    largest tire possible on a ogre

    what is the largest tire that will fit on an ogre frame im thinking of getting one soon and was just wondering. would something like a 2.5 nevagal actually fit?i realize the website says 2.5 but has anyone squeezed a 2.5 or anything bigger on there just to see if it would fit. i plan on running the factory tires until they are done but want to reasearch tire fittment options for the future

    Btw, what rim width are you using? Because wider rims would have the tires sit slightly wider than narrower rims.

    Well, with front derailleur, and stock rims from the complete build, I was able to put 2.3" Big Apples on, if that helps. Not sure they would have fit with a much wider rim.

    I run a pair of Kodiak's (29x2.5) on my 2011 KM during the winter, with Stan's Flow rims, no problem with clearance on the fork, one of the tires has a slight wobble so if I run it on the rear I get a very minor rub, otherwise they clear the rear by a 1/4" give or take.

    I don't think a wider rim would make a wide tire much wider. Maybe I'm dumb. I have run 2.35 Big Apples with full fenders on my Ogre, and a 2.5 would be easy. If the rim was two inches wide, it would still fit. You're not going to add any rubber to the fat part of a tire by increasing rim width. The contact patch might grow a little, but it's not going to suddenly be able to get that much wider on the traction end of things. You open up the bottom, but the top ain't stretching.
    You have no excuse for driving to work
    (unless you don't have studded tires)
    (no excuse for that either)

    It would have to be a very wide rim to make a huge difference. The difference is mainly in the width of the casing, which can interfere with v-brakes and accessories with very wide rims. Here's a picture I always go to when talking about this. Both are 2012 1x1 framesets with the same size tires (Kenda 26x2.35), but different sized rims. The first are 65mm wide rims, and the second are 28mm wide rims (my personal bike).





    This may help the OP with what we are referring to, however this is an extreme example. The width of the rim will change the tire's looks, size and handling characteristics, but not by a whole lot unless you get a Rabbit Hole rim or something.

    I just mounted 3" Gravity Vidars on Velocity Blunt 35 rims on my Ogre. ~3.5mm clearance at seat / chain stays, fork fits fine. Had to put the wheel ALL the way back in the dropouts, which allowed me to fit a front derailer with no issues. Homebrewed an offset double with a long spindle BB and a spacer on the BB drive side. Mounted 38 / 22 rings. On the rear I am running a spaced 7 speed cassette, no chain rub. Haven't had a chance to ride it yet, just finished it and it,s dinner time. I will ride it tomorrow, and if it still doesn't rub, I will post pics.

    What front derailer did you use? I'm keen to experiment with custom doubles to achieve the max range.

    Your picture didn't work for me, but you're saying 29x3 tire fits in the Ogre?? How wide do the Gravity Vidar's measure once mounted?

    @big_papa_nut, I am using a Deore direct mount FD, with a Problem Solvers adapter.

    @2:01, Yes, the Gravity Vidar is branded as 29x3, and it fits on the Ogre with Blunt 35's. I don't have a set of calipers, as soon as I find a way to measure, I will post.

    @seat_boy, I can't seem to get a good pic of the clearance at the stays, trying to figure out how to get the camera in close enough.

    @2:01, It makes me very happy also! The best part is 2 tires with tubes was under $80 shipped.

    I was able to measure the tires on Blunt 35's:
    Casing = 67mm
    Knob to Knob = 71mm
    Clearance wise, the height of the tire is an issue also. Not sure how to measure, but they are tall.
    Haven't been able to hit the trails yet, only gravel / dirt roads. It is definitely quicker to accelerate and more agile than my Pugsley, but also less sure footed.

    Efuss - I'd love a status update to know how these worked out for you and whether you've had any issues!

    I'll reiterate what everyone else has said - you've made a lot of KM and Ogre owners happy.

    @Martin.M.Clark
    It is snowing , so been riding the Pugsley for the last 2 weeks. The tires definitely fit, clearance is close at the stays, I can make it rub a bit on hard out of the saddle climbs. No chain rub with 3x7 drivetrain. If anything, this setup has given me the 29+ bug, I just bought a set of offset Rabbit Holes for the Pugsley.
    My ride impressions are in comparison to the Pugsley, the Ogre was not ridden much since I got the Pugs. I definitely prefer the traction and cush of 3.8" Nates over the Vidars, but the rolling resistance is much less for the Vidars. I haven't set them up tubeless, but tubed at 15-20 psi, the Blunt 35 / Vidar combo makes the Ogre more capable as a mountain bike. The tires don't seem to roll over or self steer, just more traction and plush compared to the Ardent 2.4's I had on there.
    Most likely I will move these tires to the Pugsley when the new (to me) wheels get here, and see how I like it.

    You can fit a 3" tire on a 50mm rim on the front.

