    This thread got me interested again in a 15” rear off - road tire but still could not find one small enough for my R1150GS. I looked for a US sourced tire. Has anyone found such a tire ?

    Off-road tire? You mean a big chunky tread pattern like you see on some pick-up trucks? No. Best you can do is an all-season tread. I just finished a 1200-mile off-pavement trip through Montana on my 1200GSA and my all-season radial had no difficulties. Admittedly, all dry gravel and dirt--no mud, no snow. Well, some mud, but just mudholes that you are in and out of in a second. With a chunkier tread pattern I could probably tackle a steeper hill with a looser surface, but I don't see much of those kinds of grades even in the Cascade backcountry.

    Here in the PNW, you can try the same tire I'm using available only at Les Schwab. Pretty sure Les Schwab sources these tires from Toyo-- https://www.lesschwab.com/ultra-z900-437983.html

    If you can squeeze it in there, a 205/70 x 15. Works out to just over 26" tall.

    Way to wide and doesn't fit a 4" rim.

    To make that fit, you'll need to shim the wheel to the left, to clear the swingarm, and move the exhaust even more to the left to clear that.
    165-175 is doable, but just.

    The question is: do you want an off road tread pattern or not? If you do, then you'll do what's required to make it fit. 205's have been done, ask Claude about his K100.

    This is a 195/65 x 16.

    Here's a 205 on an 1100GS --

    I had to move the exhaust and use a spacer just like @PaulRS said.

    Ok kids lets all play nice Ron made the mistake of saying 15" off road tire and the dog damn Luke posted a 15" off road tire dog damn is he hard to get along with or what :lol3 We haven't been able to get 15 " off road tires that work well, so we all use winter tires or all season !

    Luke’s got my tire. It’s that 205/R70 15 on that little white car. That’s what I would call an off road tire.

    That Yokohama is what I’ve been looking for, for the rear on the Bumblezookie. I’ll have to measure to assure the 7.8” width will fit. Now to find a mate for the front....

    The VW racers shave the lugs on the outside of the tread when using these for fronts to stop ruts or rocks grabbing the tire and overpowering the steering. Probably something to think about if using an aggressive off road car tire on the front or sidecar wheels. Or looking for a tire that doesn't have lugs that extend onto the sidewall.
    There is also a Yokohama Y742S that is a mud and snow pattern available in a radial 7.00R15 that appears to be a little cheaper. Like most in this size it is a light truck tire.

    Scott seems to do OK.

    My sporty with a 6.00 x 15 Yokohama. I can't imagine that you'd be able to gear a GS' low enough to be able to run a 7.00.
