When trying to upgrade to different sized tires, you will need to be aware of both width and height clearances between the new tire size and your trailer.

A trailer tire sized 205/75-15, like # AM10245, will have a diameter of almost 27-5/16 inches and a width of a little over 8 inches. A tire sized 225/75-15, like # LHWL304, will have a width at almost 9 inches and diameter that is almost 28-13/32 inches. The new tire will be almost an 1 inch wider and 1 inch taller than your current tire.

Now, if you have enough clearance on your trailer to compensate for a tire that is 1 inch wider and taller, then switching to the 225/75-15 tire will not be a problem. However, if you think that extra 1 inch in height might cause problems with clearances between the tire and trailer, you might have to modify your trailer or continue to your the 205/75-R15 tires.
