    There are so many places.

    If you want to buy local, try a Tractor Supply, Harbor Freight, or something along those lines.

    If you buy from the web, shipping kills you. Unless you work a deal with someone on Ebay. I email them and ask to sell off of the "bay" and then they don't have to pay them their %. This was they can pass that along to you.

    I know that when I sell my used ones, I have to sell local. Either that or just give them away because shipping makes them cost more than local, even if you sell cheap.

    Look on the side of the tire most are load range B Load range C is better Load range D is even better They even make a load range E in a 13 inch but I am not sure it's avalable in a 12 inch or not You may have to go with 13" wheels to get some of the higher load ranges you are looking for. A good tire store should be able to help you out, Tommy Jordan

    Read up on ST type trailer tires. Lots of load range info on the net.

    In addition to tire weight ratings, you also should consider the trailer axle and spring ratings, and the trailer frame ratings/strength.

    Whatever component has the lowest rating, that is the maximum legal load for the trailer.

    Of course, for a pair of tires, the combined load (trailer + PWC) is supported by both tires, and the tongue weight is supported by the tow vehicle, so that portion is not carried by the tires.

    ST trailer tires are rated for maximum of 65mph at the sidewall label air pressure and maximum tire loading.

    You can go (modestly) faster, but you must not be at the maximums for all measures at the same time.

    Go with load range c on bias ply or go with radials, the only one I know that makes a radial 12 inch is secura. http://www.trailerandtruckparts.com/...a__p__535.html

    5.30-12 Nanco Bias Ply Trailer Tire Load Range D

    Size: 5.30-12
    Rim Width: 4.00 inch.
    Tire Type: Bias Ply Trailer Tire 8 Ply
    Overall Diameter (OD): 22.1 inches
    Section Width (SW): 5.3 inches
    Load Capacity: 1,250 lbs.
    Load Range: D
    /8
    PSI: 105

    I would think that tire is going to ride VERY hard, and bouncy.

    What is the load weight you need this trailer to carry?
    Any idea what the unloaded trailer weight is?

    What are the ratings numbers from the VIN plate?

    In general, as the tire load range increases, the air pressure gets higher, and the tire rides harder.

    In general, a larger tire size with the same weight rating will have a lower load range, and ride softer with a lower maximum PSI.

    Can you fit a larger or wider ST tire on that axle?

    No I cant go with a larger tire due to the fender clearance. I have 2 GPRs and I would guess the trailer weighs 500lbs soooo


    GPR lets say weights 600lbs each
    +
    trailer 500lbs

    that puts me at 1700 lbs

    No there is no tags on the trailer it is a double Sport trailer here is a link to the trailer I talking about

    those D's will be fine. Keep them out of the sun, and watch the tread wear.
