I am just wondering if anyone else is having this problem(which by the way did a search nothing showed up)
Anyways I was driving home this past sunday when my tire sensor light showed up. I checked all tires ..and a the passenger rear was down to 25psi, so i went to the gas station and bumped it back to 30psi. Monday morning checked the tire again and found that its down to 25 again...
so i used a 'fix a flat'..and made sure its at 30psi with the help of some air, and now i just went to check on it..its 28!!
Is it just my tire doesnt like 30?

If anyone had this problem..or could recommend any solutions id appreciate any insights on this.

PS..didnt the manual said 30psi suggested on the rear tires?

Fluctuations in air temperature will cause fluctuations in tire pressure. So will slow leaks. If the problem persists, visit your dealership or a tire shop and have them check out the tire.

can you be a little bit more specific??
like if the temperature dropped would the tire lose air
or is it the other way around??
thanks

The temperature of the air in the tire can make the pressure change without the tire losing any air. Hotter air expands... Colder air does the opposite. Always check and fill your tires when they are cold to avoid "false" readings.

Well I checked on the driver side door that front is 32psi and rear is 29psi. But I checked my tires and they are ~34psi. I guess that's bad huh?

Depends on your attitude and driving. My fronts are 36 and my rears are 34.

If your tire is losing air, it has something in it. Like a nail or a screw or some other foreign object that has pierced the inner liner. Get it fixed. Fix a flat very often doesn't especially if the foreign object remains in the tire.

To be properly repaired, the tire needs to be removed from the rim and patched from the inside. No other method retains the original speed rating of the tire, and no other method can be reasonably expected to last the remaining life of the tire without issues. Plugs and fix a flat are the worst things you can do to a tire.

Absolutely. I tried that fix-a-flat crap once and all I got for my troubles was a thunking noise in the tire when the goo solidified without plugging anything up and a wasted day/tire.

Check your tires every morning, before you drive, for at least 4 days in a row. They should all be consistent. If one tire is steadily loosing air, then you have a leak.

fix a flat worked on my huffy back in the day. for about a minute.

tire shops can check for leaks for you. But, if you want to check for yourself.

inflate the tire.
remove the tire.
put it in a bucket of water. or, get it wet some how.
look for bubbles.

if you find none you are probibly in the clear.

keep an eye on your tire pressure over time.

good luck.

i've been having the same problem w/ the front passenger side tire i was at toyota today and they told me that there is nothing wrong w/ the tire or sensor and that maybe i hit a pothole or something but every week just that tire needs air

peace

If you don't have a nail in the tire and it loses air every week, the rim is cracked. That is a MUST fix. FWIW, a cracked rim on the rear of a Supra makes a thumping noise at about 130 mph.

Fix a flat sucks. Also it can be dangerous, plugging up a valve core so when someone tries to properly repair the tire and lets the air out, the tire is still pressurized when they go to break the bead and the sudden deflation can injure the person fixing the tire. When you take your car to the tire shop, be sure to tell them you put that junk in there.
Also it makes a big mess all over the floor when you break a tire down.

Don't use fix-a-flat.. that stuff's for emergencies only. You can't ride on it for a long time.

Take off the tire and spray it with soapy water. You'll see where the leak is. It may just be the valve stem.

Unlucky me, I had a screw embedded in my 2 month old Avon Tech M550.

yeah i've had a valve stem leak before, and a nail that was still embedded in my tire. both leaked slowly.

an increase in temperature will cause an increase in pressure. and vice versa.

Thanks for all the info..I went to a local shop and told the guy that I think my passenger rear tire is leaking air, he asked me what was the pressure on my tires, i said it was 32F & 30R...he basically told me that the recommended psi is atleast 40, so he had me increase the psi and told me that its not necessarily i have a leak and that its just a matter of the temperature drop over this past weekend (it was like 53), a pot hole that i might have hit that triggered the tire sensor...and just plain potenzas is not a very good tire were all coincidence.
Anyways keeping an eye on my tire and hopefully nothing is wrong. I like a new set of tires but I dont like the cost.

Uh. If you're rolling on the stock tires, the recommended PSI is 32/28.

40 is too high.

40 is too high and there is no sensor inside that tire. New tire shop for you.

32/29. Live it. Love it. Believe it.
