How do I choose a good trailer tire?

Question

We have 2 trailers- a popup & a covered hauling.  They both need spares.  The popup takes a 4.80-8, but the one I found, made in China, warns not to exceed 55 MPH.  It's a 2-ply tubeless which runs for $30-35 at Harbor Freight.  

The hauling trailer calls for a 4.80-12, & I found online at Tractor Supply Co for $75-80.  

Is it common for them not to be run over 55 MPH?  Or is that b/c it's made in China?  

Any positive suggestions of where to find them is appreciated.  Thanks, -Fuzzy

The 55  mph speed limit is probably an insurance company recommendation to the manufacturer to avoid liability issues should the tire disintegrate.  Tires also have a speed rating (along with a load capacity rating).  I wouldn't take a trailer to 90 or 120 mph even though the tires may by rated for that speed..

I look for the load capacity on the tire (more important that speed rating for my application).  My trailer can gross up to 2990 lbs.  So (with two wheels) I need tires that can carry 1500 lbs each.  2-ply tires are light duty tires.  If you can find 4-ply, it would be better (but will cost more).  Of course your 12" tires will cost more than 8" tires.  I use 6-ply rated tires on my trailer.

Find your local trailer dealer or sales and get the best info. Have them suggest, and then shop for better price (than what they offer)
