    Available lightweight tire options?

    I should probably just wait for the lightweight Husker Du's to come back in but open to suggestions. Running stock 27tpi Nates on my Muk. So...

    Ultralight Nates: more of the same, but lighter?
    I was told to avoid Escalators for durability issues.
    120tpi Knard: too soon to tell?
    Just wait till September and get the HuDu's, stoopid.

    Weight, grip, and toughness priority over rolling resistance. Everyday trail use with plenty of rocks. Figure I could always put the Nates back on for the snow if I got something like the Knard. With drilling my Darryl's, hoping to knock off around three real pounds. That would be fairly awesome.
    Thanks!

    Tire Weights for Fat-Bikes | FAT-BIKE.COM

    My next set are going to be knards, I've seen enough mention of people getting more miles out of them than hudus and the weights are much the same.

    Me too. I reckon they'll be very similar.

    The soft compound on the HuDu's make them very grippy but not worth a sh1t when i have to replace $150+ tyres after 4 months.

    FYI, the early 120 Knards that I bought 8 months ago were both well into the 1400 gram range, so keep that in mind. Also, they are pretty small width-wise when compared to just about any other fat tire. My guess is weights have stabilized, but they are still a 3.7-3.8 casing. Nice, fast tire but a little slippery on the wet stuff.

    Offcouse-Ran across that weight chart just the other day, really good info there. What are you riding on now?

    Ozzy-I'm not terribly concerned about wear, the Muk is essentially a third bike. Then again, if this all goes well I'll probably ride it more. And 4 months@ $150 a pop, damn.

    Deux-how were they on height? The BB is really low now. I'm a little worried about the HuDu's as I've read they are shorter and fatter.

    There are no official weights listed on these tires so the manufacturers are covered, but it'd be really nice if the dopey things were SOMEWHAT consistent! I'm looking at $300 bucks here to accomplish a specific thing, less weight. The HuDu seems to have been sorta consistent but I didn't realize they were a QBP product also. So who knows. Don't mean to sound whiny here, it's all for fun anyway.

    Thanks very!

    Most of us use our fatbikes as a goto bike for the majority of our rides, my bikes have never seen snow and are ridden on 90% dirt and occasionally sand. If money and wear is no object then give the HuDu's a try but after every ride have a look at your rear tyre, it wears on a daily basis.

    I have a brand spanking set of HuDu ultralights here still in the packaging and will be putting them on for a race that's coming up. Awesome tyres but for daily rides you'll need deep pockets and a proactive approach to buying them as they don't hang about too long when available, if you think about buying them for any amount of time when they become available.... the decision usually gets made for you

    So...when you can find them, buy them, unless you can't.

    I have a pair of 120 tpi Knards. They weighed in at 1315 g and 1340 g so they are not exactly lightweight. Other "disappointment" is, that after 2 months and maybe 700-800 kilometers (mostly on asphalt for some reason) they show very little wear, so it seems that I cannot justify buying lighter tyres in near future

    I think they perform well, but I can't say anything about wet stuff, as we have not had a proper rain since...can't remember when, which is quite odd as I don't live exactly in an area that could be described as arid (SW Finland).

    EDIT Don't know if this is of any help, but their max casing width on 65 mm rims is about 92 mm and their height seems to be comparable with Larry on 82 mm rim, but it seems that Larry has rounder casing profile (if my eyes do not betray me) even though it sits on a broader rim.

    I'm thinking I'll run a knard up front and a Vee 8 in back, then switch to escaltors in the winter. I'll be going ghetto tubeless tonight.

    My bikes in pieces in the garage (anodizing the fork to match frame but I've have on-one floaters on since I torn open a hudu on an oyster shell
    The difference in rolling resistance is huge between the two (floater/hudu) but it's winter here ATM so its all good I will play around with the floater on the front but I can't see one going back on the rear in the future unless I go do Thompsons Track again in the summer ;-) Thompsons Track 2009 - The Mighty Rock - YouTube

    Man, I'd jump on the 120tpi Knards if I could be (kinda) sure they'll hit around 1300g. Assuming they're on the same casing as my Nate's I shouldn't lose anything size wise? Too bad the Floater isn't a bit lighter. The Vee 8 looks neat, but I as much of a tire whore as I am, wonder about handling.
    HuDu still seem like the lightest that works well, but maybe I'll see if any local shops have some Knard's. At around 1300g I'm still shedding close to a pound per.
    Thanks for all the feedback, very cool.

    There are reports that the Vee 8's self-steer; I've run Vee Missions on my rear tire without issue- they're fast, but heavy and on the rear, handle just fine. The Vee 8's are supposedly at least a pound lighter; combined with a Knard up front, they should handle well.

    Yeah it was the self steer that had me concerned. Maybe. Thinking pretty hard about the Knard, some DH tubes, drilling (which I could do anytime but going for max effect) and maybe a spiffy fork. 30lbs? That'd be insane considering it was 36.9 on the shop scale day one!

    The hudu's get self steer if you have them to low on hard surfaces......if you need anymore convincing
    It sucks having to pull out the pump if your just going for a quick ride down to the beach and back.

    Like how low? I usually run around 10psi in the Nates.
    Thinking. I'm going away half of August so maybe wait till September and see if the HuDu's pop up anywhere.

    For the record, I love my Escalators. I did have 1/4" sticks go through the middle of the tread (twice!), but that was months ago, and they're still going strong. I didn't bother patching the tire. So yeah, they seem flimsy, but only slightly more so than the light HuDu's. I scored mine for $117 off the innernetz.

    I pulled the plastic packaging off my HuDu's today and weighed them, tipping the scales at a spritely 1250g and 1230g.

