From what I am looking at, Kenda Tire, # AM10068, it has a width of 5.5 inches, 21.9 inches tall, and it has a capacity of 1,250 pounds at 105 psi. But it is a 5.30-12 size like you currently have on the trailer.

Another option is the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire, # AM10130. This tire is rated at 1,220 pounds at 65 psi and is 5.7 inches wide, 21.3 inches tall.

To go wider, you would need to move up to a 13 inch rim. Take a look at the Loadstar ST175/80D13 Bias Trailer Tire with 13 Inch White Wheel, # AM3S120. This combo is 6.6 inches wide and has is 24 inches tall. It has a capacity of 1,360 pounds at 50 psi.

You will have to make sure you have enough clearance on the trailer for the new size. The 13 inch listed above will be about 5/8 of an inch closer to the trailer side and 2 to 3 inches taller than a 5.30-12. Always inflate trailer tires to the maximum rated psi indicated on the tire for longest life and best performance.
