That's great input on tires.St trailer tires suck butt.
Put LT tires on it. In particular 235/85r16 Yokohama geolander ht tires. That tire has been extremely successful going bald before exploding while overloaded on oilfield trailers. I would get 30k miles out of a tire. Unheard of with an st tire.
Bearing and brakes are wear items for sure but it's like buying precision ujoints or spicer. I had my 5x4.5 trailer and it was a poor towing experience. Wore out inside shoulders on the tires with garbage carlisles. I would warranty a tire every trip it seemed. I was dancing on that fine line. It towed it but it struggled.
I can't get tires to last on my trailer.
I keep having broken belts in the tires.
So is that Yokohama an actual trailer tire or is that an automotive tire?
