Toyo OpenCountry AT3 Experience? (10 Viewers)

[hickuptruck]

I would go either P or LT/C. There is absolutely 0 need to go E rated. Your wet traction, mpg, and ride will suffer for no reason. The P will have best snow and wet traction because the P rated has more silica content in the tread. The LTs have less silica because that means less durable/easier to chunk off. E rated tires are for 2500/3500 HDs and Duallys. Its overkill and less traction in the winter because harder compound.

Manufacturer specs indicate different max tire pressure, and often somewhat different weight. I think it's logical to conclude the construction differs to withstand higher pressures and higher loads. Whether they are stronger in terms of puncture resistance it can be debated, but they should be, right?

Also:




From: What is Ply Rating for tires? Here we explain it clearly - https://www.sttc.com/ply-rating/

None of that means the tire will be any better in ways that matter for the use case @phargoh described. In fact, it could very well introduce unnecessary compromise, in the name of adding qualities they don’t need, as @hickuptruck described.

That's possible. I admit I wasn't aware that for difference in weight can be very significant for some tires like KO2. E.g. in 285/70/17 the difference is 6 lbs, which is a lot.

Besides more silica, the passenger Toyos also have more siping.

I have 275/65R18 and now 400miles on Toyo AT3 SL. Ride and comfort is awesome. Only problem I have with them and why I am thinking about returning them is the noise. On highway it overtakes wind noise if that helps in describing level of noise. You can hear those tires at any speed over 40mph.

I have AT3 285/70/17 on RW, P rated SL. Honestly they have been great. No complaints. Look good, perform great in rain and snow. Noise? They are louder than stock but honestly not much. I realize that is subjective, not to bash others. Big fan of the tires!

I'm very surprised to hear that (unintentional pun). Mine seem very quiet. I would imagine my LR3 to be probably comparable in NVH to the 100 series, although i don't know. It is pretty quiet on the highway. If they are making noise, i'm not distinguishing it from wind noise. The KO2s were definitely and clearly making more noise than the wind. I haven't had other tires on this rig so that's all the info i can offer. mine are a CM narrower than yours but otherwise the same.

I do have a full frontrunner rack, with the wind deflector. It doesn't seem to add much noise but it probably does, i've never driven the rig without it.

As a fun aside, I interviewed the engineer at Toyo who designed the ATIII yesterday. He owns three Land Cruisers, including a 200, and used to be a product manager at a little company called Toyota, where he worked on the Land Cruiser program, the 4Runner TRD Pro, FJ Cruiser, etc. You couldn't ask for a more purpose built tire.

Did you ask him about load rating?

 

[WesSiler]

Did you ask him about load rating?

He suggests E. Little to no penalty to ride quality, enhanced durability.

Can’t tell if you’re being serious or not.

It's his direct feedback. Says in testing they just don't notice a lot of differences between lighter load LT ATIIIs and heavier ones, so you might as well benefit from the increased durability. One of his colleagues even runs Fs on his LX570 and says they do fine.

 

[mcgaskins]

I've long stated even on a stock 200, I personally prefer E rated tires. I strongly dislike the way a 100% stock 200 drives until E rated ATs are added, and I hated our bone stock 08 LX until we put on 275/65/20 KO2s. All 5 200s we've had ran E tires as fast as I could get to Discount!

This is nice to hear, I certainly agonized way too much over worrying about which tire to order. I ultimately ordered the E rated ones, since the cost was only slightly more and if you possibly got more durability out of them then bonus, and with almost no weight penalty. Then, of course, came on MUD and was immediately regretful of my decision, since I know I don't need the E rating for my use case.

Either way, I haven't had them mounted yet, they showed up on my doorstep yesterday. I'm sure I would have survived either way, but glad to hear I probably won't be suffering too much for ordering the E rated version.

 

[unclemat]

Well, I've been running E-load rated KO2s (285/70/17) on my 2015. I like them better than what it came on with when I bought it (Michelin Latitude Tour in stock size).

 

[MTExplorer]

In case one more data point helps anyone making a decision on these, I’m running an E-load Toyo A/TIII (LT285 /70 R17 121S E1 BSW) on my 2017 LX570.

So far, I’m very happy with them.

Quiet and comfortable, ride is better than the other tires I’ve had on the truck. (Of course my other two tires were Nokian studded winter tires and stock Dunlop’s on 21” rims). They’ve done well on dry and very wet pavement, gravel, ice and snow.

It’s only been a couple hundred miles, so not a lot of use yet though.

Tires went back. I had SL load Toyo and maybe those have more noise (less PSI, more tire touching ground, etc???) . I see satisfying comments on E-load.

Conversely, I hated the e-load KO2s I put on my cruiser when it had stock suspension. Between the mass and increased tire spring rate from the required inflation pressure they totally overwhelmed the stock shocks. Switching to rock warriors and p-metric AT2s, which was around stock tire/wheel weight and pressure, dramatically helped ride quality.

I guess a lot of this is individual preference.

I’ll be switching to LT tires for my next set now that I have the Kings, but will be sticking to c-load.

This.

There's no doubt in the spectrum of tires, that's there's differences. Our combined subjective opinions help tease those out. Whether P<XL<LT C<LT F, tire model or size. And it plays further upon the overall setup of the vehicle including suspension, weight, additional mods, etc. Then if the difference or qualities meets expectations or crosses thresholds, is a personal choice. From the spectrum of responses and the way vehicles are modded, some seek out the truckish feel of certain types of tires, while others may want to preserve as much of the OEM feel as possible.

Nothing wrong with it, but as a prospective buyer with all the different variables, sometimes with a bit of aspirational goals vs reality, it all can be hard to wade through.
