You can see that a few of the entire side lugs are starting to peel off

I see a significant bias to right-hand turns, the knob you're pulling looks nothing like the knob on the other shoulder. I favor one turning direction slightly because of my foot-forward preference, but I actually am not sure I've ever seen a disparity in left and right shoulder knobs like you have on both tires.

There is heavy center knob wear relative to the shoulders, and little wear on the braking edges. My father-in-law does this to his tires because he rides primarily paths on a Levo SL1 and doesn't lean aggressively on dirt or paved. I'm switching him to T5 compound specialized xc tires.

350ish miles of the Wasatch Front. Lots of loose, sharp rocks (shale) and gravel. Ebike. Magic Mary & Albert Radials.  Make of this what you will.

That rear wear certainly looks like you've been riding over sharpness. I never had a problem either with MM US on the front of my EMTB, rear is a different story like we've seen from many people here. I've been very happy with how well the new Eddy Current has been holding up in SoCal conditions and it performs well too. It's no TC but I have double the miles on the EC and very little wear. I think anyone on an EMTB should give the radial EC a try.

This is how Schwalbe tires die. Maxxis wouldn't fully rip off as often, but would be hanging by a thread. In my PNW experience, old-version MaxxTerrra 3C wore out well before the Schwalbe side knobs left the chat. I personally define worn out as notably worse cornering. So good job, you actually ride your bike hard. People freak out about a Schwalbe side knob tearing, but happily ride Maxxis side knobs fully undercut with no support - it's interesting psychology.

Let's see how the new MaxxTerra compound does. From reports I'm guessing I'll personally get same mileage from them as Schwalbe Soft out back.

I see the same wear pattern across my ebike & trail bike running identical compound tires, it's just massively accelerated on the ebike.  The ebike's only like 10-15 lbs heavier than an enduro bike so not significant when you look at overall system weight (rider + bike).  I always see more pronounced wear on one side's side knobs (right in my case) because of my cornering bias.

I've never gotten to the point of tearing Schwalbe side knobs off because the center tread leaves the chat well before that.  I have gotten to that point on Conti Super Soft though, especially up front (that develops a horizontal crack at the base through the shell rubber, and then the knob loses all stability).  I've got a year+ old Kryptotal Rear Enduro Soft that looks better than a month old TC Trail Soft.  I still need to try the new formula MaxxTerra.

That's interesting and makes perfect sense to me. When I ride machine built jump trails, I typically want to air up from my tire pressure for natural trails, otherwise I roll tires on berms and especially on hips where I'm turning off a lip. This effect is both slow and feels sketchy as hell, and when I pump up my tires I feel like I can pump more efficiently and put weight into the bike in more places.

Radials have less casing stability, which is their selling point but also their weakness, so I can imagine them being less stable on machine built jump trails (or any high G-force jump), worse for pumping, and potentially shedding speed.

What I've been doing with them is absolutely airing the shtt outta em BMX style, and for me personally it's been a game changer for riding in general. Especially when you can air the tire back down on a tech trail and then you get back into that radial casing feel so it almost feels like having a different tire on. It's like... Shock tuning. In that, it works in both settings for DIFFERENT reasons. Whereas with most other tires I feel there is a quite narrow range of acceptable psi. Mostly in that airing up too much makes it completely worthless for traction.

Ran Alberts front and rear for my previous bike, basically all I do is hard pack jumps so it worked a treat.

Going to throw Romys on the new bike. Just for science...

I know some people have not agreed with the narrative, but I believe radials are specifically for people who want to run high psi tires, NOT for people who want more traction out of the same psi feel in terms of general riding in a straight line, compliance, etc. I think the vast majority of industry tires have already proven to have excellent traction at the 'correct' psi.

In my experience none of them have quite displayed exceptional traction while aired above their optimal psi. The Schwalbe Radials have retained cornering ability while offering the straight line support of a higher psi. Optimal for heavier riders, or riders who love to take dogshtt lines in technical chunk (hey, those BOTH describe me!)

I feel like the hot take is radials are good for low profile tires, alberts romys and maybe something else. They may not feel great with tall knob tires where you're stacking vagueness on top of vagueness, even when you are in the absolute slop and need mud spikes. Not like I have experience, but only saying that because I THOUGHT they would be game changers for slop, and some dudes I talked to online said not really. Just made an already vague riding experience even MORE vague. And I couldn't quite disagree with their logic. Take their word for it, at least.

And stuff with tall knobs like the Mary, with the more compliant chasing feels more precise and less vague overall than the same tyre with the regular casing

On natural wet or dry, off camber, wet or dry, I find them superior to regular casing 

I'm curious what pressures and casing you're running? I swapped from DH MM radials to an albert/romy trail pairing to try and lighten up my trail bike and have some faster rolling for summer.  I've been having a hell of a time trying to get the pressures nailed. So far I am leaning back to the idea that trail casing just might not be for me.

If it helps, I don't find that I have to run excessively high pressures (I'm 170 lbs). For PNW summer riding I'm a few PSI above what I would run on standard casing tires (i.e. EXO+)

Tacky chan radial front (trail): 24 PSI

Romy radial rear (trail): 28 PSI

I wasn't a fan of the Albert on either end of the bike.

Word. I’m running fairly similar but pressures to you at the moment in a similar environment. I’m about 160lbs kitted. Im 25 Albert and 27 Romy right now.
