from toyo site it looks P285/70/17 is 46 lbs and the LT285/70/17 Load C is 55 lbs. Curiously, the LT285/70/17 load E is 53 lbs, how could it be lighter than the C? I'm also curious of the MPG and range impact.

In regards to LT-E being lighter that LT-C...

Load carrying ability and tire capability/durability are somewhat separate things today versus the past ply days. Previously, load/pressure abilities and durability were tied together in that they added literal more plys. Which intuitively weigh more.

Today plys are notional. More load capability is achieved through a combination of higher tensile plys, tighter threads per inch, or larger gauge nylon and steel belts to increase the air pressure capability. Not necessarily more material. Load capacity is also about the heat envelop of the tire, where more material/mass can actually decrease load capacity as heat generated when the rubber and material distort going round and round.

So it's wholly possible that a lower load rating LT-C in the case, has just as much or more rubber/material than a higher load rated tire. So it's not necessarily true that the LT-C may give up durability or puncture resistance than an LT-E tire as it can have as much or more rubber and material.

What is the weight difference b/w old P-metric vs. new LTC? Do you feel the small bumps etc?
Others covered the weight difference so not much point addressing it.

I do feel a notable difference in ride quality on sharp bumps but I attribute that to the increased tire pressure. Minimum 40psi for these, I ran the p-metrics at 32 in town.
 
One of these days I will go to Hidden Falls Adventure Park here in Austin and torture test my P 285/70/17s in a "safe" environment and report back.
 
Anyone have any thoughts on the trade offs between 275 70 18 (33.2”) and 285 65 18 (32.6”)? I am running a 2” Dobinsons MRA lift.
It looks like the 285 has no rubbing for stock. I would prefer to do the 275 but might need spacers.. the 275 width really makes the truck look anorexic lol.

Based on my research on this forum, I’m leaning towards 285 because…
  • 275 70 18 might require spacers, and the custom built Bora spacers are quite snug..I’ve read people need a crow bar to get the wheel off. That’s not ideal if dealing with a tire change on or off road
  • Even with the spacer, there appears to be rubbing.
If you’re running 275 without rub please chime in and tell me your secrets!

I am running the AT3 in 275 65 18 SL but wanted to go up to something more dependable in the future for more challenging backcountry terrain

I have 275/70 18s on stock rims with no lift. No rubbing.
 
One additional Q is that Toyo’s 285 65 18 tires recommended rim width of 8.5” is out of spec for the Heritage rims (8”) not sure if that’s been brought up here or not.. didn’t see it in the last few pages and see a few folks running it. If you’re running this size on Heritage rims, wondering what makes you feel comfortable? I don’t know enough either way so genuinely curious

The stock wheel is 8” wide too. Dozens of folks run that size tire without issue.
 
Can you share pics?
Not a new pic, but here's one from the day I put them on.

I see you have the Falken Wildpeak AT3Ws on your hundy. I ran the Wildpeaks on my last 200 and really liked them. I thought their snow performance was markedly better than the BFG All Terrain KO2s but noticeably worse than the Goodyear Duratrac. I think the Duratrac is a pretty crap tire in virtually all regards EXCEPT snow performance so I felt like the Falken Wildpeak AT3W was the best all around tire I had found so far. Curious to see how you think they compare, especially in the snow?

I would give the edge to the Toyos in the snow. Really like both tires, but the weight of the Wildpeaks vs the Toyos and the fact that Wildpeaks cost as much as anything else these days led me to try out the Toyos. Really glad I did.

Awesome, been wanting to try them out but have not found many people who could speak to both tires in the snow, appreciate the feedback!

Sleuthing the interwebs, here's some candid info I found from a professional tire tester that benched these tires in controlled conditions. Consistent with your and @Chewbacca 's impressions.

@Icutmetal Great options for sure! OK, as for the ATX General, I actually started testing that tire for General after I finished development on the X3 MT. During my testing of the ATX, they pulled me off the project since my main General contact had transferred to Germany, so I never finished and haven't tested the final product. I do remember that they were pretty good up until that point. As for the K02 , Toyo AT3 and Falken AT3W go, from what you plan to do with it I would not go BFG. They were not ideal in the snow and the ride comfort was really firm! Controlability was also an issue .... The Falken AT3W is a fantastic tire and one of my all time favorites, but snow performance was below the new Toyo AT3. I might go with the Falken 1st but it sounds like you want low road noise and good snow performance so it looks like the Toyo did better after checking my data that I am looking at for you in those specific areas....both great choices!

Also having had the Falken's prior and the Toyo's now, I wouldn't knock the weight as a disadvantage for the Falken's. The Falkens outright give you more: more tread depth, more aggressive side lugs, rim protector, where as the Toyo's are less aggressive in these features without any rim lip protectors.

I find it funny how often parroted that KO2s are better because of weight...well they consistently measure significantly smaller and slighter versus the big full featured Falken.

I have a set of 4 AT3 285/65-18 with 4000 miles on them that I am taking off Monday. Going one size bigger.

If anyone is semi local to Mississippi and wants a good deal on these PM me.

Hah, I was wondering why you went so conservative on tire size in your build thread. Glad to see you're going bigger.

During the great TX freeze, I was the ONLY one that could get down and back the Hills with snow and ice sheet sandwiched roads where I live.
The AT3s blew me away in both fresh, wet and slick compacted snow uphill and downhill.
I sincerely don't know why people are still buying the KO2s in the quantities they are other than the looks and availability due to ubiquitousness.
Gotta admit, the sidewall pattern is perfect. Somehow both busy and neat at the same time.
 
I've run p metric Falkens on all 5 of my Toyotas, and just replaced a set of Falkens on my 200 with the p metric Toyos.

The Toyos are louder, and ride a bit rougher. I was able to get a killer deal, and they have been decent so far. We'll see how winter performance is later this year. Mileage has been about the same.

So far I'd say I like the Falken's better based on early impressions based on noise and ride.