    And a 2.4" tire on a 50mm rim in the rear.

    Sorry, I couldn't get a decent pic, and I have swapped the tires over to my pugs. Clearance was tight, but no rub when climbing. I used a chain tug to pull the wheel to the very end of the dropout. 1 or 2 monkey nuts wasn't enough.

    A little thread resurrection here,

    Right now it seems clear that some + tires fit on the Ogre. I believe it would be nice to have a list of them. My Ogre has at least 76,5mm of 29er clearance on the rear, just for starters. Not sure about 27.5plus clearance, as I don't know where the widest part of the tire would be.

    29plus tires that seem to fit the Ogre/KM (at least with 30/35mm rim)
    - Vee Trax Fatty
    - Panaracer Fat B Nimble
    - Gravity Vidar
    - Surly Dirt Wizard

    27.5plus:
    - WTB Trailblazer
    - Panaracer Fat B Nimble

    Some of this tires are known to fit the Ogre by users posts, etc. Others are by tire measurements only, like the Panaracer 29x3.0 or the Surly DW

    My recent experience with trying to fit 29+ in the back of my KM, I modified/squished my chainstays and tried a 29+ maxxis chronicle on a standard KM rim and also a velocity blunt 35. I also had to move the axle literally all the way to the far back of the dropouts, unsafely far back.... I do not recommend trying to install 29+ in the back Of a KM/Ogre,
    however I would consider running a standard sized 29er tire 2.2-2.5 on a 35-45 mm wide rim back there or possibly trying 27.5 plus

    The Chronicle/Knard/Chupacabra are considerável bigger than the tires I posted. As an example, the Fat BNimble seems to measure 68mm on a wide rim

    You can fit 29+ on the front of KM/Ogre, but 29+ will not fit on the back, I would recommend sticking to 2.5 in max width for KM/Ogre rear tire no matter what the brand or model, 27.5+ will most likely fit, I just have not tried it my self. That is a pricey experiment

    The Chronicle/Knard/Chupacabra are only ever so slight bigger than Vee Trax Fatty/Gravity Vidar/Surly Dirt Wizard

    For what it's worth Maxxis Chronicle have a EXO sidewall protection option and the are BAD ASS!

    The size difference is not that small. The tires I specified are closer (or even under) 2.8 than 3.0.

    The Panaracers seem to measure at 68mm max. Panaracer Fat B Nimble next to a Chupacabra:


    The Vee Trax Fatty are 70mm
    Here on a Karate Monkey (same clearance as the Ogre) on Rabbit Holes:


    The Trax Fatty on a Dually (45mm) rim:


    Even Surly admits the Dirt Wizards are 2.8 tires. Most sources measure them at around 69/70mm.
    Next to a Knard:

    Re-resurrecting. I'm heading out to do Kane Creek and I'm going to try to squeeze a Specialized Ground Control 3.0 on the front and a WTB Ranger 2.8 in the rear, both on Velocity Blunt 35's. Will update w/ pics n' sech.

    What's the width on a vapor trails? I'm hoping the new ETs on Rabbit Holes will fit on the back of the Ogre. Any thoughts?

    No longer vaporware, I have a pair of Extraterrestrial 29ers in my grubby little hands now. I just have to build my RH's and see how they fit. Tubeless brew check, spoke meter check, dishy tool check, rabbit holes check, ogre check, knowing how to use it all? well we will see.

    These won't be largest tires on an ogre though, will they?

    They fit on the back of a MDS dropout Karate Monkey. See my recent post in this thread.

    They'll certainly be one of the largest that'll work with Rabbit Holes. I eagerly await the report of your adventure! From the thread Larry Endomorph pointed to, I'm optimistic. Curious about the drivetrain requirements....

    My set arrives today I am beyond excited for these rims.

    In winter I run a set of 29x2 Marathon Winters with full fenders (PB ALX) and in the summer I run the same fenders with Big Apple 29x2.35, everything has worked fine however this year I went 3x10 versus all other years I was using an IGH. So I did Surlys trick with the rear fender and using the 30mm spacer with a 40mm button head bolt. To be honest I am a bit nervous if the big apple will fit on the rear without rubbing, I did not want to slam the wheel all the way back in the dropout. If they do not fit I plan to see if I can find some 2.15 or go to the 2.00 big apples.

    EDIT: Prior to the Dyad on the rear I ran the IGH on a Salsa Gordo rim which has an internal width of 29.8 on a 35mm rim so it is a wide rim.

    Think there's much chance that the ETs will fit on an Ogre and clear a set of 65mm Planet Bike Cascadia fenders? I love the width, tread pattern and kevlar belt, would love to put a set on my commuter to make it more plush & offroad capable.

    Been thinking of building up a 25-30mm rim wheelset to make this happen. Does it seem plausible?
