| If you're inflating them to the maximum pressure, make sure you are checking them cold, and not after driving on them.
My recommendation would be a few pounds under max just like on your car/truck.
A tires worst enemy is heat. The individual components of a tire (tread, belts, sidewall) all have a critical temperature at which they basically disintigrate. This happens rather abruptly in the form of tread seperation, sidewall "blow-out", etc.
Sometimes there are flaws in the construction of the tire that cause this to happen, but more often than not it's underinflation that does it. The sidewall flexes too much, which causes inside of the tire to heat up, and when it reaches that critical temperature the whole thing just flys apart.
This will all happen in a matter of seconds on the highway if you've hit a nail or something.
Overinflation is less likely to cause a problem until you hit something -- a pot hole, a rock, etc. Overinflation will cause unnecessary stress on your vehicle however, and your tires will wear out a lot faster.
Check the tread wear. Overinflated tires wear in the center and not on the edges, underinflated tires wear on the edges and not in the center.
And this is something that I will tell everyone who asks:
Don't waste your money buying cheap tires. This goes for your truck, your car, your boat trailer...
You're not saving any money in the long run.
Cheap tires wear out and need to be replaced long before good tires. Really cheap tires fail. If not for your own safety, consider your truck, your boat, and the other motorists around you who are going to have to try to avoid hitting both when you lose a tire at 65 MPH.
