New Toyo Open Country A/T III tire

Yeah, it took a while for me to figure it out. Everybody said it was based on Japan or US for a while (I think Toyo even said that), but that definitely isn’t true. Only thing I could come up with for certain is that all SLs are mild, and every LT in 15” or 16” is mild. Everything else 17+ LT that I’ve seen has been aggressive. So your C rated LT 285s should be what you’re looking for.

 

@BLtheP why do I feel like a scientist doing laboratory research on the mild / aggressive patterns of specific Toyo tires. I feel like I could write a thesis at this point. You may have cracked the code though.

 

It's confusing for sure. The SLs I can understand. Most brands SL tires are more mild than the LT equivalents. SLs can endure less, so you don't want them to look overly aggressive or else people will go tear them to shreds in the rocks and start complaining. But the smaller wheels having mild LT walls makes no sense to me at all. It is the one downside to me going back to 16" wheels, is that I may go with heavier LTs for the longer tread life, but they're extra heavy because load E and they still don't even have the better appearance.

That and the ability to get a load D in the stock size is why I'm kind of looking at KO3 next. But the Toyos are just so smooth and I'd rather have them overall. I still have some time on my current SLs, so I guess I'll figure it out later.

 

@blthp yea toyo has some C load but the crazy part is 285/70/17 in C and E is 55lbs confirmed w the toyo rep and right off their website. No difference. I went with the C for better on road ride. I looked at the K03 in C load same size and it was 56lbs.

I’m coming off of a set of ridgegrapplers 285s in SL. They seem to maintain an aggressive appearance in SL and weighed 48lbs. I’m just sick of them. I liked the ko3 but I was already Up there in lbs at 55 w the Toyo. I didn’t even want to go that high. So I opted to not consider the ko3. Luckily I have a set of te37xt Ray wheels 17lbs per wheel so it helps with some of the lbs per corner.

 

The reduced profile on the scalloping (raised sideways) is to save weight. The ATII had an “extreme” version which were an E rated tire with raised scalloping.
Also, I’m wondering has anyone looked into what part of the globe these premature tires are wearing? My guess is the heat affects the soft composition more. As in Canada just to the North of me, I use the SL and am going on 24k on mine with no issues. I like the angled siping for cornering in the wet and they are still very surefooted tires even in the snow. Whoever is running 5 psi over on them should look into dropping them down to 31 cold. A lot better ride for minimal wear differences says win to me. This winter will be my test of if I need new ones next year but my guesstimate says not yet. So far they have been really good tires for my driving style and another tire will have to really grab my attention if I was to consider changing. They’re good all around comfortable tires. They just don’t last as long as a KO2.

 

Technically, the one size larger than stock SLs (such as 265/75R16 and 265/70R17) should actually be at 27 and 28 psi respectively. Even those PSI levels carry way more than the weight of the truck.

The stock OR size comes in a true P metric of P265/70R16 111T for the Toyos, and is different than the actual stock size of 265/70R16 112T. As such, the P265/70R16 should be ran at 27 psi as well as opposed to the stock 30 psi. I continue to see people technically over inflated, and that certainly doesn't help the wear, although it probably doesn't hurt it dramatically.

 

@BLtheP did you see any consensus or recommendations on what to run the 285 in C at psi wise? I should have them on the truck tomorrow.

 

Calculator says 35, but that's because LT metrics are not rated below 35. 35 on those tires is significantly over the carrying capacity of the stock tires at 30 psi. This tire gains about 42 lbs of load per psi, so I scaled it down and it matches the stock load at about 31 psi.

So I would go with 31 if it were mine.

 

@BLtheP very cool thanks I’ll give that a shot. Just picked them up and luckily all is well. There’s definitely a difference in the size of the side wall lugs. P almost non existent and flush to the tire. These Lt’s 285 has a lil pronounced rubber protruding off of them. It’s not an insane amount but there’s 100% a difference and due to the design you can notice it. The Lt’s look better. For me it was enough of a visual difference that I didn’t hesitate to exchange them. Can’t wait to get them on. Will post pics by the end of the week.

 

AZ on my last set and I'm sure they melted. The new set is wearing a little better in the front thanks to a fresh alignment, but still wearing faster than I'd like. Overall a nice tire, but I think I'll try something else next time or at least a C or LT size.

 

I really wish they’d just offer a C or D in the stock size like KO3 will have. Sadly they offer very little in the stock size.

