Tire Pressure

Regarding air stem material - is anyone putting the sensors on the rubber stems that come on the wheels? I talked to the "guru" at Camping World and he says replacing the stems isn't necessary as the sensors are only 1/2oz ea. I'd like to save the $ and time of replacing the stems but not if that buys me a bigger problem later...

Tireminder makes two sensors - one for brass and steel stems and one for aluminum like the newer cars have with built in TPMS. It has to do with electrolysis and corrosion. The standard sensors are brass threads and will corrode on an aluminum stem, so they make an all plastic sensor for aluminum stems.

Brass threaded sensors work fine on aluminum stems if you coat the stem with dielectric grease or anti-seize first.

Or you can order the plastic ones that are the same price I believe. On my Jeep I use deflaters, standard caps and the tireminders so I really don't want to grease them up, but in reality I use the brass on my aluminum. They don't stay on there long enough to worry about.

.there is one called Tire Minder on sale that is priced reasonably but it is stating for brass/steel rims...

We have the Tireminder TM66 and I gave one to my daughter. So far so good. I've had 1 bad sensor out of 12 (8 MH + 4 toad), and another that I broke the battery compartment. They send you batteries every year and they need them every year.

Read these replies carefully. Will reconsider.

Our TST TPMS has alerted us to a failed wheel bearing and a stuck brake caliper on our toad and a slow leak from wood screw in a rear coach tire, all occurring while under way. Would your morning pressure check have caught those incidents? There's good reason they've been mandated on all light (under 10K pounds) road vehicles for the past 10 years by the TREAD Act.

I recently replaced all 10 of my PP sensors (after 10 years) for $250 direct from PP. I do loosen the sensors when not going to use for a couple months.

First time one saves your azz you'll believe.

Odessa Texas, 105 degrees, we get a warning of an over temp on a front tire. we slowed and ran until we found a rest area. took a nap until the tire cooled off, had we not gotten a warning we may have caused a blow out and all that goes with it.

My most concern is heat.. that is why most tires fail, that one time I feel paid for my set of TST monitoring system.

We have the TireMinder A1A for all 10 tires on the ground. The sensors come in two different materials based on the valve stem material - not the wheel material. This is to prevent electric corrosion from dissimilar metals. We've been very happy with the system and it saved us a lot of damage from a road hazard incident.
