I've always wondered whether it makes any difference as to whether you set the pressure when the trailer is laden or unladen. Presumably with a loaded trailer there is more weight and compression on the tyre resulting in an increased air pressure within? Or is the difference so negligible that it makes no odds?

Have now added some common tyre pressures to this page:

If they've a load index of 84 then their max capacity (@ 100kph) is 900kg and their max psi is 65. Ergo, you were bang on with your 60psi average - though I'm sure you were never in doubt!

I've often wondered myself Erin! I guess, theoretically, there could be a change in pressure, due to additional load, but it's likely compensated for by the deformation of the tire. Therefore the actual internal volume doesn't change (ergo pressure) as the tyre compensates for it.

Theoretically anyway! lol Doubtless there'll be someone along, far more astute than the pair of us, to correct us in a minute

Yes sir, the 5.00 x 10 denotes cross ply. If they said 145R10 then the 'R' would indicate radial.
