BFG KO3 Tire Reviews

I've got a '22 2500 AT4 and just replaced the original Goodyears that had just over 55k miles on them with BFG KO3's. So far they ride smooth and are quiet. I've got no complaints so far, hopefully they'll be a good tire. Most of my driving is freeway with limited off road and mud. The original Goodyears served me well also.

I spend a lot of time on the truck and jeep forums, and I’ve learned a lot from this community and the others, but the one topic that never produces meaningful consensus is tire reviews.

Tires are like boat hulls. Every design change involves a trade. Want improved wear without changing the tread pattern? That’s likely to mean a harder rubber compound, and that’s likely to mean less traction on the road. Want better traction in soft mud? Then you’ll need an open-lug pattern that digs and clears easily — but that will trade traction on pavement, and particularly icy pavement. Want super quiet tires that optimize performance on pavement, then you’re going to give up traction in the greasy stuff.

In my experience, internet opinions are heavily influenced by where people live, how they use their trucks, how much experience they have, and how they balance appearance and functionality. People who make it home in a snow storm will think their tires are great in snow, even if they weren’t particularly challenged by it, or it was particularly sticky snow. Also, although this might sound/seem stupid, a huge proportion of people buy tires based on looks…

I’ve had multiple sets of Toyo MTs on Jeeps and HD trucks. They wear great, carry weight great, dig mud pretty well, perform okay on rocks, and make little noise compared to other MTs with similarly aggressive tread. They’re also heavy, and loud compared to most all-position options, and they’re terrible on ice.

Want a tire that’s super quiet, wears well, and has good traction on packed snow and ice? Unless you’re going to run studs, you’ll need an all-position tire with a tighter tread pattern. KO2s are very good. My Toyo MTs would not make it up the first 30 yards of my driveway in the winter, even with a heavy diesel, a heavy tool box in the back, all four tires spinning, and a 20 mph run at it. Running Toyo MTs on sheet ice was like trying to run on polished concrete wearing football cleats. (Tennis sneakers work better for that, but they’re not worth a crap on a muddy football field, right?) I drove my truck to the tire store, bought a set of studded Duratracs, and easily drove up our driveway without a slip. My wife’s jeep made the same trip running BFG KO2s with a little more slippage, but no problem.

On the other hand, I ran KOs on two heavy F-350 diesels. They are terrible in mud, because the pattern is too tight and they don’t dig and clear well. I also had two major butt-pucker events when I hit standing water on the interstate at highway speeds. On both occasions my heavy diesel truck hydroplaned for long enough to pucker my but — because the KO’s didn’t evacuate water well. ((Running 35x12.50x16.5s). That never happened with the Toyos MTs or Duratracs, because the open tread patterns on both evacuate the water between the road and tire.

I live in the mountainous northwest where we get a lot of rain, mud, snow, and ice. For me and my uses, the best combination has been studded Duratracs in the winter (no longer made after 2024) and BFG KO2s in the summer. I have no experience with the KO3s, but tires are definitely improving with time.

The best overall assessment of relative tire performance I’ve found is the summary scoring charts published by huge tire retailers that sell many brands. At least they’re based on thousands of customer reviews over millions of miles. Those charts are still influenced by where most of those folks live and drive, of course, but at least the wear information is helpful and the influence of one-off freak incidents is reduced. On internet forums you’re equally likely to get a great review from a guy who has driven only 2,000 miles of highway, or a guy who had a sidewall failure due to under-inflated tires creating a pinch in ledge-rock… or even a guy who based his terrible wet traction assessment on a tire slip in the first rain after two months of summer sun. (In the northwest, we often have five or seven weeks of dry sun in the summer. The first rain of fall always produces LOTS of crashes, because when the summer’s accumulation of road oil is mixed with the first rain the pavement becomes as slick as ice. The pavement washes clear after a day or two of rain and traffic, but anything and everything will spin an hour into that first rain.)

I’ll see if I can find links to TireRack or Discount Tire summary tables and post them below.

Here’s one example of such a comparison chart. There are about a dozen such “research & comparison” charts under “Light Truck Tires” on the TireRack site, depending on whether you’re shopping for tires that lean toward on-road, off-road, winter-traction, mud-traction, etc. This is just one retailer, but I found similar data compilations elsewhere.

I bought 20" Ridge Grapplers (116T) about 6-momths ago. Louder and more vibration than the OE tires (not Goodyear). My wife hates them, so I'm thinking KO3. Anyone have experience yet with both from a ride quality and noise comparison?

You got the real K03s! The ones that came on the stock HDs were different. Just found this out.

I have the KO3s on my 24 AT4 HD. I find them surprisingly good on the pavement. No noise or very little (granted I don't even have 5,000 on the truck yet), they handle quite well, and good in the rain. Haven't had it in snow yet but I've heard the KO3 should be every bit as good as the KO2 if not better in the snow. I don't off-road in my truck so can't comment on that either but I suppose they would be decent if you did.

Tirerack calls them "alternate sidewall design" which I believe are the ones that come OEM. Can't personally tell anything different about the sidewall but the alternate (OEM) is 15/32 and 63lb per tire, the other is 16/32 and 62lb per tire. Don't know how they managed a lighter tire with deeper tread. To be honest: at $424 per tire I'll gladly take the 1/16 less tread depth on my OEMs and not have to go out and spend big bucks for tires on a brand new truck.😁

Yes, mine are the newer style KO3's. It's not just the sidewall that is different (extends further and redesigned mud ejector). The actual center lug pattern is different from the original KO3's. Additionally, the center lugs are now interconnected as opposed to the original KO3's which were not. I was surprised at how much difference there actually was between the two. I'm not a "brand loyalist", I just want to get my money's worth from a tire. The other post that talked about opinions based on use is spot on I'd say. It really depends on where you drive, the conditions, and ones expectations.
 

I continue to be very pleased with the KO3... my opinion is it probably isn't as good as the KO2 in mud conditions due to its tightly placed treadblocks. However I find it very civilized on the hwy, great in rain, and very stable towing heavy loads.

I liked them on my HD so much I put a set on my toy, Colorado Zr2. They are equaly amazing. 80mph and it feels like a michelin on the hwy.

Regardless of which version, for an OEM tire, I'm very happy with them. Much better than the alternative the GY Trailrunners. Or the GY SR-A's that came on my 19 Duramax...even worse.