    Andy likes them too, but I think he already flatted one. Otherwise, a decent choice. Argh!

    Damn, that's more than a pound less per, based off average 27tpi Nate's. Want!

    I'm not brave enough to run that low, plus I haven't yet hit a beach. So, should be good. Called my cool fatbike-digging-LBS today (actually the shop that got me into it), they show HuDu's available beginning of September so they have my name on a set! I gotta get my rims drilled in the next couple weeks then.

    Talked about the Carver O'Beast fork, they were all for the idea but suggested I wait and go 15mm as it seems the market is leaning that way.

    Is there a need for a 15mm thru axle on a fatbike on rigid forks?

    Ive had bolt on 10mm, 15mm through, 20mm through and even the white elephant 25mm through axel on my 2008 Specialized Enduro, all my bikes are fully rigid now and all run QR axels. I use Halo bolt on skewers on all my bikes except the rear of my fatbike which has a salsa 170mm, they all get ridden HARD on dirt and I can tell you I notice no difference in stiffness between QR or 15mm on a fully rigid bike.

    Both my MTB's run Carbon Fibre wheels and my fatbike has 65mm rims so basically zero flex coming from the wheels, couple this with rigid forks the bike steers like a pizza cutter, all the play/flex on a fatbike will come from the tyres anyway.

    If you have suspension forks then there is probably an advantage YMMV.

    I agree, I don't think it's necessary on a rigid. I believe the shop is trying to help "future proof" me as they feel 15mm will become more common. I can see the wisdom in that. I recently built a bike and went 10 speed even though I had a few 9 speed bits lying around. Thinking, better to be ahead of the curve rather than behind?

    Entirely possible I'll just do the fork anyway, knowing me. Have to think about it, as I don't need a new hub then either. Thanks!

    Something to think about relative to fat ultralight tires is that weights vary considerably between samples of the exact same model. So if you have the ability weigh a bunch of tires and pick the lighter ones. You can get weight loss at zero cost, but it requires access to a supply of tires.

    If you are ordering 1 or 2 at a time mail order you are at the mercy of whomever is grabbing them from the bin at the warehouse.
    Safe riding,

    Weight variation applies to any tire. The bigger the tire, the greater that actual weight difference can be. Plus or minus 10% from target weight is considered normal. +/- 20% is not unheard of.

    The shop is ordering about a dozen, hopefully I'll be near the front of the line and get to handpick. If not...one of the reasons I decided on the HuDu's is they seem to be the lightest aggregate tire that I'd want for all around use. The heavier HuDus I've seen measured, minus the lightest 27tpi Nates, still seem to get you at worst a reduction of 400g or better. Since I'm going for 1 pound per tire, i can live with that.

    I have a pair of ultralight HuDu's, currently at 1209 and 1215 with only a bit of wear. I am liking Larry/Knard combo better. I have been thinking about selling them and getting an ultralight BFL for the front. The HuDu's are super light and fast but a bit too squirrely for me at the pressure I like to run. Super grippy though and if you want grip and light weight, they are the way to go, for sure.

    You can feel the weight difference from wire bead larry and folding Knard.

    Didn't want to start a new thread, but wanted to make you guys aware that I keep hinting fatbike tires on the Kenda Tires FB page. Basically, anytime they post an image I can somehow relate back to fatbikes, I remind them how they don't have any fat tires. I'd like to see a community effort to keep pestering them

    You are assuming they have the capability to make fat tires. As of 18 months ago only Innova (Surly, 45N) and Vee Rubber could manufacture fat tires.

    The machinery. Can only produce tires that are so wide and/or tall. If the casing is wider than the layup drum or the molds larger than the vulcanizing machine it can not be done.

    Another point for this here thread is the fact you can get a tube from Schwalbe that inflates to 26 x 4.0 that weighs is at 185g! :-)

    So knards & schwalbe tube = 1500g

    All 3 companies also make motorcycle tires. Can those machines be used/adapted for fatbike tires? Or did Innova and Vee invest in new machines specifically for fatties?

    Moto tires are smaller than fat tires.

    It seems Innova and Vee Rubber already had larger equipment.

    I have three and they weighed in at 199g, 202 g, and 203 g. So, a little more than advertised, but not bad They inflate quite nicely to 4" tyres with 82 mm rims. I have gotten a few punctures, but mostly due to user error, such as snakebites when riding up or down stairs with too low pressures...

    +1 - I understand why it happens, but at some point it becomes significant enough that tires should be graded and sold tires by weight.

    In other manufactured products areas the products are evaluated, graded and sold based on their actual attributes.

    I weighed mine on the kitchen scale and it was pretty close to the 185g

    I can see that punctures might be an issue however, once blown up to 4.0 then it could be a paper thin rubber!!

    Available lightweight tire options?

    That is several a several hundred thousand dollar per machine investment. Plus the space to use them. Can not just replace the old equipment or the old fixtures/molds may need replacing, too.

    So knards & schwalbe tube = 1500g
    Heck, I and used Kenda standard weight 26x2.1-2.35 tubes in BFLarry. No blowouts or punctures but they did suddenly deflate a couple of times, with no holes found in the tubes. Was able to just reinflate and they held for days.

    Just picked up a fresh pair of 120 ultralight Husker Du's.
    1278 and 1286 grams, no reason to distrust the scale. Heavy for them, but what can you do. Thought I'd share!

    Edit: looking at the fat-bike.com weights, they seem pretty in line with the older 120tpi, but not the newest (2012 up) ultralight. Am I misreading that aspect? I assumed since the tires were on back order chances would be that I'd get the newest variety. Maybe NOS?

    Looking forward to pulling my Nates off and hitting the scale with them.
