        Will 185r-80-13 tires replace d175-80-13 tires on a boat trailer? Thanks for any info.

        Probably but I would check with whoever mounts the tire on your rims.

        The 185 tire is slightly wider than the original 175 tire. This all comes down to how wide your wheel is. Most wheels can handle a range of different widths so unless the 175 was already approaching the maximum width of the wheel, the 185's will probably work.

        The only other difference is the 185 is a radial tire while the 175 is a diagonal belted tire.

        Again, I would just take your wheel to wherever you are getting the tires or getting them mounted and ask them.

        Here is a good article on the subject from Tire Rack. Their take passenger tires shouldn't be used on trailers.

        General Disclaimer

        Any advice given here is general in nature and is not necessarily valid for your given area. If in doubt check with your local codes enforcement department for what is required when doing electrical, plumbing or structural work on your house. Permits may or may not be required in your area and home owners may not be able to DIY some tasks. I have no way of knowing if you have the skills needed to complete the tasks you are asking about, when in doubt seek professional assistance.

        My advice may be worth exactly what you pay me for it. :-) For the record I did not stay in a Holiday Inn Express last night.

        typically, trailer tires are not stocked at tire stores. your trailer size and rating might not stay stocked at a trailer outlet. so there are two good reasons to buy a spare and mount it, then put it on a spare tire rack on your tow. another is, of course, they only blow on a Sunday afternoon or late Friday night when you are in the middle of nowhere.

        sig: if this is a new economy, how come they still want my old-fashioned money?
