Proper Tire Presure

There are at least 100 topics on this. It has to do with the weight on each axle and tire . . . Do a search

Do NOT use the max pressure molded into the sidewall. That's the maximum the tire can take without blowing up (with a safety factor, of course). You need to weigh the load on the tires (when typically loaded for a trip), then consult the tire manufacturer's load/pressure chart.

As an example, the tires on my Kia minivan are rated to 45 psi by the molded # on the sidewall. The vehicle manufacturer recommends 34 in the front and 38 in the back. With our typical load (me, DW and our two Labradors) the weighbridge numbers suggest 31 front and 35 rear. The Toyos I have on the van are at about 55,000 miles (van has 120K) and are still in good shape, using those numbers.

Both of the above quotes are IMO WRONG for ST tires which is what was asked about. While using pressures based on load inflation for normal vehicles has merit, tires on trailers and especially ST tires should be inflated to the max pressure listed on the sidewall as almost all of the other posts in this thread so far have recommended.

X2! Thank you Larry for clarifying this. ST tires and car tires are two different animals altogether.