 

That’s why I bought 17’s. I had no problems w the OR wheels except the lack of variety on tires so I went a size up

 

I’d love to see 285/295 70 18s in something lower than an E — Falken has one but is heavier than their E load for some bizarre reason — I hope more tire companies come up with some lower load larger tires for us

 

285/17/70 C load 55lbs.

was torn between these and the RT Trails SL at 49lbs. Overall the at3 seemed like an overall better on road tire and I just felt like the tire went seamlessly w my ray wheels more so than the trails. They are a clean looking tire.

I was at about 17mpg w Nitto Ridgegrappler SL 48lbs with my Cali raised off road step sliders on; about 150lbs.

now wo the sliders on (they need to be refinished) and the new tires I’m still at 17mpg local and on the highway. If I put the sliders back on I’m guessing I’ll lose a mpg. Not that bad at all.

the tires are Smooth and quiet imo. Way better than the ridgegrapplers. It’s not even comparable. Had them on the highway the noise was nothing at all. The grapplers had a loud hum on the highway and the drone of them was annoying.

extremely happy with them so far, the truck drives great. Keeping them.

there was a distinct difference between the look of the SL and LT C load. The sidewall lugs on the SL were non existent, completely flat to the sidewall. The LT tire has some rubber to the sidewall. It’s not an insane amount but the design of the tire just the extra bit of rubber makes a distinctive difference in the overall look and aggressive appearance of the tire. Definitely glad I exchanged the the SL for the C. Was worth the added weight for me.

 

This is helpful. I was running Falkens on my 2022 TRD PRO and they were incredible in wet weather but a little stiff. I’ve got a 4G now and the lightest 285/70/18s I can find are the Toyos at 57lb in E load—not bad. Only concern is wet traction. They check every other box. I heard they are made in Japan and balance beautifully and are comfy to ride and and have good steering response.

 

Hey, glad it helped. Yea I spoke to the Toyo rep directly. They stated to use only the Toyo site for accuracy to confirm weight of the tire. Surprisingly the weight of the C and E in 285/70/17 was the same at 55lbs. I chose the C because my off roading is minimal and I wanted a nicer ride. Heck I was fine with the SL but the look of them were Mehh and nothing like the LT C and E which are the same. The rep confirmed there is a difference in the sidewall appearance and lugs between the SL, the C+E, and then the Floatation tires. All are different. I have head the wildpeaks are a much better tire in the rain than the at3. I’ve heard mixed reviews on the wet handling for the at3. I simply hate the look of the wildpeaks. I couldn’t buy em. I haven’t had the at3s in the rain but like I said coming from a hybrid tire like the grappler these in C even heavier drive Great imho. Smooth quite great handling so far.

 

gotcha. Yeah I use the website for info only. I’m stuck in E load otherwise I’d get C for sure if it was offered in the size I want. I guess the sidewall is better on the E but I prefer the softer ride. With my 18” wheels versus the 16” I had before I’m kind of forced into E. I wonder how much firmer they are than C? Let me know how the wet traction is when you see some rain!

also it’s funny bc I love how the falkens look lol - side biters are cool .. but it’s subjective … I won’t get them in this bigger size bc they are nearly 70lb

 

@TacoRancher Yes definitely subjective. I’m the outlier on the falkens. Sidewall on the C and E LTs are the same. Can’t say about the difference in ride between c and e. I just played it safe and they were offered in my size so it was an easy choice.

 

So I have the 265/70/17 and have run them for the summer so far. Initial impressions were good, they are quiet and grip well in rain but there's a few downsides for me. First, I am coming from a set of General Grabber ATx (C load) in the same size and I was disappointed a bit that the rock guards aren't as pronounced in the Toyo. I liked the more aggressive look but admittedly haven't really been extreme enough to need the extra sidewall protection. Second, my experiences with the dirt fire service roads of the U.P. were a bit of a shock. These tires slide at the moderate speeds I'm used to. The Generals had way more grip on the loose surfaces. I'm honestly surprised by this. I was expecting there could be a change since I've biased towards a bit more pavement tire but still. Oh well, I need to run 4hi anyway according to the manual just to keep things moving in there.

 

There was a comment made in this thread, i wasn’t able to confirm it but the poster was 100% confident that not only is there a difference in the aggressiveness of the
Side lugs

‘SL non existent, C and E aggressive, Floatation diff from c and e but even more aggressive. I’ve visually confirmed this and spoke to a Toyo rep who also confirmed it.’

The guy commenting also stated that the above is true but that ALL of the smaller AT3 sizes had a more timid SL sidewall, regardless of the load rating C or E. My C rated 285 isn’t insanely aggressive, it’s a symmetrical clean look but it still looks badass imho.
