Pressures for LT E Tires

There is an industry-wide procedure for setting the recommended inflation pressures for your new tires. It’s very basic. The Original Equipment tires are the benchmark for all subsequent replacements. So, an experienced installer will ensure that the replacements are compatible with the OE wheels and that new valve stems will support the increased inflation pressures. The replacement tires, at the very minimum, MUST provide a load capacity - via inflation - equal to what the OE tires provided at the vehicle manufacturer’s recommended inflation pressures found on the vehicle tire placard, certification label and in the vehicle owner’s manual. Inflation pressures between recommended and tire sidewall max are optional.

NHTSA allows the use of an auxiliary tire placard to describe such replacement tires. The new tire size and it’s recommended cold inflation pressures should be depicted on such placard and it should be affixed adjacent to the OE placard. Notations should also be made in the vehicle owner’s manual.

Note: Inflation to the load carried is not a safe or acceptable procedure. Have you ever seen a motorized vehicle tire placard that didn’t provide some percentage of load capacity reserves for the GVWR?

So, if you want to inflate your tires like the lawyers want you too, then listen to FastEagle or CALandLIN or whatever screen name he is currently using. He just wants to sell you more ST tires.

Now, if you want to do it how the tire manufacturers suggest, get your axles weighed and set the tire pressure by the appropriate pressure/weight chart provided by the company that built the tires. It is advisable to add an additional 5psi for an adequate safety margin.
