Tire replacement - Event Date: 18 Jan 2023

To be clear, If your asking, I'm not recommending Westlakes or Goodyears or Carlisles or any other particular brand. The brand I bought was Loadstar but I have no basis to recommend that brand over another. None.

My recommendation is to forget the brand. Ive taken a couple graduate level marketing courses. Buying anything by brand is a shortcut consumers afraid of making a mistake take when they don't have enough actual information to make an informed decision. Companies know that very well and play on those fears. So unless you have actual 3rd party data supporting the decision to buy one brand over another (not just a company's marketing BS or some guy who'd rather blame China for his blowout than check his tire pressure)   you're only doing that so you feel better. Which is fine if that's how you want to spend your money.

So my recommendation is to buy premounted ST tires and aluminum wheels on line from Eastern Trailer or wherever. Do the research to be sure that both the tires and wheels you buy have a load rating (in pounds not letters) around 25% above your axle rating. That choice, unlike brand choice, makes logical sense and has an actual engineering basis behind it.

Get wheels with a 5 x 4.5 bolt pattern. Get 15 inch wheels and tires and put on the lift kit if you don't it already.

Have the tires and wheels delivered to your home and put them on yourself. Good practice for when you have a flat later, and if it's time you can inspect your electric brakes and repack your bearings while you have your trailer jacked up.

Then sell your old tires and wheels on CL. Some guy who needs tires and wheels for an old boat or utility trailer he only uses for local towing will be happy to have them. Keep your new tires inflated to their rated pressure. Check them before starting out every morning when youre on the road.

That's my recommendation. Worked great for me doing it that way, and it's got an actual technical and financial basis justifying it.

If you dont have the time to do that (relatively minor) amount of homework then that's fine by me too, just buy by brand.

Wallyworld has that size in Carlisle for $99 they say:  https://www.walmart.com/ip/Carlisle-Radial-Trail-HD-ST225-75R15-113M-D-Trailer-Tire/55012157?wmlspartner=wlpa&selectedSellerId=0

Under inflation and hitting potholes and debris on the road can destroy even the very best made tires.  Moral of the story, monitor the tire pressure very carefully and and try not to hit road hazards on the highway.  No tire is indestructible.  

It isn't a question of "China bomb," but the quality of the components and manufacturing process.  The Carlisle 205R/15 D range tires are made in China.  I have only had one other brand of tires on either of our trailers:  Westlake.  They are of very poor quality.  I had problems inexplicable air leakage, rapid tread wear, and separation of the tire carcass from the tread rubber on a tire that had less than 3000 miles on it.  The rubber compounding is critical in tire quality.  Cheap rubber compounds do not last and are more frequently found on low end tires.  The tire construction is critical.  The bonding of the rubber, especially the tread rubber to the carcass is critical.  If it is not done correctly, you will get a dangerous tread separation.
