As far as true snowtires are concerned I used to run studded Firestone Winterforce tires on my Ramcharger and they worked exceptionally well in the winter. I just hated having to pull them off on April 1st.
Goodyear Wrangler Duratracs (while not a true snowtire) are supposed to be very good in the snow and they are studdable too.
Last fall I put a set of BF Goodrich KO2s on my wife's Cherokee and I was amazed at how well they did for not being studded or a true snow tire and we had more ice than snow last winter!
I've been seeing during my research is a lot of "truck" tires can be hit or miss. I can find dozens of reviews for most tires claiming they're awesome in snow and then claiming they're garbage.
Duratracs are supposed to be awesome in the snow for an aggressive AT tire. Mine when I had them were horrible in the snow and rain IMO. Same thing with the K02s. I've heard great things about them but then also heard people say how they're the worse tires they've had.
I'd personally go with a good AT tire (ko2, duratrac) and just drive slow. but its always safer to get a dedicated set of snow tires. Personally I love the "general" brand. I ran their all seasons on all my cars. But getting a full set of snow tires can be costly and annoying to do. but hey its probably less annoying and costly then sliding off the road into a tree.
for an example heres two different reviews for the same KO2.
20,000 Miles on Tires
June 08, 2017
I didn't care for the first generation of "Knock Off" all terrain tires made by BFG. They wore unbelievably bad, chopped terribly on solid front axle trucks, transmitted unwanted road vibrations, and bumps directly into the steering and suspension, and howled loudly while doing it......Guess what? The second generation of these "Knock Off" tires are exactly the same. The only thing they changed is the tread pattern they leave in the grass, when you slide off the road into the shoulder hoping for some traction before you reach the ditch. I admit, I believed all the hype, and I thought having been bought out of debt by Michellin, maybe there was a slight chance these generation 2 tires would exceed my low expectations of BFGoodrich..... Well I threw 1,300 bucks into the Tuition for the school of hard knocks and learned my lesson, AGAIN! If you like the BFG's you had on your 1984 blazer and they lasted in the garage for the whole 27 years you owned it. I won't talk you out of these worthless, waste of valuable rubber, balloons, but if you're in the market for a long lasting, traction on your, every ---- day, work truck! Buy something else. I loved every mile on the 3 sets of Michellin LTX, but they are very limited in sizes, hence my regretful purchase of these noisy, bouncing, excuse for an over priced, wheel protectors."
80,000 Miles on Tires
November 20, 2015
i have used these tires since they came out. its great tire, average 80k plus on tread in mud snow, rock, and highway. i ranch, and work off road, sometimes 100 miles from pavement, so there is creeks and rivers to cross. i currently have these on a 2wd, and it handles just like a 4 x4. i have been in 3 feet of mud, water, plowing thru 4ft snow drifts. crossed mountain passes on iced slopes without chains loaded and towing. some slippage at times but they always bite. i have been on highways with 12 to 24 inches of clear ice going 70 around switch backs and steep hills and drop offs although i personally wouldn't recommend trying. its best not to drive in a lot of the conditions i push these tires to. i have even driven on cobble, although forget comfort as it is rough. dirt roads and gravel are not a problem even when there's loose rock or dirt, can hit a corner at 60 and throttle and wont loose traction nor slide. not bad for 12,000 pounds. i have found the front does best with a tire at 45 to 75% wear. they slip more new, especially some hydro plaining on smooth pavement when covered in water, so put new on rear, break in and put on front."
Granted I see more good reviews then bad but out of the dozen+ bad reviews, does that mean they're all lies?
What about my own personal experience with my duratracs? My jeep was horrible in rain and snow, hell I almost got stuck on a muddy field because I couldn't dig in and get traction. Yet there are probably hundreds of reviews saying something different.
Also on tirerack.com the ko2s are rated 9.1 out of 10 for winter weather. so I'd imagine its a good bet.
