Seems like the Toyo Open Country A/T III will now also be available in 245/50-20 along with the Falken Wildpeak A/T Trail and both are 3PMSF rated. I'll likely be installing a set on my Ascent for my winter adventures in the next month or so...just sharing the find in case no one knew!

Those look nice!

I hope I'm not hijacking this thread by asking a question.

I will be driving our Ascent in northwest Minnesota during the winter. I'd rather not change wheels because I'm not real knowledgeable, but I could.

We do a fair amount of highway driving up there because the house is in a rural area. So, it will be a mix of snow plowed or sometimes unplowed dirt roads, but also lots of time on cleared, cold* highway. We try to stay in when it's really bad but sometimes you just have to go restock.

Would I be better going with a true snow tire or an all terrain option like this? Seems like the ATs would be noisier on the highways but maybe good in snow and helpful in the mud in the spring. Maybe I should just get a more aggressive all season tire? Not a lot of options for these stock wheels.

*BTW when I said cold, I recall multiple mornings colder than -30F a couple years ago. Looking forward to the Starlink Remote Start feature!

I think your key issue would be the temperature. For that type of not-crazy, not-a-lot/not-deep snow use, I'd normally say winter rated, 3PMSF rated, highly rated in snow, all terrains would be fine (since it also better satisfies your logging roads needs), except for that brutally cold temperature.

For that, I personally would go with having a winter set and swap to something else that's suitable for the summer... I've run down to -12° on all terrains that got stellar winter ratings, even in blizzards... but -30°?!?! I wouldn't. The rubber compounds in winter tires are designed for the cold. I'd personally probably get something from the Nokian Hakkapeliitta line that's in their extreme cold range.

But, my friends at @Discount Tire could even better inform you, as they've got a LOT more experience with that. And they've got some great prices (and service). I'm riding on their wheels and tires - which replaced their previous tires... on my Ascent which replaced my Outback that ran on two sets of tires from them.

Robert nailed it, you would be fine on A/T tires for what sounds like most of your driving, a 3 peak rated tire would suit you well for most of your winter time driving. Also the tread design and chip and chunk resistant compounds would work good on the dirt/gravel roads to help the tire last longer. There are even some A/T options that many customers use on their daily drivers that are rather quiet and comfortable riding.

With that said, -30 is brutal to tires, there isn't an A/T or highway tire that is going to perform decent in that climate due to the rubber becoming rather hard and the loss of traction would follow.

This is where a dedicated winter tire would do well. The compounds within a winter tire are built to stay pliable in the extreme cold, this is why a winter tire can not be driven in temps above 45 degrees, the compounds would become so soft the tire would wear extremely fast. Here's a bit more information on that. Tires below 45 | Discount Tire

We would be happy to help further, pm on the way!

I also live in NW MN. I'm sure the ideal set up is two sets of tires with dedicated winter tires, but I've lived here almost my whole life and can only think of a few people that do that. Almost everyone I know just runs some form of AT tire and takes it easy in the winter. We've been running Hankook ATM's (3 peak snow rated) on both our F150 and Expedition in recent years with good results on snow and ice. (Expedition is being traded for an Ascent the end of this week, will likely be putting the Falken tires on it.)
-30 is hard on vehicles in general, not just tires, so caution and common sense prevail during those days every winter when we get down there as to how far and how often we drive.
