    Tire clearance..how tight is too tight?

    I have a ti Jones with Salsa Gordos. I have been running a 2.4 Ardent in the front and a 2.25 Ardent rear. I am not a huge fan of the 2.25 and wanted to put a 2.4 on the back as well. The 2.4 once the casing settles in is pretty darn big , however the clearance is super tight. Tight enough, that when I get out of the saddle there is contact with the frame. I ride in dry conditions, so mud is not a factor, but wanted to know if this is bad for the frame and or stupid to do in general. Am I pushing it? Should I give up my dream of a marshmallow rear tire and slap on something leaner? Thanks.

    I would think that letting the tire rub even a little bit will eventually wear into the frame.

    I tried running 2.35 Rampages on my Gunner and it did rub but only in the off camber sections. 2.1 is about the max I can run on the back.
    Singin' I love hike a bike!!!

    It has clearance it is just minimal. Also the Gordos make the tires sit wider, so that is not helping, and the seam of my rim is slightly uneven which causes a "hop" that can't be trued out. If I mounted them on Flows it wouldn't be an issue. The weirwolf 2.55 was also not a problem even on the Gordos. The Ardent 2.4 are just monsters and have wide side nobs.
    That being said, its a bummer not being able to run the 2.4 Ardent in the back without the occasional rubbing.

    Trim the side knobs.

    The trouble with common sense is it is no longer common

    Yup Or maybe lace up a Semi in place of the Gordo. Their ERD is only 2mm off so you could probably use the same spokes so it wouldn't cost much. No point in having that massive rim if it's TOO wide. Save some rotational weight and run the tire you want...

    Not that my way is the best way, but I used a big set of wire cutters. Something like this:

    A sharp side cutter as DF... posted works great. Just clip off the outside corner.

    Had to do the same thing on my tandem to get the big Ardent to fit in back. Clipped the side knob edged off. Gained 3 mils per side. All fits really well now.

    Also, there should be a bit of room for debris to get sucked through the gap. I know a guy who crammed a 650b rear tire in a Turner. Worked great, but tiny bits of gravel and twigs would get sucked through the gap all the time. You could hear it, and sometimes feel it. Seems to me that it would only take a slightly larger rock to actually do damage.

    I'd have to concur with this statement, very sad indeed Even if I had the money sometime in the future this definitely took them off any fancy bike list I had.

    It is a huge challenge to build a bike with very short stays, 29" wheels with super fat tires and super wide rims to all work together in harmony. Again the 2.4 Ardent on Flows would not be an issue, and the 2.55 weirwolf on the Gordo wasn't a problem.
    But I hear you, I want to have my cake and eat it too.
