    Hi all,

    I have to replace the stock rear tire on my 2010 Triumph Bonneville T-100. I have a CSM Freedom Bullet sidecar mounted to it. I would appreciate any recommendations on a choice for a new rear tire. This motorcycle is for sidecar duty only. I do not remove the sidecar.

    Thanks much!

    No good options with out a custom wheel. I would go with a cheap tire. Cheap tires tend to have harder rubber and last longer. Even if it does not last longer, at least it was cheap.
    BTW, we make new from billet triple tree's for your bike that reduce trail for lighter steering.

    Yes, stock tire is 130/80/17. Any recommendations on good, cheap, hard tire?

    Shinko 705 or 700 are 2 inexpensive tires that come to mind. The 705's do pretty well.

    I have the same problem tire size wise. The only other option is to lace up a different wheel, which opens another can of worms and your wallet.

    I put a Shinko SR712 front and 130/90-17 rear on my Bonnie. They have about 1500 miles on them, still look new and they are really cheap.

    I'm prepping to do a rear tire change to my Bonnie too. Here is my line of thinking thus far.

    The stock rear tire is a 130/80 R17. I obviously want something with as flat of a profile as possible.

    This tire size gets us close to the size of a compact car spare, right? So why not check it out further?

    I found a tire called Continental CST. I like the tread pattern and the price.

    I have found it in a 125/80/17 and a 135/90/17 here in the US.
    http://simpletire.com/continental-cst17-tires

    I really like the idea of the 135/90/17 because it gives me about a 1" increase in height, which my rig could use. But I haven't sold myself on this because I'm not entirely sure how these will mate up. If I recall correctly, if a car tire mounts up to a 5.5-6" rim on a car, you are going to want to mate it to a slightly more narrow rim (4.5-5") on a motorcycle. So I'm still marinating on this for the time being. I've got 6 more weeks until I'm reunited with my Triumph, so a lot of thought is going to happen between now and then.

    those conti cst's are listed as temporary spares, does it still work good as a bike tires? do they fit a bike rim like on my gl 1000?

    I have no clue. :lol3

    This is really kind of an experiment in my head. They are certainly load rated and speed rated high enough for a hack. I imagine they would be very structurally sound too.

    I'm getting conflicting specs on the CST17. This site lists the speed rating at an M, which would put it at 130kph/81mph. I regularly run my rig at 70-75, so this is cutting it a little close.

    http://www.ityre.com/en/tyres/catalog/continental/size/62807/

    Also, being that it is a spare, the tread depth should be lower, but still deeper than the average motorcycle tire. Nevertheless, with the speed rating, I'm not sure that this is worth investigating further.

    the speed rating like all ratings like it is normaly with a big safety margin. and the bike is much lighter than a car. Im more worried how it handles on wet roads etc.

    I just measured mine - it is 6 inches wide and 3.5 inches high. I believe width is not a problem. 0.5 inch increase in height (as measured from rim to edge of tread). This will definitely fit a T-100 wheel.

    If we are comparing a stock 130/80/17 to a 175/55/17, there should be a decrease in height since the profile (sidewall height) on the Potenza is smaller. :huh

    My bad eye sight - 175 is about 3.25 and 130 is about 3.5. It looks like (almost) a perfect fit.

    No sweat. I was about to get excited when I saw the numbers, and wanted to verify. I absolutely cannot afford to go any lower on my Bonnie rig. If anything, I'd like to find a taller rear tire to help get a little more clearance. Looks like I'm just going to order a Shinko 705 and be done with it.

    Height is an issue for me as well but I think I am going with Potenza - it has served me well on my other rig. Now for replacing the sidecar wheel and tire...

    Dang, I was about to order a rear tire when I realized that I have a new 140/80/17 Tourance sitting at the house that I just pulled off my new Husky TR650. I suspect it can find a home on the Bonnie instead of rotting in the garage.

    Anybody run a 140 on a Bonnie before? I think it will fit just fine, but I'm a long way away from my Bonnie right now and can't check clearance.

    It should fit nicely - with a slight increase in height.
