Question:
Thanks for your reply, Kyle. I guess radials are the way to go, but one will definitely pay for the privilege! You can order bias tires and rims by the dozen and they are practically disposable. But avoiding the stress of a blowout and hassle of changing a tire are priceless, right? These bias tires I have are M rated, so I was not exceeding their rating, but who knows. I am quite willing to go to a larger diameter tire, as well as doing the radial, I think the larger tire can only help. You mention N rated tires as being available in some larger size, but I do not see any on your site. Am I missing them? In your experience, how much larger a tire can I put on this trailer? I need to replace the fenders and their holder brackets as it is, so that is not an issue. The present hub and axle system provides a two inch clearance between the inside sidewall of the 4.80 tire and the trailer frame.

The load range C Provider ST175/80R13 Radial Trailer Tire # TTWTRTM1758013C has a speed rating of M, which is 81 mph; and there are tires with speed ratings of N, though not for 12 inch tires; for that the highest speed rating the 81 mph M-rated tire.
There are two things you can do in order to reduce blowouts, one of which is not exceed the speed rating, but the other is absolutely go to a radial trailer tire. These flex more and run cooler than bias trailer tires, so if you are using a bias tire that would be one reason why you are experiencing blowouts - they just aren't made for high-speed highway driving. That said, if you go faster than the speed rating you'll continue to get blowouts because the tires are going to get too hot.
In order to reduce blowouts, for a load range C radial tire with an 81 mph speed rating - the fastest for this size tire - you will need the Taskmaster 4.80R12 Radial Trailer Tire # TT48012C.
Adding this tire will help reduce blowouts so long as you stay below the speed rating. I have added links to video reviews for you to check out as well.
