Haha, ok, I am coming from 2,1 tyres on my hardtail, and the 2,35 NNs look fairly wide already.

Also, I see they mention something about the tyres being optimized for 30-35mm rims. I have i27. Would that be a problem?

Just picked up some Bontrager XR4 Team Issue 29x2.4, claimed 780 grams, even if they weigh a little more I think it'll be OK. Nice tread design too. You might want to check them out. I'll give a little feedback next week.

Apparently I chose the wrong tyres for i27 rims.

If narrower rims produce more round profile on wide tyres, this is not what I should get I guess?

Anyway this is confusing. They previously had, I believe, WT in the codes of tyres that were actually wide variants. That is now gone.

The WT distinction is still on some tires, it's just irrelevant now that wide rims are popular and all wider tires are made for wide rims. There are no 2.4"+ tires that Maxxis designs for sun 30i rims now. However 27i rims will work just fine for at least up to 2.4" tires and maybe wider depending on how much support you need. I wish Maxxis would drop the whole WT thing all together, it's confusing.

This statement deserves a little clarification. Stating "generally light duty tires" is a gross generalization and misleading. I've run them in a couple of flavors and wouldn't classify the use as "light duty" at all. Granted, you need to run the appropriate width rim (30-35iw) to support the sidewalls. For overall trail use, including some pretty gnarly terrain, it is a great width.

2.6" though is not in the plus category. I'd draw that line at 2.8" and up, which tend to find their niche in hardtails and rigid bikes. When your talking 2.4-2.6 widths you're really splitting hairs on width. Get a pair of calipers out, set it to 1.25mm, and that's the difference in width per side we're talking about...it's pretty small.

To be clear, most 2.6" and wider tires use lighter construction than 2.3-2.5" tires. For example, compare 2.6" Maxxis tires to their equivalent 2.4 or 2.5" version. The 2.6" version will typically be just as light or lighter. 2.6" tires are generally not scaled up versions of their narrower counterpart, they're lighter duty. There are some exceptions out there though.

I've gone through the phase of being focused on tire weight only to discover that for my riding, tire compound and tread design are more important factors than weight alone. Here in the Wasatch, Utah, I've tried some of the lighter trail tires by Maxxis such as the Ikon and Ardent and found them lacking. For my riding and terrain, I need more grip. I have used the DHF on the front in a 29" and the Aggressor on the rear in a 29" and really liked them, but they are heavier than the Nobby Nics. I had been using Nobby Nics in the 29x2.35 Evolution, Speedgrip version in years past and really liked them, but my understanding is that they recently redesigned the tire resulting in the new version being heavier, so I'm unfamiliar with this version.
The tread and compound resulted in a fast rolling tire with decent grip, I thought.

Anyway, one thing I have noticed about Maxxis tires is that they generally come in very close to claimed weight, but require stretching to get close to their claimed width. If you look at the 29x2.50 Aggressor, for example, it has an ETRTO of 63-622. It's the first number, 63 which is the width - 63mm or 2.48". It takes some stretching to get to 2.45" and that's at the knob width. If weight is the only important factor, and it must be Maxxis, I'd go to their site and go through the tires looking for something under 900 grams. My sense is that whatever you find may not have the grip of the NoNi's.

Here's their site: Bicycle Tires |Maxxis Mountain Bike
For your purposes, it may be that something like a 29x2.35 Forecaster at 735 grams might work well. I haven't ridden it, but I've heard good things about that tire, and its ETRTO puts it at 2.36".
Good luck.

Edit: I wasn't paying enough attention and only read the first page of comments, so I may have missed some things said in the interim. Oh well.

Yep, after some hard thinking and finding out about the wide rims catch, that's the one I ordered.
I decided to keep the Nobbies and just use them as rear, and the other one I will either sell eventually, or just replace the first one with it when it wears down (which might take a long time since the trail bike will mostly only be used when I go visit some bike parks, not for regular riding).

Fitting the Forekaster into the rims was a bit of pain the arse due to Maxxis' rubber being a lot more... well, rubbery, to touch, but thus far I like it. It seems to roll just fine and the weight difference is pretty good on my bike that might have a bit too large frame for me with the front wheel sticking out so much :D
I'm still thinking about replacing the rear Nobby though, I just hate the dead weight. But I couldn't google any direct comparison with Rekon, so I'm sticking with what I have for now.

I recently replaced my worn down Nobby Nic Pacestar with Forekaster. Seems like there's slight more drag than the NN, but that might have been because my NN was worn down.

The climb and brake traction have improved and overall very satisfied with the Forekaster in the rear.

I have already ran into the limit of the Forekaster it seems. Very damn trails, not ye muddy, but wet already (it's been raining on and off lately), and riding on a slight slope. I ended up falling few metres down into the stream :D
I'm glad I have Magic Mary and Hans Dampf stashed away for when I get me a new pair of wheels to quickly swap.

Yeah, jeremy doesn't know what he's talking about. 2.6 have many uses, are fine for trail use, and nowhere near plus nor light duty.

We're talking about rider weights ranging from 100-400lbs and this guy thinks everyone should be on a 2.4 because rationalizations.

Don't put words in mouth bush league. People can run 2.6" on whatever they want if they need a more supportive tire they'll figure it out.
