35s on my gladiator, traded in at 16k miles, so probably 12-13k on tires. No complaints, but not a lot of wheeling in the gladiator. Ran these at 27-28 psi on the road, 15-20 on the trail.

So, with 18k on the clock, and about 17k on my Milestar Patagonias, I had a critical sidewall split and needed a whole new set. The Milestars had about 8/32 left of tread left on them at this point. I wheel rock trails about once every month to two months, so for me this is atrocious wear. For the price of tires, for them to last about 2 oil changes' worth is unacceptable. Further, while I was initially pleased with the loudness of the tire, they grew horribly irritating as they wore down. Mind you- they wore down FAST. The milestars are meant to be run a little more inflated, to stay on the center treads. However, inevitably you start having the outer blocks contact the pavement, which creates a din on the freeway. Not mud bogger levels, but enough to notice and be annoyed. For me, the most irritating thing of all was 2-5mph vibration through the cabin, which rattled every bit of plastic trim. At first I associated it with a cool MT experience, but it quickly became annoying. The visor, upper dash trim, car seats-- it all vibrated intensely.

I also have a long standing MPG of 16.7 on these with 4.88 and 4.10 gears-- re-gearing had no impact on MPG.

I will say these tires, when I've used them offroad, were spectacular. Incredible grip, and up until they split, I had no complaints. I can't say that any tire would've fared better in regards to the split, so I can't hold it against the tire without more evidence another tire would've been fine where this failed. But the negatives outweighed the offroad ability, and on I went. See for yourself in the pictures below and tell me if this looks like a tire with 17k miles, or a tire with 40k miles....

They measure at 36" exactly mounted and aired up to 35psi. My initial impressions are that I'm pleased with the on road manners and noise. The sidewall looks very cool compared to other ATs. It's as silent as a road tire, and no MT low speed vibration coming from the tread blocks. I am hoping they soften as they wear, because I have a bit of a "princess and the pea" sensation of feeling a lot more of the road imperfections. They look awesome, and for all the daily driving I do, I'm already happier. I expect they will outperform the patagonias in the soft sand of Johnson Valley, but the real question is how these will hook up on rock trails. And, I'm curious to see the long term increase in MPG, if any.

I will thank @Discount Tire for price matching the 4wp discount and getting everything set up. I went with them for the warranty in case I have another premature sidewall failure. Even though I get wholesale tire prices at some places, the discount didn't offset the value I see in the warranty.
I’m going off the type of tire chunking that I am seeing on your cut tire.

what psi off road did you run? And how much tire spin up shale/rocky roads were you doing?
I agree with most of your post…. They are phenomenal when rock crawling…. But I don’t think I would ever daily a set of these again.

For comparison I ran 35~psi on road. Off road light use 18psi, crawling 12, and snow 6.
For speculation/experience with 3 sets I would guess your tire pressure was 22-24? (If I’m wrong I’m wrong….) just going off the type of chunking in your photo.


Baja boss mt’s hold up really well in the stretch between big bear all the way up north to the white mountains….
Just be warned I have never made it through trails up in the whites without destroying at least one tire- I swear it’s cursed up there…. More specifically papoose flats…. Saw the plates and terrain….

PSI offroad, usually 20 psi. Almost all of my offroading is rock-crawling. Some shale in sections, but mostly hard, unmoving rock. Again, I'll say these did very well on rocks. I tend not to drop below 20 as I don't like the risk of losing a bead.

I definitely understand the thought and pain with resetting on the trail…. Regularly ran at 12psi on an 8.5” wide wheel and did not bust a bead…. It’s weird…. Patagonias defy a lot of “normal” thoughts with tires.
lower psi in my opinion could have saved some life.. (for anyone else reading/running them) ?

My exp with the milestars. They have to be at 35-37psi cold or they seem to feather and melt. At that pressure they ride rough and we have to air down for even fire roads or its absolutely terrible riding.

Mine might make it 20k but they will be worn out. Next set is going to be 40" of anything other than the milestar's.

If you air them down to 8 or so they are incredible offroad!

They cost about half what a real set of tires would but they melt as you drive!

Thanks to all for sharing.
FYI. Am looking to get new tires for my mod (4.5” MetalCloak Game Changer, winch, full skid plates, Truss and Gussets, Re-gear to 4.88, etc).

Interesting that if the cost is so low, might work out perfect in my case.
I’ll start out with the Patagonia 38” tires for now. And then in 3 to 5 years when they wear out, I’ll switch to 40” tires

I run mine 29 psi. Calculator says 27 but i like a little stiffness. 35 must be a damn brick. Calculator for my set with 35s is 29 psi. I run 33 on those.

dude the contrast of the mud against the black paint is so fucking cool. My brain initial thought said 2 tone for a hot sec.

My gladiator sits most of the time, so I don't want too big a flat spot when I get in and drive. It used to be my DD, but now its a tow/wheel pig and spends most of the time in the driveway.

I like the Baja Bosses. Thanks for the review. When my 37" Falken Widpeak AT3Ws wear out I plan on getting a set of Mickey Thompsons Baja Boss AT in the same size. I've ran the Falkens on the last 3 Jeeps and love them. Most of my driving is on road though as a DD.
