The widest 26" rim available
Hello, please share your knowledge on the existence of wide rims in a 26"er. The widest I'm familiar with is the old Araya RM-25. These wider rims are intended for use on a set of winter bike wheels. I want as wide a contact patch with the ground as possible without lowering tire pressure. This is not a fat bike, just a regular old mountain bike. There has been mention of a Snow Cat rim but that is a pricey specialty rim and was hoping for more of an "off the shelf" option. INput welcome!

Also, find out what rims Surly uses on their Lowside 26-plus build.

Sun Rhyno Lite XL’s are pretty wide. I’m not sure of the internal width of your RM-25’s.
You can find them as 26” wheelsets.

You looking for the widest double-wall rim with a brake track? Maybe the Velocity Cliffhanger.
I used a Weinmann AS7X when building up the new front wheel for my Diamondback. It was decently wide (25mm inner) without being unduly heavy or expensive.

Sorry, should have been more specific with the bike and rim requirement. The intended find is a rim brake type, double walled, non-fat bike, 36 spokes. It's going on an old steel frame hardtail mountain bike with canti-levers.

I used to seek out the very wide (30mm?) Mavic Module-6 rims in 26", back when I believe I may have been the only rider around who wanted such wide rims.
They were very hard to find, even in the late 1990's.
The original pro-level, old-old-school rim-brake rims for DH were the narrower Module-3 rims (25mm outside width). RhynoLites came later, but were similarly super-strong, even heavier, and just as hard to mount tires onto.
Why such wide rims one might ask?
Because here and in the SW where trails can be loose, slippery hard-pack, the lean angles are almost never very severe, so better to flatten the tread cap to put more tread against the ground. The tread cap gets pulled toward the side that you are leaning to anyway, so one still might never run out of cornering tread.
The flattened tread lasts longer, and the tires feel more responsive to lateral forces, giving better communication from steering inputs.
The inexpensive(!) bike shown below came with much narrower rims, but I substituted i51mm(!) rims (from a box-store Mongoose) so as to get going with X-wide 27.5" wheels on the cheap, and running Shraeder tubes.
Still riding on these almost five years later, now using a 2.4" rear DH tire and an equally plump 2.3" Vigilante front tire, both inflated at 21psi. It's a formula that seems to work really well for my riding here in Auburn!

Would there not be some limit on how wide a rim you can use based on how close the canti bosses are spaced?
I am not thinking of tire clearance, but rather the relation of the bosses to the rim braking track.

I have 40mm-ish 26" rims on a bike, they barely work with V-brakes. Had to find a set of STX V-brakes that used canti pads so I could get more adjustment.
The rims are Echo trials rims, I can't recall if they are front or rear. Front trials rims are often 38mm or so, and a rear is more like 48mm. They still generally use rim brakes on the back of trials bikes, so you can find them with a brake track. Although some are pre-ground and you don't want that.
