One of the shortcomings of the off-brands is that it is hard to find a tire pressure chart for them. Rarely are they found online and the dealer may r may not have one either.
Not quite true.
NHTSA does do some random sample testing. I know because I have been involved in some of that testing.
But it costs money and who is going to pay?
I know that the majors do continual monitoring and testing in production and have dozens of machines running 24/7 in their plants trying to be sure that all tires comply. Recalls are unbelievably xpensive at multiple hundreds per tire so they really want to avoid recalls if at all possible. Its a lot cheeper to scrap a batch at the producing plant than to spend the hundreds of dollars per tire it costs to do a recall.
RE what load inflation to use for an "off brand". If you check the links in my signature you can look up the load & infl charts for a number of different manufacturers. You will note that almost all have identical numbers for load & inflation for the same size.
1. get your unit weighed at each corner when fully loaded.
2. Consult the charts to learn your minimum cold inflation requirement
3. Check the cold inflation before the start of each trip.
4. When inflating cold tires do not exceed the Max for the tire or the Max for the wheel.
