Will There be an Issue in Changing from 205/75-15 tires to 225/75-15 tires on a Trailer

Question:

Im not sure you will know the answer, but I have a Bigtex 60CH car hauler trailer. IT has 205/75R15 tires on it now. I wanted to see if I can move up to 225/75R15 tires. With the wider width, Im fairly sure there is enough clearance, but thought Id ask to see if you have had any customers that made the same change. Thanks

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 the 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 # AM10303, 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.
