    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.

    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.

    Your pictures are now working. You may have just made a lot of Ogre/KM owners very happy.

    @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.
