The spare tire!!! Who'd have thunk it?

The tire pressure indicator on my Lexus daily driver dash has been lit for awhile even though I know the pressures are all OK. Checked it many times, and figured that one of the sensors had gone bad.

Stopped off at the Costco tire center and they said it could be the spare (which if a full-size tire, like mine, has a sensor too)! That turned out to be it!!!!!!!!!!

No need to spend $60 to replace one, or to get out the electrical tape to cover that idiot light. :fat:
 
Mark - what was the pressure of that spare tire? Usually they're set to higher psi than the road tires. I wondered what psi the TPMS actually caught.

Thanks.

Hey Tom:
I never heard what it was... as they have an automatic filling device (that I only watched). Truth is that I may not have checked this pressure for several years!
 
Mark, I had the same thing happen with my Rav4. I drove around for over a year thinking that I had a bad tpms on one of my wheels until I needed my spare one day, then I figured it out really fast.

Funny too, Walt, that THAT tire was staring you in the face the entire time (being on the back on the Rav4)! :wink-new: Mine was hiding the trunk. :cool:
 
When the weather changed,I had a warning from one of my road tires. I checked and adjusted all pressures and not wanting to climb under my Rover I let the spare go. Next day i get the warning bing and a reading that my spare tire was low.
 
Mark, I have since quit keeping the cover on my spare; makes it easier to check the actual air pressure when I check my other tires.
 
I envy you guys with a TPMS that tells you *which* tire is low! Many of those systems just say "tire pressure low" - and leave you to figure out which one it is.

Tom, imagine how I felt sitting on the side of the road with a flat spare when I was trying to change a flat.

My new truck tells me which tire is low, if a tire gets low a warning icon come up on the ins. panel. With the tires on this truck costing $220.00 each, that's nice feature. PJ
