This is what's right with The Industry®

i had been running a minion SS EXO in the rear. nice tire, but i'm just too heavy for an exo casing. i got a puncture in the tread of it (which did seal) but i always felt like they were low even when i knew the pressure was right. i'd been running the wild rock'r in the front, and had another one so i swapped out the minion SS from the rear. the biggest difference i notice is the casing.
I'm 240 at the moment, running 25 psi in the rear... but with a DH casing and Cushcore over a EX 511.
what size tire? i should note that the tires i'm running ~30psi in are 2.35"
had you run them previously without cushcore?
I was on EXO sidewalls before (because 27.5" + has no other options) and was ripping and tearing them. Destroyed a rim as well on a hard rock strike. Went straight from that setup to 29", DH casing + Cushcore.
215 without gear.
i25 internal.
Front 27.5 Assguy @ 25psi
Rear 26 DHR2 @ 28psi
DH casing, no insert.

feckin' 'ell mate! that's not a wheel, that's a boat anchor!
what bike are you running this on?!
an e-bike, because you're gonna need a motor to pedal such a heavy damn wheel uphill
My uncalibrated finger calipers think Rock'r 2's casing is a bit thicker than the EXO.
I agree, the casing makes noticeable differences in feel. I was amazed the first time I used a 2-ply tire - made the back end feel calm, with everything else being equal. But it sure felt draggy climbing during the first few rides, not so much because of weight but like extra damping dissipating a bit more of pedaling force. After cutting 5 single-ply tires prematurely in 3 months last year and walking a few miles off the trail a couple times, I decided it's a worth-while trade off for me.
This is not untrue. E-bikes let me run the tires and rims that I'd run for the downhill part of the ride without suffering with them otherwise.
I’ve been running dh casing and cushcore on a DT fr570 this year on 2 rear wheels with 25-30 psi. Both rims are pretty much done but it was nice getting only a few flats and no wheel truing. I normally run 471, 481 or 511 in the front without an insert.
On most of the dented rims I have seen, the dent is toward the inside of the rim. I wonder if this is due to the fact that the rim is weaker against purely vertical impacts in that direction or if this is due to the fact that the impact direction in reality is slightly angled (I.e. the bike is leaned/tilted on one side when the impact take place). It is probably a bit of both...I agree, can't stop the want. What's up with that? Have it in my head 2.5mm wider each side is making the rim bed collapse more than it should.Should just add air eh.
Anyhow, I find quite interesting that Newmen is making rims with angled side walls:
Compare to straight walls from DT
Newmen claims that their rims are less prone to dent because of that. I have one on the front on my XC bike but that doesn't mean much....
Maybe somebody here has some experience with them?
This model should be DH worthy https://www.newmen-components.de/en/79/mtb/rims/evolution-sl-eg30/
Rims are wider and the beady bit is shallower so rocks have a lot more of a chance of contacting the centre of the rim.
I ran hookless rims for a short while and I just found that they sliced tires open, newer ones seem to have beefed up the bead area and have more of a radius as above so they are probably fine.....
If you are worried about dinging the centre of the rim you might want a different rim construction.

I suggested this maybe a year ago, the vertical rim walls are an obsolete heritage from road bikes. We have had tires balooning out of the rim profile since the beginning of our sport, and the scarce lateral support we got from narrow rims is today still a joke. The industry™ is still trying to sell us we don't need bead hooks, trying to unload all the burden on the tire beads, but I think if we could get moar bubbly/inclined rim walls with better hooking on the tire bead we would enjoy more rigid rims, better tire support and a lighter weight overall.
I can't seem to find my post about this, if I do I'll add it here.

I decided to test this theory. I bought a pair of Chromag Phase 30 rims. They have the angled sidewalls too. I'm planning to lace them up over the winter.
Been running Rimpact for a few months. I think it's comparable to Huck or the new lighter weight Cush Core - which I fondled a few days ago, and based on the eyeball and squish test, it seems about as adequate as Huck.
I've been happy with it. It does get chewed up, but handles it better than Huck. Better coverage and more damp than Huck, and doesn't slide around. I'm stubbornly sticking with EXO, and I'm running into the low 30s in the rear cause I'm sick of pinch flats. Ultimately, I think Rimpact with a DD casing is probably the ideal rear trail bike tire scenario for me as far as feel, weight, and protection.

for the price i ordered a set. i'm probably just gonna install it in the rear. we'll see.
I'd argue that you need all that impact protection because your 50something pound bike bashes wheels into rocks harder than my 31lb bike.
This is true. But there's way more variation in rider weight than bike weight, fwiw.
Interesting..
And their beefy sucker: Chromag BA30 rim
Is this the pink unicorn I've been looking for?
Yeah perhaps. No one ever wants undue stress applied to their nipples.Interesting..

That lace stagger is stupid and removes bracing angle.
They should have sunk the spoke bed channel and crossed the spokes, increacing bracing angle
I don't know, we still need a tight fit between the tire and the rim to be able to ride tubeless and avoid burping. The hook is now moved inside the bead on some rims as I see it and as you can see on the newmen profile I posted above
Surprised you need anything inside wild rockrs. Those were the most reliable tires I’ve ever run even for lift days. They eventually bled sealant thru the sidewall but never made me walk.
I think we are seeing more dented rims because rims have gotten wider. On a narrow rim the sidewall is under the center knobs and therefore protected. On wider rims the channel between the side knobs and the middle thread of the tire is usually exactly where the sidewall of the rim is, so not much rubber to protect it from denting.
How much do you weigh
230
What pressure did you run in them
