Question:

In the attached picture the new tire is the one of two I ordered from you guys. The old tire came off pontoon boat trailer. I really need to know which tires to order. Is there not a way of telling by the attached picture or year and model of pontoon boat and trailer? 1998 Sun Tracker single axle trailer. I have searched the internet for information. Any information you may have would be appreciated. I would like to get them ordered ASAP. Lakes a callin

I zoomed in on your picture and your current tire size is 20.5 x 8-10 which is an older size the is most like the current size 205/65-10. You purchased Kenda tires, part # AM3H390, which are 205/65-10 size tires.

The problem it's on the wrong rim. Part # AM3H390 has a 5 on 4-1/2 bolt pattern and a 2.8 inch diameter pilot hole. Your bolt pattern looks like it's a 5 on 5-1/2 and your pilot hole is probably 4 inches in diameter. I can't tell this for certain by looking at the picture but you can measure it. Just measure the diameter of the center pilot hole and see if it's 4 inches. Then measure from one bolt hole to the next one center on center like in the diagram I attached. If that equals 3-1/4 inches then your pattern is 5 on 5-1/2.

If I'm correct about your pilot size and bolt pattern then you need part # AM3H454 instead.
