TST, does temps and pressures. 6 sensors on the Prism, 4 on the toad. Moved it from our "B" after 80k miles to the new rig, added sensors for the toad. Saved our hides at least 3 times. I had always checked tire pressures every AM, but the 3 flats I got were while rolling down the road later in the day. Without TPMS would have been bad! The temperature monitoring feature even saved a problem. Travelling thru Blue Ridge Mountains, noticed increased tire temp in front wheel, just before breaks went soft! Stuck caliper! They are a "must have" in my book! ST
