I am not sure what brand the tires currently on your trailer are, but the 27.13" height and 7.99" width of the Provider ST205/75R15 Radial Trailer Tire w/ 15" Vesper Black Mod Wheel - 5 on 4-1/2 - LR C # MX37FR you were looking at is standard for this size. Is it possible your tires are a 205/75R14? If that was the case that would explain the 1" height difference.

There shouldn't be an issue using these to replace your current tires, but since you mentioned they are 1" taller you will just need to measure from the top of your current tire to the bottom of the fender and make sure there is at least 3-1/2" clearance.

Lastly the # MX37FR has a wheel with the 5 on 4-1/2" bolt pattern, so you will want to verify that your hub has this same bolt pattern. You can do this by measuring your current wheels following the included help article.

If you find you have a different bolt pattern just let me know.

I included a video of the # MX37FR for you to take a look at.
