Question:

I have 155 80r 13 size tires on my trailer and can't find them. What is a bigger size that would work?

I did some research on tire sizes and the difference between a 155/80R13 tire and a larger 175/80R13 is not significant.

The 175/80R13 has a width of 7 inches and an overall outer diameter when fully inflated of 24.1 inches. This tire size would be .8 inches wider and 1.3 inches bigger/taller than your current 155/80R13 tires. Because the wheel rotates on the axle, the overall diameter will be split so the actual change will be .65 inches.

I would check to see if you have 3-4 inches of clearance between these possible new tire dimensions and the trailer and it's components. If you do, I recommend something like the Karrier ST175/80R13 Radial Trailer Tire, Item # AM10210. The Karrier fits 13 inch wheels, has a maximum load capacity of 1,610-lbs at 65 psi, and a maximum speed of 81 mph.

If you are interested in a tire and wheel combination, I recommend something like the Karrier ST175/80R13 Radial Trailer Tire with 13 inch Wheel, Item # AM31985. This tire and wheel combo fits a 5 on 4-1/2 bolt pattern,
has a maximum load capacity of 1,610-lbs at 65 psi, and maximum speed of 81 mph.

Before making any changes, make sure everything will fit your trailer and have plenty of clearance. I have also attached some articles and videos about tires and wheels that will help with your project.
