New Toyo Open Country A/T III tire

Looks like there is now a load C LT265/70R17 coming. It has a part number on Toyo’s website, but is not listed at @Discount Tire or TireRack or anywhere else.

Wish I had known this, I’d rather a LT265/70R17C over the LT255/75R17C I went with. I chose them because I wanted C load over SL or LT E 265/70s.

 

Just learning about this now, and starting to get a bit confused between all the load ratings.

LT (meaning E-rated?) and C have 16/32” of tread depth. SL has 13/32”. In terms of load carrying capacity, C < SL < E.

Am I right in interpreting that basically, tires with 16/32 of tread depth have less siping and shallower siping than those with 13/32?

 

You have it mostly correct. LT basically describes a heavier duty category of tire. Inside the LT designation you have different sidewall ply ratings: B (4), C (6), D (8), E (10), F (12). They carry the same capacity at the same pressure, but the difference is they max out at the pressure they can carry maximum load at. For example, a C tire carries its maximum load at 50 psi. You can put more pressure than that but it will only carry it’s rated max capacity at 50 and won’t have more capacity with more pressure. E, on the other hand will carry the same load at 50 as C, but can go up to 85 psi for more load capacity.

While C and E are both LT and will both carry the same load for the intent of a Tacoma, the E will ride stiffer due to the thicker sidewall. Both will need to be inflated to the same pressure to carry the proper load.

Non-LT consists of a couple categories: P-metric and euro-metric. P metric have a P in front, euro-metric don’t.

As far as the Toyos and most other tires are concerned, LT have 16/32 tread and less sipes (both quantity and depth as you said), and the non-LT (both P and Euro) have thinner tread depth @ 13/32.

for this specific example, I want a LT C, instead of a SL or a LT E. Which is why I chose LT255/75R17C. I wanted LT265/70R17C, but it wasn’t available. It was only available as an LT E or an SL. Now it’s coming out with the C option. The benefit to that is thicker sidewall, deeper tread (less sipes and depth still though), but it weighs less and doesn’t rise harsh like an E.

Hope that helps and doesn’t make it more confusing lol.

 

That certainly helps a lot! Thanks. That siping thing does put a small wrench in my plans…but I feel like the AT3s are probably going to still be my pick for 255/80r17 or 255/75r17 all-terrains that are 3pmsf rated.

 

I was a little concerned about going LT due to the sipes because I drive in a lot of wet weather and I really need to be able to brake without immediately skidding. So far they’ve been fine. I believe the sipes start disappearing once you’re down to around 6-7/32s. I think with our trucks being lightweight, it will take a long time to reach that point. So far so good.

I am overly cautious in the rain though, because I have past trauma from nearly wrecking my Jeep multiple times when my Duratracs would immediately slide in the rain.

I will say my XL 265/65 Toyos were very good and never slid. Based on the amount my MPG has dropped, going SL for 265/70 wouldn’t have been a bad choice for me. But oh well. I like what i got.

 

I'm wondering if that new 265/70/17 in C load on Toyo's website is off, in terms of listed weight. Seems odd the C would be heavier than the E in the same size.

 

Yeah, doesn’t seem correct. The OWL and BSW are different but still, the E BSW is only 49 lbs so the C seems high. I imagine it’s just incorrect.

 

Mounted up a set of 35x11.5r17 on my truck. Love them so far!

 

Just be forewarned, these are the narrowest 255s ever. Dont mount them on anything bigger than a 7.5” wheel.

 

So, I wrote to Toyo to confirm these numbers. Their reply was, "The OPAT 3 LT265/70R17 C/6 tire weight is 50 lbs. and the LT265/70R17 121/118S E/10 tire weight is 48 lbs." So they're confirming that, counterintuitively, the load C is 2lbs heavier than the load E.
I also asked them if they had any intention of producing a 255/85/16 version of the tire. They said they would pass it along to the product dev group for possible consideration in the future. For whatever that is worth.

 

If I had to guess, the LT E is probably heavier than they say it is. 265/70/17 C makes sense being 50 lbs, as 255/75R17 C is 49 lbs and the wider 265 should add some weight due to being wider and not much taller. The E 265/70 being 48 lbs makes no sense when compared to either of the other two. But who knows. I have a suspicion that when you asked, they just read you the specs off the website, much like you already looked at.

 

Yeah, that could certainly be the case. Maybe we could ask if Discount Tire would be kind enough to throw one on the scale?

 

They might actually need to be informed of it - it’s not on their site as of the last time I checked. But that is a good idea! Maybe they can weigh both.

 

You mentioned you wish you had gone with the 265/70 over the 255/75. Can I ask why this is the case? I assume you mainly wanted the C load? I've been considering both sizes too. You get a slight height bump with the 255, though it's pretty minor of course.

 

I said it at first, mostly because 265/70 was what I wanted all along but didn’t buy because I really wanted LT and Toyo. After a few weeks, I like my tires plenty fine. The speedometer was one factor, 265/70 reads accurate while 255/75 reads 1-2 mpg slow, but it’s very minor. I have no complaints with 255/75 at this point, looks good, handles good. I did like that with my regear, the extra half inch brought my highway rpm down just a tiny bit extra without hurting performance anywhere else.

if I had to choose between 265/70 C and 255/75 C both Toyos today, I’m not sure which way I’d go honestly. The mileage would be the same on either.

 

Anyone rolling on this size yet? I’m in a 3rd gen 4runner but these look pretty sweet as they measure 33.5/10.5 un mounted and are a D load at 54lbs . Good option for someone who wants a skinny but tall 33+ without having to run the E load of the 255/85 market. Plus I prefer a taller tire without all the extra width

 

Following, considering this size for my next set.

 

@Ogreboi666 strangely that tire size is available in both the Toyo A/T3 and BFGoodrich KO2. Stock is available for order.

 

Toyos are 150 less each tire! Are there any toyo sales coming up this fall?

 

@Ogreboi666 unfortunately our sales promotions update each month so we have no way of knowing that far in advance, but rest assured, we honor our Low Price Promise on any product we sell and if a competitor has a better price, we would adjust accordingly.
