I have the TST 507 TPMS on my RV, and paired the four sensors for the trailer tires soon after taking delivery. Last week I lowered the spare tire for the first time to check the air pressure and saw the yellow valve cap with red symbol indicating installed TPMS. It may be common knowledge in the industry, but I did not know prior to this my spare tire had a sensor. It is now programed to the console.
