Symptoms of tyre puncture in tubeless tyres
Am having a strange problem as to the ways to detect whether your tyre is punctured incase of a tubeless tyre.Now that may sound silly :eek: but let me explain.
For the last 4-5 days,am guessing the left rear tyre is punctured although not visible.The reason is when I try to turn left,the steering doesnt want to turn and needs a bit more of a force.
On Sunday,I had checked/filled all the tyres at 33psi.The very next day,I again checked and the left rear had come down to 20.I again filled it up to 33 but the tyre shop insisted there was no puncture(from glance though).
Can you please help me out?Also,how would you normally know a tyre puncture in tubeless unless its abs flat?
I don't think this is posted in the correct section. Anyway, since your tyre is losing, 13 PSI per day, and no puncture is visible, you wheel-rim might be bent or (if not alloy) corroded at the seams.
However, the only way to be sure is to dismount the tyre and immerse it into water.
Symptom of puncture: tyre goes flat!
... And it can do so slowly, possibly because what ever made the hole is still in the hole.
But yes, it can also be a damaged rim, or just that there is a problem with the seal.
As it happens, I too have such a problem, had for ages, and have just remembered to mention it this time on taking the car for service. Mine is on a front wheel, and, even before I can see that it has gone down. the steering will become heavy.
Thanks a lot Vipul and Thad. My car is anyway going for a service and will tell them to check it :)
What I have observed is that if you need to go for air refilling daily - then its surely a puncture.
With tubeless, you refilling frequency is more like once a month.
I have never had totally flat tyre with a tubeless. Its always been a slow deflation.
Yes. One can have a nail in a tyre and have only a slow puncture. Then maybe, one day, the nail gets moved, or driven out of the hole and fffffffffffph! the puncture is not slow any more!
I know that tyre pressures should be checked once a week, but very, very bad at doing so. Because we do a very low mileage in a diesel car we only need to buy fuel about once a month or so, and then we go for air also. Normally we find that three tyres just need a little, and one tyre needs a lot.
I'm also aware that it is very bad for a tyre to drive with very low pressure, and that fuel consumption gets worse too.
I know all things, and I should practice them.
What can I say? I am like this only? <Blush> ;)
I had the same issue with one of my rear tyres. I had rusted rims.
Most likely it is a puncture. I had this in two different cars with tubeless tires. The pressure will go down to 20-22 psi within a few days of filling/checking the air. The first time it happened, I drove for like a month - every week checking/filling air before realising that this was not good. I called up my tire fellow and he confirmed it was a puncture.
What happens is that there is a slow leakage of air and the shape of the tire deforms somewhat around the nail effectively sealing it and then the pressure stays at 20-22 psi. It is very unlikely for any tubeless tire to immediately deflate on getting pierced by a nail or similar object. Possibly it will go flat overnight or if by chance (it is unlikely since the tire's lower pressure enables itself to 'clamp' around the nail) the nail gets pushed out.
There is no need to even take the tire off the rim. Most tire shops have the plug/solution to fix it cold and they do it in like 10 minutes with a pair of pliers. It is a bit of a messy job though.
I now will never ever buy a car without tubeless tires. No more tire changing ever...:D
what qualifies as a puncture?
my rear left wheel keep loosing 4 to 6 psi in 2 weeks time.
am running tubeless on stock steel rims.
the remaining 3 wheels stay at 30 psi over 2 week but one comes to 26 / 25 psi.
no puncture found and rim too seems fine. meaning no rust of dents. i had the tire removed and check the rim.
What else could be the problem?
Thanks a lot everyone for helpin me out with the puncture thing :)
Am still driving with the puncture but hope to fix it this Sat(if it doesnt get flat earlier)
Another possibility is a leaking valve. I sugest pump up to say 35psi and then immerse in water. The culprit is sure to show up.
Get the tyre checked. Its a puncture that is not visible otherwise. Happens all the time :)
