I am teaching a tire/brake lab this week and thought I would attach Good Year's aircraft tire care manual which addresses a lot of concerns we all have on tires.
A few highlights:
In respect to bias vs radial tires, bias tires have ply cords that wrap around the bead at a significant angle which allows for sidewall flex. Helps absorb energy from landings etc. through sidewall flex. Flex equals heat amongst other things and with Michigan roads we get a lot of flexing running down the road with our rigs. Radial tire plys around the bead are at 90 degrees which is why you see a different profile in the sidewall of these different tire types.
In aviation, we cant change from radial to bias and vice versa without manufacturer approval of the aircraft and the rim must be approved as well for the different type. But we can mix and match nose/mains.
Age isn't necessarily an indication of serviceability, condition is which means regular inspection. Spares should be inspected regularly. (Good Year recommends 30 days).
Good Year recommends jacking if stationary more than 30 days. Casing flat spotting which occurs when your trailer sits stationary is normal and can be worked out through movement or use-it's normal.
After install, wait 12 hours prior to use as the tire will stretch after inflated. Since most of us install our trailer tires immediately after purchase, check pressure.
For new installation tubed tires, air trapped between the tire and tube will work itself out, causing a decrease in tire pressure(mostly n/a for our trailers).

.
Hope this helps!
