    Wrathchild 4.6 on 90mm rim fit 2016 Specialized Fatboy?

    Hi, newbie here. A very basic question: would wrathchild 4.6 x 26 fit for both rear and front of a Specialized Fatboy using stock Stout XC 90 rims and running with tubes? I will probably be running at way under 20psi (closer to between 5 to10).

    If these tires are a no go what other studded tires do you all recommend for this frame.

    Thanks.

    Forgot to add these would be with the XL studs if that makes a difference.

    wrathchild on a 90mm rim is 4.585". i do not run higher than 7psi.



    fyi, XL studs suck. many have half of them fall out on the first ride...

    that being said, i love my wrathchilds, although with the smaller 45nrth concave stud.

    I haven't lost a stud yet but not much for rock riding just mostly on a pillow of snow. That being said I did a long ride on blacktop to help seat them before they saw any trail riding.

    I installed mine with some Balkamp (NAPA) Tire and Bead Sealer and did not lose one of them today, even locking up the rear tire on pavement. I'm calling that a huge success. The sealer made them seat a lot easier as well.

    Incidentally, I am VERY impressed with how they hook up. It was 8 degrees during my ride of 8 or 9 miles, to include packed and unpacked trails. I am coming from D5's in winter and Bud/FBR for non-winter (or winter with no ice) and these have more traction than anything I've ridden. I did not feel they required any more power than the D5's I've run for years. I purposefully went off trail into the deeper stuff a number of times and it just climbed back on the trail easily without washing out.

    They measured 4.51" on my 100mm wheels, tubeless, but they are brand new.
