    I was wondering if the tire off of an 84 XV700 will fit on the XJ700. All of the internal and external parts are the same. My concern is the rim size. The XJ700 tire size is 130/90-16 and the XV700 seems to have an 150/90- 15. Will there be any problem mounting an XJ700 tire on the XV's rim?
    Thanks for any insight on this.
    Cheers
    Ken :D

    On the side of every tire is a host of numbers and ratings that describe the tire and its performance characteristics. A typical tire size numbering system will appear as a string of letters and numbers, such as this example: P215/70R16 100S

    P215/70R16 100S

    The first digit in the tire size indicates the type of tire and intended use. In this example, the first digit is “P” which indicates the tire is a metric size, used primarily on passenger vehicles. Other letter designations include T (Temporary Spare), LT (Light Truck Metric), C (Commercial), and ST (Special Trailer Service).

    P215/70R16 100S

    The following numbers before the slash (/) indicates the section width of the tire; the widest point from sidewall-to-sidewall. The larger this number, the wider the tire. This number is the wide of the tire in millimeters. In this example, the tire has a 215-millimeter section width.

    P215/70R16 100S

    The next number trailing the slash (/) indicates the height of the tire in a percentage of the section width. In our example, the number is 70, which means the tire height is 70% of the section width, which is 215 millimeters. The height of this tire would be 150.5 millimeters. The lower the number is, the lower the profile of the tire.

    P215/70R16 100S

    The next letter is reveals the construction of the tire. The most common is “R” such as found in our example. The “R” designation states the tire is of radial construction. Other construction types are rarer for modern passenger car use, and may include “D” for bias ply construction and “B” for belted tires.

    P215/70R16 100S

    The number following the construction code is the size of the wheel in inches. The example tire would be designed to fit a 16-inch wheel. Tire sizes on modern vehicles typically start at 13-inches and go up to 18-inches, but aftermarket and special package wheels can be 22-inches or even larger.

    P215/70R16 100S

    Usually following the tire size information is the tire performance information. The first number, in this case “100” designates the load carrying capacity of the tire. This particular example would be rated for 1,764 pounds. Load ratings generally start at 71 (761 pounds) and go up to 110 (2,337 pounds) for passenger vehicles.

    P215/70R16 100S

    The final number in the tire performance rating is the speed rating. In this example the speed rating is “S.” This tire would be rated for 112-mph. Speed ratings start at M (81-mph) and go up to Y (186-mph). If a tire is rated Y but the rating is enclosed in parenthesis, this means the tire has been tested at speeds greater than 186-mph. If our example tire was rated 100Y and tested faster than 186-mph, the performance number would be (100Y).

    well for starters your dealing with two different rim sizes, so straight out... No, the 130/90-16 won't fit on a 15 inch rim. 150 is really wide and I don't think it'll fit on an XJ, at least not on my 750 or most other ones but im not positive about the 700's

    Basic breakdown of tire sizing is:
    First number is width in mm (130mm)
    second number is height by percentage (90% of 130mm)
    and the last number is the rim size. (16" for xj, 15" for xv)

    I believe that there are different size tires that will fit on the same rim. I do know that a 150/90/15 will be to wide. But will a narrower tire fit on the same rim and not rub against the drive shaft I guess is what I'm asking. The 130/90/16 are about as wide as will fit on my bike. But, will the rim of the XV700 accept a narrow enough tire to fit within the space allowed by the XJ700's drive shaft yoke and still work?

    so what your asking is can you use the 15" wheel from the XV on your XJ if you change the size tire it has on it.

    IS that right?

    I don't know if the wheel will work but i can tell you you can mount a narrower tire on the 15" XV rim with out a problem. My question is why would you want a smaller wheel with a narrow tire? :?

    The reason I'm asking the question is that some of the XV's come with spoked rims and all of the drive parts are the same as the XJ's and, I thought that it would give my bike a better look if, I can make it fit. Thanks for all the help.

    Oh and BTW, the narrower tire is what is standard (what the manual calls for) on the XJ.
    Thanks again
