Can 13 inch Trailer Wheel/Tire be Replaced with 14 inch Wheel/Tire

Question:

My 18 ft Chris Craft’s trailer was outfitted with 13” tires. Could I change over to a 14 or 15 without creating a problem for myself?

It's pretty common to increase the wheel diameter like you are wanting to do on your trailer. The big issue will be the amount of clearance your trailer fenders will have with the larger wheels. You want to have at least 1 inch from the inner sidewall of the tire and the trailer frame and at least 3 from top of tire to bottom of the fender.

You'd also need to make sure your current wheels have a 5 on 4-1/2 inch bolt pattern to fit a wheel/tire like the # AM32131. The tire size ST205/75R14 has an overall diameter of 26.3 inch and width of 8.1 inches.
