another kind of question.... what about when i leave the trailer out there for an extended period of time. should i park the trailer/wheels on a board or something. a couple guys today told me that leaving them on the ground like that can make the tires go bad...

Time and just not moving them make them go bad. I can put a tire on a shelf and not move it for a while and that can ruin it.... Just move it around every now and then off the point it's been at and you'll be fine. Boards or different material won't help really except keeping it from the dirt. Your PSI level on the trailer tells you what the normal pressure is. The side of the tire is what the max pressure should not exceed for heavier loads.
Example: say your tire maxes out at 50 PSI and can hold 1200 pounds at 50 PSI. If you have a single axle trailer with two tires your threshold is 2400 pounds for boat and trailer those tires can support. Same theory with dual axles just multiply by 4 instead.
If your boat and trailer were heavier than 2400 pounds, you would need to step up in ply rating to hold more PSI and additional weight. Kinda like the reason you don't put low load range tires on a diesel. Cannot handle the load. Probably have you way to much info but hope it helps.

Do yourself and your rig a favor, get your wheels balanced. Pull the weights off your truck and feel it shake your teeth to pieces, that's what's happening back there whether you feel it or not.

Normally trailer tires fail for one of 3 reasons. Not enough load rating,time degradation and low air pressure. Answer to problem #1 get at least C and better yet D rates tires. #2 when one blows the other isn't far behind, replace all as a set. #3 set air pressure to max, cold

I agree I buy mine in set of three.
Every five years or less is my rule.
i have gone over 5 years twice and both resulted in tire blowouts.
$89 a tire on avg mount, balance, taxes, and fees.
I take my tires off and drop them off at a tire shop and pick them up after work.

I just got two of mine changed at delta world tire. They carry tow master I think. Now I just have to change the other 5 I just put the axle on jack stands and took in the dry rotted spare and the blown out tire. Dropped them off and picked up later. I will keep rotating my oldest tire to the spare until I get them all changed. I will never own another triple axle trailer....

I just found this online, and it also appears the tire co recommends running at Max PSI listed on tire.

Inflation
•Always inflate trailer tires to the maximum inflation indicated on the sidewall.
•Check inflation when the tires are cool and have not been exposed to the sun.
•If the tires are hot to the touch from operation, add three psi to the max inflation.
•Underinflation is the number one cause of trailer tire failure.

Does this make a difference on a small single axle trailer with smaller (4.8x12) tires? The guy at the tire shop said I'd be wasting my money to get them balanced.

wasting my money
Tires wear unevenly when they are out of balance and the worse it wears the more out of balance it gets. The wasting money is relative to how much you pull the trailer. Do you wear out tires or do they go bad from age first? If age is getting them then balancing isn't saving you anything but if they're wearing balancing could maybe double tire life. So if you hardly ever pull the trailer and its hauling junk it's probably not worth it.
