How to Upgrade Trailer with 45 MPH Speed Rating for Highway Speeds

Question:

I have a small utility trailer from Harbor Freight or Northern Tool and Equipment, I forget which, that is rated to 45mph. I need to be able to take this on the highway, loaded with a few hundred pounds of equipment, and Id like to upgrade the trailer to be safe at highway speeds. What do I need?

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 good to go! I will say that if your trailer itself has the rating stamped on the frame then you would need to contact the manufacturer to make sure that the rest of the components on the trailer can handle the faster speed.

If you let me know what size tire you currently have and what your wheel bolt pattern is, if you are wanting to also replace your wheels, and I can make a recommendation for you.

Question:

Currently the trailer should have 4.80-12 tires on a 12 wheel with a 4x4 bolt pattern.

If that is the case then I recommend going with the Taskmaster # TA89RR. This is a 4.80-12 tire which is on a 12" wheel that has a 4 on 4" bolt pattern. The load range is C (990 lbs at 90 psi) and it has an 81 mph speed rating.

I have attached a review video for you to check out.
