screw on the tire

How do you know if the tire is leaking? did you check your tire pressure and compare it to the other 3 tires? that's the best way to check it. Your TPMS monitor won't go on unless its around 23psi I think or 20psi. Also if you want to check if its actively leaking or not, get soapy water and run it through the puncture area to see if any air is leaking out.

 

then I don't think the nail went all the way through, if you do have a flat tire, check every week to see if the tire pressure changes when you compare the 3, if not, then its not punctured.

 

TPMS is triggered when PSI is 25% below minimum, in other words well into the dangerous level. It's like waiting until the smoke alarm sounds before attempting to put out a fire... too late.

Measure the PSI when cold (no driving for several hours). Then measure it again later (like the next morning). If it changed even just a small amount, you have a leak that must be dealt with.

I pulled a screw out of mine this spring. It was in pretty deep, requiring a tool to pull with. Fortunately, it didn't penetrate beyond the belt. No leak. No repair needed.

 

If it's holding air, you're fine. Everyone should periodically check tire pressure - every week or two - just to ensure they stay in the desired range. This will help maximize tread life and mpg.

 

I run my tires at 40/38 and have TPMS set at this point. I had a screw in my tire and it alarmed at 30 psi which is not a dangerous level. For those that run their tires at the Toyota recommded pressures in the mid-thirties then the TPMS alarm point will be in the dangerous range. Another good reason to run at higher pressures other than just mpg.

The TPMS is a nice safety feature but it is not a substitute for checking your tire pressures regularly as stated above.

 

you lose 2 psi every month, so checking every month is the ideal, but you can never be too cautious by checking it every week

 

Maybe YOU do but that certainly is not typical of everybody.

It took mine about 6 months to lose 2 PSI......and one tire didn't seem to lose any.

 

Most critical info is missing.
How long was the screw?

There is a big difference in 6 months from winter to summer vs summer to winter. You know, it has to do with thermodynamic law.

 

It may not be leaking. You may have lucked out. Check your pressure in that tire after the car has set overnight, then do the same a day later and if it is okay then, do the same thing a couple of days later until you can be sure it is not leaking. Looks like you lucked out. I have had the same thing happen to me a couple of times. Good luck.

 

Ditto. My OEM Toyo Proxes tires lose 1 PSI every two weeks (temperature compensated) like clock work, I'd say it is typical of the LRR tires. My previous standard tires on my Camry lose 1 PSI every four weeks.

 

That looks like it might have been very close to poking all the way through.
I would be a bit nervous, especially since it is over near the sidewall.

 

Maybe mark the inside of the rim near where it was, then keep any eye on that tire, monitor pressure frequently.

I've found one of our OEM's had a sort of cylindrical "bite" out of it, sort of like some sort of bolt was there, for a while, then flung off. It goes alarmingly deep. I was even contemplating doing a pre-emptive plug repair, having a kit and having done a couple of other repairs. But I can't bring myself to punch through a hole that's not leaking as yet. That was about a year back I noticed it, and so far all good.

 

No, this is too short to go through the tread in a brand new tire. Lucky, as this spot on a shoulder is considered not reparable by most tire shops.

 

Ahh,, its just a little Screw, not a big one. You did the right thing by soaping it down, watching for bubbles, and listing for the dreaded Hisssss.
Not to worry,, everyone gets "a little screwed" now n then!

 

Well, just regurgitating what I learned through my automotive program and through my tire pressure check every 6 months when I do my oil change. But whatever floats your boat, I'm not here to attack anyone. You can take this with a grain of salt , but good to know that not everyone has the same problem.
