Truck Tire Time

[SchralphMacchio]

Has anyone here run Kumho AT51/AT52?

I’m sure there are nicer/better AT tires, these happen to be available in a D range index 106 at LT215/75R15. If I go up to a LT235/75R15 I need to replace my wheels with reduced offset due to clearance issues with tire chains. Reviews seems solid for my application, which simply requires good braking on snow and ice and a stiff sidewall, the harsher the ride the better in my case since it’s going on a travel trailer.

I looked at these when I was shopping and didn't come away wow'ed by the reviews. TireRack has the new Falken AT4W in that size/same weight rating for $12 cheaper than the AT51 and the outgoing AT3W $5 cheaper than that. I'd go Falken every day

Minnesota certainly has the climate and need for studded tires, but they were outlawed the year I was born - 1971. We have had extremely icy roads here most my life. There are times I've wondered about studded tires, but then just decided to drive like a sane person, and let the maniacs own the ditch.

My Falken AT3W's have been pretty awesome though.

I guess the fact that they are just about every plow truck around makes me put them in the winter tire category and very few of them are studded. Hak’s are garbage for plowing compared to duratracs. The road noise thing is most due to the sound screen in the lariats. XL and XLT are very noticeable. The sound screen is amazing.

There on lots of plow trucks as they are three-peak mountain snowflake (3PMSF) symbol rated. Some commercial uses require tires with this rating for winter.

Nitto tera grappler(not recon or ridge grappler) and Toyo open country AT3, BFG AT 2 and 3, are all 3 peak rated as well.

I have duratracks on my grand Cherokee for winter and offroad. I like them as an aggressive at that wont gumb up as easy as most AT’s. I run goodyear silent armor in summer(much quieter especially for higher speed summer driving).

My next set before next winter will be Toyo AT 3. Have 2 buddies who had good results with them this winter. More sizes in C range and lighter. I hate D or E unless its a 2500 or 3500 truck hauling/towing.

The AT52 are part of Kumho current rebate offer ($80 off 4). The AT51 are discontinued and replaced by the 52.

I just ordered a set of four AT51 for my truck from Amazon, as they are priced cheap right now - - 265/70/17 load range E are $144 ea. I read a bunch of reviews and they're OK - - snow traction seemed decent to good, but there were many complaints of short tread life. For my truck, a 30-40K lifespan is fine, it doesn't see that many miles per year.

[El Chupacabra]

Scratch that, I got a better deal. Canceling my Amazon order.

Instead, I got Discount Tire to do a price match on the Kumho HT51, same size and E load range, at $155/ ea. This tire is basically a copy of a Michelin LTX A/S, has a 3PMSF rating, tons of good reviews. And it's on Kumho rebate now. Total for all four installed, after rebate, will be $666.

Time to get new summer tires for my minivan. Non-LT AT tires. We’ve been using the Yokohama geolandar AT tires for years on the van, but I’m seeing the general grabber, toyo open country, and falken wild peak a/t trail are all a little cheaper. But they’re all apparently heavier than the Yokohamas. Anybody have data regarding mpg loss with a heavier tire?

[SchralphMacchio]

How much heavier? Heavier should theoretically mean lost mpg due to higher moment of inertia, primarily this would be felt during acceleration after coming to a full stop or just heading through congestion.

[bodywhomper]

When I started looking online over the weekend, I first saw a customer comment about the generals being heavy and causing them to lose 2-3 mpg. They didn’t provide other details like tire size and what tires they were previously using.

According to dealer website (discount), the weights range from 27-30#. Not sure what size they’re reporting. I haven’t looked too closely to see if weight by size is listed somewhere.

[J. Barron DeJong]

I’d guess that differences in tread pattern, rubber compounds, and carcass construction would have significantly bigger effects on fuel economy than differences in weight would.

[carlh]

I have falkens on my pilot, they are fine but I get slightly better mileage with my slightly smaller conti Viking contact snows. I briefly had a set of terrain contacts on my q7 before it got totaled and I think they might be better for mileage and rain but worse in the snow.

[El Chupacabra]

I’d guess that differences in tread pattern, rubber compounds, and carcass construction would have significantly bigger effects on fuel economy than differences in weight would.

I'd agree with this. But - - a brand new tire that is the exact same brand, model, and size as the old worn out tire will get worse mileage because it's new, full depth tread, grippier, etc.

If staying with the same size and generally the same style (all season, highway tread, AT, whatever) then I wouldn't expect a gigantic difference.

I think my point is just that if you’re trying to figure out which of the new tires you’re considering is going to provide better fuel economy I wouldn’t assume that looking a tire weights is going to be a good guide.

Agreed.

There are tires marketed as "low rolling resistance", but I don't know how much real world difference there is. Something with a crazy high tread wear rating is probably a harder rubber and will produce better MPG, probably at the expense of grip. (Michelin Defender comes to mind.)

[bodywhomper]

The weight comment that I saw threw me off, which is why i posted the question.

My toyo open country AT3 have been great on my forester. Not sure on mileage but seems down a bit. Biggest thing is how quiet they are for an off road tire

How are they for winter driving?

[The SnowShow]

Following up. Should I look at the new BG KO3s, new Falken AT4ws or Toyo Open Country AT3s for good summer/fall off road tires with good winter performance to get to the CO ski areas?

In the same boat, just traded in my 2005 4Runner for a 2024 and need new shoes. All 3 of those are on my short list, plus Hankook AT2s. Leaning towards the Falkens.

I don't really know much about them but I just bought a set of Falken Rubitreks a couple months ago. They look good but I've got no snow report yet.

[SchralphMacchio]

The Falken AT4Ws only came out this year so most people don’t have on snow reports. I’ve only seen design analyses saying that it’s anticipated that snow performance should be somewhat reduced from the AT3W due to changes in siping and block design, but all that’s still not clear until the rubber meets the, er, snow. Especially if the snow performance deeper into the life of the tire actually ends up being better, because they seemed to use denser material and/or maybe more material in the AT3W, more on that later.

I did put them on my travel trailer to replace ST tires. Given that it’s a totally different application and they also haven’t been in snow yet I won’t have much relevant comments to say yet, other than these observations:
-look at the size charts to see the weights of specific tire sizes, the AT4Ws are significantly heavier than other comparable tires in class in the same size. That could be a good thing (longevity, dampness, durability) or bad thing (efficiency) depending on what your objectives are.
-They do feel quite damp on high speed hits (like expansion joints and short dropoffs or small bumps), but that’s me feeling the sensation through a tow hitch vs under my seat, plus it’s in comparison to a highway ST tire so again I can’t really say how it would translate to your truck.
-they are really stinky, the outside of my RV was smelling like I didn’t flush the black tank for weeks after I had them mounted up.

[ASmileyFace]

Been considering this over in the "all weather tire thread" and settled on KO3s being a good candidate for my use case. They apparently arrived at my local discount tire this week. So I am going to give em a call and see if they have a set. Quoted me at ~$1400 installed when I went by a few weeks ago... tough pill to swallow there. They also had a set of AT4s which were less expensive and which might sway me that way in the end as I still have a dedicated winter set for the completely snowpacked road months.

[MagnificentUnicorn]

If you have dedicated winter wheels and tires the Goodyear Wrangler Trailrunner AT is a really good value and great all around AT tire.

Considerably less expensive than the current popular AT bro crowd models.

I don't, but ran a similar tire (BFG TrailTerrain) with good results even in the snow. Thanks for the beta on the Falken AT4Ws, Schralph. Weight is definitely a bigger consideration than durability and longevity for my situation.
