018

After years of driving in the snow I can tell you, the first tires to slide off the road are bald tires, the second tires to slide off the road are Iroks and big mud tires just like them. They are no better than bald tires. Snow isn't the problem, it's packed down snow and ice... And nothing short of studded tires and chains (both not legal for road use in my area) will help you on black ice.

Welp, found some dead spots at the top of the infotainment screen, and fails on recalibration every time. So, off to dealer for a checkup and free wash next week. Good thing I have GM extended powertrain and accessory/electronics-electrical warranty. Now I get to see what it's worth.

In the meanwhile, milage seems to be on the uptick, even in the snow and with AWD on. Riding better with proper tire inflation, but still on the fence with the Ranchos. I do about as close to zero off roading as you can imagine, so I don't require an aggressive shock. Don't tow or haul much, but it does happen.
