Generally speaking, it is not a huge deal to upgrade one size (12" to 13") so long as you have clearance but the other thing to make note of is the surface area on the hub. If you have a 2,000 lb trailer axle then your hub is likely…

The 5.30-12 tires, being wider, are going to make more contact with the road. This means that the noise, and heat build up will be higher than a 4.80-12 tire but the rolling resistance will actually be less because the tire is larger diameter. The…

I do have an option for you but we currently do not have a standard trailer axle with a distance of 65-1/2" from the center of each spring seat. Instead, I recommend taking a look at the Timbren Axle-Less Trailer Suspension System part…
