Many times, trailer tires do not have a speed rating. The tires that we carry are rated for up to 65 miles per hour unless otherwise indicated on the tire sidewall. Since 185/80-12 is not a common trailer tire size, it would require going to a 13 inch wheel and you may or may not have clearance around the tire for the larger size.

There is a 145/80-12 trailer tire size that will be about a half inch wider than a 5.30x12. I have included a link to them for you to view and a link on trailer tire sizes.
