Low Pressure In One Tire! - Toyota Yaris Forums

bronsin · 07-11-2015, 06:38 AM

Even though I have tire pressure alert I check my tire pressures two or three times a month.

I find the pressure drops in the fall when temperatures drop also and air needs to be added.

But for the most part, three of my tires maintain 35 psi almost always while one tire will only hold 30 psi.

If I bring the pressure up to 35 by the next check its down to 30 again.

Yet it never falls below 30!

In 40 years of driving I never saw that. IF a tire has a leak it keeps on leaking until pressure is zero.

But not this one!

I'm having this issue ^^^^^ with the (now) left front tire on my '14. The dealer put 'lifetime nitrogen fill for the tires' on the PAC sticker that was taken off the price before the price I found on the internet. I wonder if this slow leak = re nitrogen, re the crappy and thin tires Toyota put on the car, or re some small road hazard. The TPMS eventually kicks in and trips the light, but IMO that should happen sooner than it does.

Sometimes a slow leak needs certain pressure to leak, until then it will stop leaking..

Is FAF approved for tire pressure sending units?

I don't know about that, but FAF and like competitors invalidate the tire warranty for at least one tire retailer.....Firestone.

You can't use FAF on wheels fitted with TPMS, because it will gunk the sensor and render it unusable.
