Typically on a trailer the only part that has a speed rating is the tire itself, though you will need to contact the manufacturer of the trailer to confirm this.

Based on the tag shown in your picture your trailer uses a 4.80-12 so for a high speed replacement we have the Taskmaster 4.80R12 Radial Trailer Tire - Load Range C # TT48012C which will be an exact replacement, but has an 81 MPH speed rating.

Should you find that the hub has a speed rating, just let me know the bearing combination and I would be happy to check if there is a compatible higher rated hub though harbor freight trailers typically use a very odd bearing combination.

I included a video of the # TT48012C for you to take a look at.

I would be happy to help! We do not have an axle that has the 56-1/2" hub face to hub face measurement your current axle has, but we do have an axle-less option that will work. I recommend the Timbren Axle-less # ASR2000S01 which have a 2000lb rating which is plenty for the 1195lb capacity of your trailer. This option bolts directly to the frame of your trailer and replaces your current leaf spring suspension with progressive rate AEON main springs that do a fantastic job of of absorbing road shock giving you quite the upgrade of your current suspension. I included videos of the products mentioned for you to take a look at.

The only trailer component that determines the speed rating of the trailer is the tires. All you have to do is simply replace your current tires with one that is rated for highway use, like the Kenda Loadstar #AM3S120 that you referenced, and you are…

From my research on the Harbor Freight 4x8 folding trailer uses 4.80-12 tires on a 12 inch wheel for the 1195 lb capacity trailer and a 5.30-12 for the 1720 lbs capacity trailer. It is a good idea to check your existing tires to see which size they…

Yes, the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire #AM10140 referenced in your question will fit the same 12 inch wheel with a 4 inch width that your existing 4.80-12 size tires are mounted to. Just note that the ST145/R12 tire will be…

Yes, a 5.30 x 12 tire will fit the same rim as a 4.80 x 12 tire. Both tire sizes fit on a 4 inch wide rim. There are a couple of things to consider when changing tire sizes. First, the larger 5.30 will be approximately 1.4 inches taller than the 4.80…

Answer 8

From what I could find, the Harbor Freight trailers do say not to exceed 45 miles per hour in the owners manual. That being said, the tires they use are not rated very high and may be the limiting factor. The trailer you have looks to use a 5 on 4…

The first problem is that you are running lower air pressure than what the tire is rated for. Trailer tires should ALWAYS be inflated to the maximum air pressure as indicated on the tire. The reason is that trailer tires are constructed with a…

It sounds like you are looking at a tire similar to the Westlake ST205/75R14 Radial Trailer Tire # 274-000012. The speed rating you mention of "L" is a max of 75 mph. If tires have this higher speed rating, they are labeled L or M (81 mph).…

Answer 11

You are correct, the 5.30x12 is the SAE nomenclature, while the 145/80-12 is the closest metric equivalent. The two are approximately the same size with the 5.3x12 being about a tenth of an inch narrower and a quarter of an inch taller than the…

Answer 12

For a trailer you have to use wheels specifically designed for trailer. Passenger vehicle wheels and tires are not rated for trailer so they should not be used. Best option we have would be the part #A225R645WM which is a 225/75-15 radial tire…
