Broken down. Advice needed
Discussion
I hit a pothole 20 miles ago and I am really thought damn is that another low profile tyre needed?
I’m currently in a petrol station and I am down to 15 psi on that tire. I have put more air in and I am keeping an eye on the level. At the moment it seems to be holding steady, but clearly I have not moved anywhere for a while.
I attach a photo of the tyre cap with the end blown off, presumably by the force of the impact to the tiye earlier.
My question is, is it possible to hit a pothole, have some deflation yet not have an obvious puncture? I cannot see any bulges on the side wall either on the outside or the inside.
Many thanks

I hit a pot hole hard on the way to meet my wife. My kids described coming out of the hole as making the car fly. It was brutal. I lost 20 psi instantly and assumed the rest was going soon after.. But, after filling the tyre up, it kept pressure.
The next issue the wheel was now causing the steering to vibrate. Assuming it destroyed the wheel, I took it to be checked out. They found it to be with in spec and showed me the missing weights that had come off in the "Accident".
For size reference, this was my Cayenne so not a small/light car.

I have never seen a tyre valve blow out the cap so I suspect that might just be coincidence.
As for the air loss then yes you can lose air and the bead stay intact - but its rare.
Its more likely you have cracked the wheel on the inside rim.
How far left to drive?
If not far stick 40-45psi in it and head home.
If 100s miles maybe consider putting your spare on.

I did get to where I was going. Thanks for the support on here.
The car is an 07 Quattroporte so no spare available. I called the AA to be safe. They couldn’t find any bulges, cracks or leaks from the rim or the valve. And the tyre was holding pressure.
I’ve just driven 80 miles and there was no loss in pressure since I added some air about 2-3 hours ago.
So I can only guess that the pothole broke the bead (where the tyre meets the alloy) momentarily and I lost almost 20 psi in that moment. I had not realised that this was possible.
Anyway it’s good to have arrived safely and I’m not still waiting for a transporter that’s due to arrive in the early hours, so this oddly feels like a ‘result ‘. Let’s see what the tyre pressure is in the morning.

A few months ago I hit a kerb and, after arriving home a couple of miles later, saw that the tyre was almost totally flat. It was late, dark and snowing, so I squirted a can of tyre seal and reinflated. Next morning took it to a tyre place and got them to take the wheel off and check, and they said there was no sign of any wheel or tyre damage. Being paranoid, next time I took the car into the garage I also got them to take off the wheel and check, and they also said all was fine. I've done about 2000 miles since and have kept an eye on the pressure and it only loses about 2-3 psi every few weeks.

Wheels are left buckled ...Only answer is new wheel.
It's also possible that the wheel may have cracked.Depending on your budget, slightly buckled wheels can be straightened and cracked rims can be welded - there are companies who specialise in this sort of work - so you may not need to resort to purchasing a new wheel.
You may be able to claim against the local Highways Authority for the damage caused, if you can identify the pothole to them.
Both your loss of pressure & the end of the cap missing COULD just be coincidental.
Unless you checked both immediately before hand they could have both been like that for some time and you only now know it due to checking.
Even with the end off the cap (which is only really a dust cap) the tyre should be capable of holding pressure.
Yes, I do know that valves can leak before anyone jumps down my throat, hence why I used the word SHOULD.

What was the tyre pressure of that tyre just before you hit the hole?
I checked the tyre pressures at lunchtime yesterday and the tyre in question was 32psi then. Around 15psi after pothole.I blew the tyre up to 37psi the garage and it held pressure during the next 80 miles. It was 36psi this morning, but the loss in 1 psi might be due to the cold tyres this morning.
I thought that a cracked alloy would most likely not hold pressure like this?

The loss of 1 psi will be cold versus hot. My tyres gain 6-8 psi with 15 laps from cold on a track day. You have just done the reverse, IFSWIM.I blew the tyre up to 37psi the garage and it held pressure during the next 80 miles. It was 36psi this morning, but the loss in 1 psi might be due to the cold tyres this morning.
