BFGoodrich AT KO3 vs Bridgestone AT Ascent vs Cooper Stronghold AT - Which Should You Buy?

Video Overview & Insights

The BFGoodrich All-Terrain KO3, Bridgestone Dueler A/T Ascent, and Cooper Discoverer Stronghold AT are three of the most popular all-terrain tires on the market. But which one is right for you?

The site REALLY needs all terrain tire reviews, get on over to https://www.tire-reviews.com/submit.htm and review yours :)

— @tyrereviews

In this comparison, I test all three tires in the same size (LT 275/65R18 E) on the same vehicle at the same pressures to find out how they really differ. I cover on-road comfort, noise levels, steering feel, and off-road traction on my desert test loop.

What I found:

Can you test the new Bridgestone Maverick AT from discount tire

— @loganshirley476

- BFGoodrich All-Terrain KO3 - Impressively tough and quiet, but also the heaviest (58 lbs)

- Bridgestone Dueler A/T Ascent - The comfort king with the best NVH, but steering feels lazy

Can we fit 245 50 20 in 20 inch wheels honda crv hybrid touring

— @rajanjitsingh4420

- Cooper Discoverer Stronghold AT - The sharpest handling and best off-road balance, but firmest and noisiest

Quick Specs:

KO3 is anything but quiet

— @Will-s6c9p

All three are 3-Peak Mountain Snowflake rated and cost within $10 of each other on TireRack.

The KO3 is heavy as hell. My truck feels as if it has lead on its wheels....and the major downside it that the truck does not want to turn which is obvious ...

Here is the link to the wonderful tirerack test https://www.tirerack.com/tires/tests/taking-off-road-tires-on-road?ttid=337

Be sure to follow TireRack on YouTube too.

I replaced the stock all season tires that came on my 2025 Ram 1500 with Bridgestone Ascent A/T because I wanted a year round tire that was comfortable on the highway and also 3 peak rated for Nova Scotia winters. I’m very pleased with my purchase. No A/T tire is as good as a dedicated winter tire but these are certainly better than other A/T tires I have used in the past. I can’t speak to the off road capabilities as 98% of my usage is on road or well maintained gravel roads. Would buy again.

I do recall you having a video on the Toyo open country AT3. In terms of noise and comfort, which tire would you recommend the Cooper discoverer stronghold AT or Toyo open country AT3?

0:00 Introduction

I had the Cooper strongholds on my old truck, K02's before it. I was at the end of the K02's life with better wet and snow traction than brand new/broke in on the Cooper strongholds. Slid out on the highway in barely wet conditions, frequently spun in 2wd well gently accelerating in a dusting of snow. Never even thought twice with the K02's. Coopers handled very well on gravel and dirt for me though to it's credit, but not better enough than the K02 for me to say it's worth it.

4:45 On Road Comparison

I’ve always used cooper….i love them. I’ve never had a blowout or tire failure. I live in snow country and they are excellent. Yes I’m bias but they are a kick ass tire

— @Rky-pr7zh

10:10 Off-Road Comparison

13:09 Snow and Wet Data

I have the Bridgestones on my f250. They are great in the snow and quiet. Where they struggle is on wet roads. I have to accelerate slow from a stop or the will break contact and spin. Did not have that problem on my previous Destination XT’s.

17:20 Conclusion and final thoughts

KO3 is absolutely the worst tire ever 👎👎👎

Does the bridgestone at ascent out perform the firestone destination A/T2 that was a top tire in the last all terrain tire test?

@chaddyuan8189

This is one of the best presentations for all terrain's I have ever seen. Video presentation actually correlates with the dialogue in the on road test. You hit on some very valid points especially giving us the size, load rating and the pressure during testing. Reviews on tire rack and discount tire suck because no one tells what size, load rating and pressure the tires are reviewed at. Observing the reviews it looks like a lot of people don't even know there is different sizes, load ratings or the correct pressure for the application. I've read where some people say (I run the max pressure) which for E rated tires is 80 psi, and then they wonder shy the center wears out fast. Or they run pressure to low and have a sidewall blow out. Some of them reveal this but very few. I absolutely hate AI presentations. Lazy ass inaccurate info. I will never subscribe to that crap. Good job man, I'm subscribing to your channel.

I have older COOPER discoverer tires, they are very quiet on dry pavement.

That’s the most on-road “off road” test I’ve ever seen.

At that point, why not just drive down a gravel access road and call it a day?

We have state park roads worse than that.

Useless test.

@JeffJBuck

The KO3’s are superb in all conditions. Smooth ride, low noise, pushes the rain out, etc… I’ve had BFG original KO’s and then went with Yokohama Geolanders, not even close. Running on a Hummer H2.

How does the Nokian Outpost Nat compares to this three, in the same test?

@jessdmppl
@

Nokian Outpost NAT. That's where it's at...

@Maplehornet416

Don't know where this video was produced but is it too much to ask to dump all these Brits yacking at Americans. I'm sick of them. Announcing Olympics, Golf, Yellowstone wildlife reclamation and so on. What happened to Americans talking to Americans? I don't even care what he has to say about tires.

