tire pressure
Should the tires always be inflated to the maximum pressure that it says on the sidewall?

......To me, not worth the hassle with constant adjustments in pressure..
Only time I make any adjustment is when my TST system tells me my tires are not:-
Truck front - 45psi
Truck rear - 70 psi
Trailer (all 4) - 50psi
The Max sidewall pressures of those are 80psi/80psi/65psi respectively.
So no, I do NOT run at sidewall max pressure. These pressures are what the tire tables say are required to support the truck and fiver at each one's GVWR.
You MISUNDERSTAND THEN TAKE MY POST OUT OF CONTEXT.
My assumption was that the OP IS ASKING ABOUT THE TRAILER TIRE PRESSURE NOT THE TOW VEHICLE.
There are quite a few folks on this form that advocate setting the tire pressures ON THE TRAILER TO THE LOAD USING THE WEIGHT OF THE TRAILER AND TIRE PRESSURE CHARTS. THAT IS WHAT I AM TALKING ABOUT.
My point is most everyone runs their trailer NEAR, AT and some cases ABOVE the GVWR rating of the TRAILER.
It makes zero sense to put 48 PSI into a 50 PSI trailer tire if your load on the trailer is half or 3/4 of the tire capacity..
That is nitpicking and really serves no purpose..
You have more chance of BLOWING a tire since you are now LOWERING THE TIRE CAPACITY TO THE LOAD.
People come here and whine and complain all the time about blown tires, not to mention extremely quick to blame the tire manufacturer..
Why not TAKE ADVANTAGE OF THE EXTRA TIRE CAPACITY and fill it TO THE MAX SIDEWALL PRESSURE ON THE TRAILER.
It HAS worked for me very well, even ran those dreaded Carlisles that everyone here says are bad on several trailers with ZERO blowouts..
If I used these charts for my 10K flat bed utility trailer I would have to drop the pressure from 80 PSI to 40 PSI when empty then pump it up to the load pressure when I put a load on it..
Thats just stupid.
For your trailer there is no "gain" to be had by nitpicking the pressure..
