45 lb KO2s in 265 are LT C load. There is no SL KO2.

Wildpeaks are a heavy tire compared to others of same size and comparable load rating.

Are there any issues with the AT3s in 265/70r17 p-rated on forest service type roads. I’m wanting to try them or the Michelin Defender LTX M/S because of the weight. I do alot of highway driving, but drive on forest service type roads when I get to my hunting area.

I currently have BFG KO2s and love them. Just wanting to try a lighter tire to try to save on gas.

They should be fine. I am located in the midst of state and national forests and live on hilly, rough gravel roads. I had the P-rated AT3s installed in February and love 'em.

You'll probably be fine with just the Michelins on FSRs. Lots of reviews of them on the expedition/overland forums and are really good in most conditions.

Toyo set going on Black Friday sale this Thr-Sat at Discount Tire. $110 off a set. Also rumors of ~$100 rebate starting then too:

Discount Tire | Tires and Wheels for Sale | Online & In-Person

275/70/17 set will be $1224 - $110 + applicable tax/install fees.

I picked these up a couple months ago.
Now mine are Limited 20 rims, but I was in Erie during the recent snow event, and they also got a test in wet leaves and mud archery hunting and I'm pretty happy with the AT3's. Only a couple thousand miles on them, but noise has not been an issue and they've done well in heavy ponding as well. They also look far better than most Ltd tire options. FWIW.

So if toyo E rated weighs less than most other brands E rated or say wildpeak... wouldnt it be softer- my P rated wildpeaks are 47lb each, toyo e rated are 50lb... which is very marginal

An LT construction is very different from an SL construction regardless of weight. Brand quality generally shows in the weight. Falken being heavy is arguably due to being lower tech.

As for forest service roads:

I got a puncture on a Mickey Thompson ATZ P3 on a forest service road from a very large nail. The tire did last me the 400 miles from Utah to home so there is that.

The ATZ P3 and its successor Boss and sibling the Cooper MAXX are the strongest AT in existence, arguably a tad stronger than the Ko2. But big nails and bad luck can defeat ANY tire.

So it is pointless to go heavy duty just to drive forest roads. The kind of thing that will damage a P metric on a forest road can also damage any tire.

The place where the strongest tires are needed is the desert. I have done plenty of 4x4 trails on P metric. Mountain has never been an issue. But the desert is another story.

While 'forest roads' where you are may just be gravel or dirt, around here they have lots of slate and shale and p-rated tires just do not hold up long term like LT's do. Can it damage LT's? Sure but less likely.

Also, I'd like the source regarding the 'strongest' AT inexistence. I'd like to know the basis of that claim (I'm an engineer so I can nerd out on that kind of thing easily).

If you have followed me on this forum for any amount of time, you will know that I have close to 500 trail runs, so take what I say or leave it. Also, it is clearly stated that I live in Arizona, so I am not sure you want to raise doubts about the credentials of the terrain here

Good question about the strongest tires. I am not going to dig back into old Excel sheets, but you will want to dig various Cooper and BFG materials on the internet.
You will want to look at thread plies, on the one hand, and sidewall, on the other hand.

You will quickly find out that the Coopers/MT and the KO2 stand above the other ATs. Between those two, from what I recall, the Coopers used marginally thicker plies, which is why I said "arguably."

You will also find out that good info about tire details is very hard to come by, you will need to piece things together from bits and pieces.

Various "professional" reviews and the like are worthless as they only talk generalities.

For load capacities, you can dig a Toyo load table which is very useful to determine actual numbers vs generally assumed numbers. That's a different topic but one that has caused many inconclusive tire threads on various forums.

Cheers and Happy 2023.

looks nice

Agree, NICE

I know your post is old and I'm resurrecting an old thread but we're moving to TN next year and I just picked up a '21 ORP which I will be putting a slight lift on and will do wheels and tires at the same time. I'm going crazy trying to figure out which tires to get. I was set on the Wildpeaks then I started seeing these Toyos might be better. Then, I see your post and now I'm really confused, as exactly what you said about rain and mud in TN was in the back of my mind. I want to get the right tire before we move. What did you end up deciding on and how is it working out for you? Thanks!