@Northland11899
@

Okay. I’m between the ascent and Nokian outpost nat for my tundra. Looking for mostly on road comfort and noise. I tow a few times a year a camper and horse trailers. I will be driving these mostly in the summer as I have dedicated winter tires, and both will perform enough for the surprise snow storms. I sometimes hit off-road but nothing too crazy. Which would you pick? I’m assuming the ascents. (I’m a Nokian fan lol)

@ianpaddick2003

Thank you for your content. Good stuff!

@bfed2831

You should have explained the weighting and difference between LT tires and SL standard load tires.
I had to find out I ordered the unnecessary 10 ply cooper crap show ones because of this poopy not detailed video 👎 💩
Thanks for nothing but a headache

@Warden1977

Dueller Ascent put on my Ram 1500. It did really well in snow (even though we didn't get a lot of it this year) and is very quiet on the road. Haven't taken it off road a lot yet but I expect it to perform well when I do.

@stycks32
@

I had the k03s on my 2024 Tacoma but I wasn't impressed too much with them in the rain. I don't think the Z pattern helps that

@propotatoman

I just discovered your channel. Excellent real world conditions reviews. I currently have the Cooper Discoverer AT3. They have been great. However, I do have to rebalance about every 5-6mo. And past 72 mph there is a noticeable vibration. Dirt road, and wet conditions are where this tire excels. The noise is not loud and is the same tone as regular road noise. I’m now about a year out from a new set and your video has me convinced that the Bridgestone ascent is my next tire. I will be more on the highway in the years to come and less on dirt roads. I have a 2020 Silverado crew cab standard bed( not short box) 4x4.

@matthewholmes6428

These Bridgestone Dueler A/T are complete junk boys. I go offroad ALOT on hard tracks pushing my 4x4 to its limits and the Duelers are complete junk. There a highway tyre with a bit of offroad. They will not bag out enough there super stiff ive been using these for a while and cannot wait till there worn down enough so i can go with Yokahamas or Mickey Thompsons ATZs. I regret buying the Bridgestones every day im on the tracks.

@DIFFLOCKERS
@

I put those Bridgestones on my X5. Ran them on some snow and ice, I'm impressed, with T/C in 'middle' mode after tromping the accelerator after a few seconds of slip i was up to 45-50mph without much hassle... I know these tires wont take me to places my M/T tires on my Nissan will but that isn't the point here. apples and oranges. so far very happy with the duelers. Very nice for the 80% on highway and capable enough for the other 20%.

Had KO2s switched to Wildpeaks and never going back. BFGs are trash if theres any water on the ground. Wildpeaks all day everyday

Great review!!! My OEM Goodyear Territory are stone magnets, looking for a tire that eject stones well! After your run down the gravel road which tire had the least amount of stones stuck in the thread? Thanks!! :)

@dman7165

I've been following your channel for about 5 years now, and I'm quite picky when it comes to tyres. What concerns me is that I reach different conclusions when comparing tyre sizes, particularly 225/40R18 and 235/35R19. For example, in some of your older tests, the Michelin PS4 in 225/40R18 finished well ahead of the Bridgestone Potenza Sport, but in the new 2025 tests, the Bridgestone in 235/35R19 came out on top. Would you have the time and interest to compare 3-4 top brands and assess their consistency across the most common sizes, e.g., 205/225/235 in 17/18/19-inch diameters? From what I've seen, only Continental shows real consistency, while the others are scattered all over the rankings.

@Joske0000

I've burned through all 3 versions of BFG AT KO but now am using the awesome Nokian Outpost NAT which I think is actually superior in many ways.

@jwestpro

Because of the snow performance and where I live I chose to go with the KO3. I put those bad boys on my Ford lightning battery electric pickup truck. Run them at 35 lb and there is not anywhere that I can't go. In fact I've been going in too deep of snow and it's been going into my radiator. I've been having too much fun!

@Rxi807

I just went with cooper discoverer rugged trek and absolutely love them. They ride very smooth and the road noise is very minimal for an RT. I had Goodyear ultraterrain AT before and they were great tires also. So far I think i prefer the coopers.

@Civiliansoldier762
@

I would like to see, tire balance, added as a data point. How much weight does it take, to balance each tire. Balancing can show how well a tire is constructed.
Thanks for all your hard work. Well done

@bearfoot100

Great video. I like you were weren’t biased and gave pros and cons of each.

@xamitz58

Really need to do the Cooper Discover Road+Trail AT as well. A little more road oriented, but one of the best wet weather tires I’ve ever run on my truck and snow performance was shockingly good. I also do not hear the tire at all compared to the KO2s I had before.

@CoorsLightyear
@

Hi, if you buy a new tyre, and the date code says it is 3 years old. Is that ok to use?

@Kilenny76

I use and trust Balance Beads for my truck tires.

Appreciate your review. Sounds like the Bridgestone's are for me. 2026 Honda Passport.

@EnjoySoy

I had the KO3 last winter when they came out, they were hot garbage on snow packed roads and mediocre in rain. So happy to have the Ascents during this current snow storm.

@GeorgeL.3

Bridgestone for most by far. I have owned the ko2, open country at3, scorpion atr, cooper at3 xlt. All LT sizes e rated. The Bridgestone is by far the quietest on road has the best siping for winter and rain. Still looks the part but not quite as aggressive as the others. No comparison on highway. I respect your reviews but the tread pattern don’t lie. The Bridgestone looks like the best of the road and it is by far. And quietest by far.
