New power wagon owner. Am thinking about swapping out the OEM tire for BFG T/a KO 3 in LT315/70R17/F 128S size. Will this work with no rubbing and importantly will it fit in the spare tire location? This tire is listed as 34.4 inch diameter.
 
Are they out yet in that size?

To anser the question, yes!

I've been running 35x12.50R17 tires of various brands, including BFG, on my PW since new in June 2021 and have had no issues.
And yes it will fir in the spare. You have to angle it up on thevfront to get it above the track bar as you raise it up. I also did a little trim on the heat shield for clearance.
Details in my build tread.
 
The OEM glass tires must be swapped out ASAP. Those Wrangler Duratrash are frankly DANGEROUS as they pop so easy. I cannot believe they still roll those things out. I plan to drive my next one straight to discount tire and avoid the dozen flat tires of the first round. The BFG HD terrain 35x12.50 is the best tire for this truck, hands down.
 
I have almost 50K miles on my original Duratracs, with the exception of one nail, no problems. I do plan on replacing with either a 35" or 315/75/17 General Grabber ATx on stock rims. Both seem rated identical except for speed index and I never drive over 100 MPH, so.... I guess I'll get whatever is cheaper.
 
Careful when looking at tires.
I've run into the problem where the 35x12.50 tire is not rated for a 2500 truck while a 315/70 is, from the same manufacture. And vice versa.
 
The BFG HD Terrain is designed for Heavy Duty trucks specifically. For towing, off road use and so on and long life. There is a reason why they are getting nothing but 5 star reviews. I also put the same exact tire on our Ineos Grenadier. Also, a heavy duty, solid axle beast.

Firstly, Ineos Grenadier - very neat! Had a friend considering those before he decided he wasn't hardcore enough for the (likely) reality of living in such an offroad-specialized vehicle.

Secondly - a good call, I did some poking around on Tirerack:

In 315/70R17 sizing:
BFG KO2 - load rating C (max 2535lbs/45psi)
BFG KO3 - upped to load rating F (max 3970lbs/80psi) -- the KO3's do show available in that size on Tirerack fwiw
BFG HD Terrain - load rating E (3750lbs/80psi)

Additional important note re the HD Terrain, they are NOT 'Severe Snow' rated according to TR, whereas both the KO2 & KO3 are. I had KO2's on my Titan years ago and they were quite good in the snow. KO3 will likely replace my Duratrac's in another year or two.

This guy again

“A dozen flat tires because they pop so easy”

This is the same guy that says his 6.4L hemi has broken manifold bolts three times already
 
Not sure about the snow rating. My experience has been they are exceptional in the snow. That being said, we only had one bad snow storm so far this year, been dry since. But last spring I did some deep stuff, including 3.5' of snow towing a 7K camper. I never got stuck, just had to go back and forth a few times. I also backed up a snow field as far as I could last summer turning around on a trail and was blown away by what it did. I was very concerned about the hard compound on these. I live in a neighborhood with a big hill, and sometimes unplowed roads so its a good test. Not like where we are moving to in Silverton in a few years, but a good test. So far better then other tires I have used. Really hard, so many variables, so not real scientific. I spent 10 days overlanding to Moab and such with the Ineos October. I would say a BFG A/T might be slightly better on extreme stuff like stacks of vertical ledges, but not by much. To me the longer tread life and puncture resistance is worth it. You cannot go wrong with any BFG off road product, but for heavy duty purposes I believe in these HD Terrains. The other thing I noticed is, I really need a tire rotation right now, but they are resisting cupping better then other tires I tried.

Anyone who wants my 2018 PW for 10K below book because lifters and manifold bolts are a hoax on Hemis I will sell it to you asap and drive something else until Stellantis opens the order books. I would be happy with taking the hit. As far as the Dura tracs, if they are not popping, you have not been off road. I live off road, and have a subdivision business off-grid so I deal with tons of flat tires. But if you think those Dura tracs have even any durability or redeeming qualities, you are not working that truck hard.

I have never heard someone getting 10K, let alone 50K out of those. Guessing no off-road use?

You are the only one i see complaining about this…. They are some of the longest lasting tires for HD trucks. Here were almost exclusively use them for the mines as most other tires get shredded by the gravel and ore, way more chance of getting cut up than your off roading. I usually get 60-65k miles out of a set of duratracs. The mines usually get 30-40k miles and they get abused hard.
 
Duratracs are very good in the snow IMO. The new Duratracs have been improved with a 3 ply sidewall just like the KO2 or KO3 so the weak sidewall has been addressed. Some tires won't be rated for over 50 psi so your air pressure sensors will be on all the time if you get those with the softer ride. I never had a problem with Duratracs but I did switch out to 315 10 ply with a +19 offset wheel as soon as I got the truck. If you get a wheel with the right offset, around +20 you can usually run up to a 37 inch tire but a 35 inch tire is as big as your can get in the spare tire. I just put on the new Goodyear Boulder MT with a 3 ply sidewall in a LRE. Pretty new tire on the market and so far i like them but they are not 3 peak snow rated. The have a deep aggressive tread and don't make too much noise on the highway.

Did you just join the forum to be grumpy in every thread?
 
FWIW, I got 40k out of my stock duratracs (and they probably had another 5-8k left on em). I thought they were decent, except in the rain. I went with BFG AT 35 x 12.5 on stock rims. No rubbing. I still have stock spare.
 
I just put on the BFG K03 and so far so good. They have seen, sand, gravel, mud , and HWY I have no complaints
