    Tire Sizes

    My 85 GS550E has a stock 110/90-18 tire which needs changing. Local dealer has 130/90-18 and 120/90-18 tires on sale, will either one fit?

      I've got 120's on both of my 550's, one a 17" and the other an 18", and they both seem to handle fine. The rim is fairly narrow on my bikes, 2.50 I believe, so you don't want to go too wide or the rim will force the tire to pinch in.

      To measure is to know.

          The stock size will handle better on the stock rim though. I'd get a 110 rather than putting a 120 or 130 on there, which would make it handle worse.

              A: Is the proper size still available?

              B: How much are the discounted tires compared to the proper size?

              C: How much do you value good handling for the next several thousand miles?

              D: Is the value of B considerably greater than C?

              Wider tires can help with traction on a car, but not usually a good idea on a bike with narrower rims.
              If the stock size is not available, only go up one size to the 120.

                  Or suck up and pay the extra for the stock sizes.
