Question:

I just purchased a new trailer. The tire size is ST225/75R15. The wheels are 5 inches in width. Is this enough rim width?

For a wheel that is 5 inches in width and 15 inches in diameter you would want tires that are size ST205/75-15.

For the tire size ST225/75R15 you listed you would want a rim that is from 6-7 inches in width.

I attached a department page that has all of our tires that are that size. I also attached a page on trailer tire sizing that has a chart that show what tire sizes go with the different rim sizes.
