Thank you for the photo of your tire in size 155SR13 from your 1992 Coleman Sequoia pop-up camper trailer.

Trailers should only be fitted with ST-type (special trailer) tires, not passenger car tires which are made differently. It appears that someone installed vehicle tires on your trailer. You will definitely want to install the appropriate ST-type trailer tires.

The tire size nearest to yours that we carry is a ST175/80-13 size like those shown on the linked page. These tires are 20mm (about 3/4-inch) wider than yours so you will need to check the trailer wheel well to see if there is enough clearance for this wider tire. Its overall diameter will be just over 24-inches when mounted and inflated.

We offer ST175/80-13 tires in several load ranges, B, C and D, and also in both bias ply and radial designs. Speed ratings vary too.

Let's say you want a radial tire in Load Range C (1360-lbs at 50-psi) that will do well at highway speeds. The Taskmaster # TTWTRTM1758013C would then be a good choice since it is rated for speeds up to 81-mph. You may care to have a look at the two linked articles on trailer tires.

All trailer tires should always be inflated to their maximum psi pressure that is noted on the tire sidewall. Never under- or over-inflate a trailer tire.
