(update bought Hankook tires)

Carlisle has some USA mfg tires that hold up OK. There was a phase 10 or 15 years ago they were blowing all the time. Discount tire replaced 12 of them for me one year.

Just bought a set of (cheap, like just over $100/tire for 275-40-20s) Hankooks for the wife's Charger. Only put the fronts on, still using the other 2 original tires for summer driving and burnouts!
So far they are super smooth, no louder than the PZeros and do great in the rain. They will not have the dry traction of the old tires, but they appear to be a good value thus far.

You hear a lot of this kind of "reasoning" along with the "china bombs" attacks. Just because a tire was poor many years ago it doesn't always follow that they will always be poor. I had a new hybrid trailer and lost a Carlisle tire to a blowout. I fought the company and they agreed to cover my cost of replacing 5 tires. I had to sign an agreement where I wouldn't trash the company. I have since changed trailers and had trouble with my Goodyear Marathons that were made in America. I replaced them with a set of Maxxis, that are not made in America, and they were great tires. Replacement time came and my dealer talked me into the new Carlisles. Told me that they were a new design and that the performance record was very good and that they stood behind them. I am on my third year and they are the best I have ever had. They have a speed rating of 80, run smoothly, haven't overheated and maintain air pressure. So, stay informed, continue to research and make the best decision for your situation. Closing the door on a product might not always be the best way to go. Things change.

The Marathons were problematic but mine were made in the US. That alone does not make a tire better. Maxxis are not made in the US and they continue to have great reviews. It is not the country where they are made, it is the attitude of the company who makes them. Usually, I will concede, moving to China is a cost cutting thing. If the company only wants to make money it will end there. Quality control can be maintained overseas as easily as it is done here. Keep an open mind and research.

Smaller wheels spin the bearings faster and those small 13 in tires seem to be the ones on small trailers seen along side the road.
I'll add m y2 cents to those who encouraged you to see if larger wheels and tougher tires will fit under the fenders. Also not the sell larger sizes of fenders at Tractor Supply and other places. As to changing trailer bed height, if you get larger wheels and tires measure and see if it is acceptable. Shouldn't change it much.
