    How big are these 2.6" tires really?

    I have seen some pictures and herd some reports that some of the 2.6" tires on the market are actually measuring closer to 2.4". I have a bike with 2.4" Trailbosses (that measure ~2.4" on 25mm rims) that I think would benefit from bigger, or if possible taller, tires but don't wanna spend the money on rims and tires for no real changes.

    Anyone have measurements on any of these new tires? Rim width, tires width, and tire height would be ideal.

    The Nobby Nic 2.6 are 65-66mm wide on a 35mm inner width rim. If you choose a slightly narrower 30mm rim the tire will shrink by 50% of the subtracted width = 66mm - 0.5*5mm = 63.5mm

    This. My NN 29x2.6 on 35i rims are 65mm.

    I have Maxxis Rekon 2.6 on a 29mm inner rim. I was previously running Ardent 2.4 on the rims and they measured true 2.4 at riding presure. The Rekon measures 2.5 at riding pressure after some miles an stretching by pumping to max inflation while the bike is at rest between rides.

    Although 1/10th of an inch (2.5mm) doesn't sound like much, the Rekons have significantly more volume and grip than the Ardent. It was a very noticeable performance increase. Rolling resistance increased on hardpack, but it was a fair trade. Plus, they look so bad@$$ on my Trance.

    could you post some pictures showing frame clearance with these tires?

    I'm thinking about Nobby Nic 2.6 on a 30mm rim rear / 35mm rim front

    Hi Mr. big_papa_nuts,

    I don't have tire height for you but my Schwalbe Nobby Nic 29" x 2.6" tire mounted on Derby 29 mm ID width rims measure 65 mm (2.56") at the sidewalls when aired up to 16 psi. It's one mm smaller when measured at the side nobs. I did leave the tire mounted up for a few days at 40 psi before it "stretched" to that width at my normal riding pressure of 16 psi.

    I've ridden it quite a lot in the last few months and really like the tire!

    Good luck,

    Michael
    If you can't keep the rubber side down......at least smile for the camera!

    I have the hardest time getting pics from my phone to the forum.

    There is a min of 6mm and a max of 8mm all around. The tightest clearance is at a weld on the vertical brace between the tire and seat tube.

    2.6" tires are about two and six-tenths of an inch.

    No way! It's more like 2 and 3/5'ths.

    Just mounted Rocket Ron 2.6's on Ibis 742 rims and they're 2.6 on the dot. I assume they'll stretch a bit.

    Seems like the rim could make a noticeable difference.

    2.487"


    Then I moved on to the 2.6" Rocket Ron on the rear Czero rim:



    2.458"

    I'm just about to get a pair of 742's (my wife's getting the 735's). My RR's are more like 2.48 on smaller rims....looking forward to seeing the difference.

    2.6 Nobby NIC on WTB KOM i29.
    How big are these 2.6" tires really?-img_20170605_135201895.jpg

    Also tried a 2.8" WTB Trailblazer, which fit in my standard Pike but only had 2.5mm of clearance. So I guess I'm now searching for narrow/short 2.8s.

    A 35 mm internal rim would be a better fir IMHO.


    As far as how big? My Nic 29x2.25 were exactly 29" high, and a circumference of 90", the Nic 29x2.6 is 29.5" tall, and 92 inches in one revolution. Width as mentioned is 2-5/8" eyeballing it.
