Slow puncture advice

richatha · 07-25-2018, 12:08 PM

So it would seem my car has a slow puncture on the rear passenger as the warning came back on even though I pumped it up yesterday evening.

Just wondering if run flats can be repaired and as the cars done 4,000 miles now do I need to replace both rears?

Sure it is not the valve? Get a jack. If it is the front then turn the wheel out. Full lock steering. Pump the tyre may be 1-2 psi more than you would. Use some fairy mixed with water to track down the leak. Pour some on the valve too.

Yes you can have it repaired. I had a Bridgecrap with a slow leak once. So slow it must have been there for 200 miles or so. The tyre internals were fine so it was plugged. The less you drive it on it while it has a leak the better chance you have of repair. So plug it asap if you can.

Unfortunately don't have a jack but will be getting someone ASAP to take a look at it I think as you say don't want it getting worse. I don't think it's the valve but will check with soap as you said!

Thanks

I had a slow puncture witj a nail in a rear tyre when my car had only done about the same mileage. If you drive on the tyre when flat it will be scrap and need replacing but it has never been driven on flat and it is in a repairable area some tyre places will repair it. I got mine done for £20.

In that case if you have someone who can drive the car forward slowly while you inspect the suspect tyre then that could work - use the soapy water or see if you can find the foreign object. A low profile jack and a plug kit would make a good investment.

Yes the longer you leave it the more you run the risk of a not so slow puncture and worse case a blow out on a motorway.

Check local smaller tyre fitters and firstly determine if they will fix it. Make sure it’s not deflated too much, if so pump it up. Get it to them and let them have a look at it. Might be a write off, but more likely it is repairable.

^^^ This - you may need to ring around a few places to find one that will repair a rft. Expect most national tyre firms to refuse to repair. If the puncture is away from the wall and you haven't driven on it flat you should be OK. The tyre fitter will check the integrity of the tyre - any sign of damage and it will be scrap and be aware that they may well not have a tyre in stock.

richatha · 07-26-2018, 02:09 AM

Thanks everyone I'm going to ring round a few places today and see if I can get someone to look at it and fix it if possible.

I'm making sure it's keeping air in too as when the warning is coming on I'm pumping it up pretty much straight away.

richatha · 07-26-2018, 03:17 AM

One more question. If I have to replace it am I better going for the exact same tyre as I've got on the other side or can I get something different?

Also does anyone know the tyre size of the 19" wheels as the mrs has the car at work so can't find out.

Jeff123 · 07-26-2018, 03:36 AM

I would just go for the same type of tyre, as most runflats are quite expensive anyway. The good thing is that if the tyre is knackered, you can still drive round for a day or so until they get one in stock.

Get her to take a photo of the side of the tyre and send it to you, assuming she is somewhere near the car.

I just had a puncture repaired on a run flat. Has to be on the tread and not side wall. And like already mentioned don't drive on it flat.

Wonder if BMW (and others) could work in conjunction with manufacturers of RFTs and come up with a system that gives an indication of RFT 'health' given it's a bit of a grey area. Maybe the TPMS readings used in conjunction with speed/distance traveled and tyre manufacturer data could come up with a formula that then posts a message on iDrive after running an RFT at reduced pressure. E.g a message on iDrive saying "Tyre x has n% reduced structural integrity".

Bridgestone must have done its own testing to come up with the statement "...allow continued operation even after a loss of some or all inflation pressure for up to 50 miles (80 km) at a maximum speed up to 50 mph (80 km/h.)".

richatha · 07-26-2018, 09:52 AM

Well down at the garage and it was this bugger

Luckily they've been able to repair it!

Thanks a lot for all your advice it certainly put my mind at ease

Hooded · 07-26-2018, 12:20 PM

Lucky ... it's only just inside the repairable zone

richatha · 12-22-2018, 03:33 AM

Another one strikes again!!!

God damn it another nail in the tyre today. Pressure sensor came on when heading to the shops. Got home and got the Mrs to drive the car forward to see what's going on and there she was!!!! Should hopefully be able to get repaired luckily it's the other wheel this time!

Jeff123 · 12-22-2018, 04:56 AM

That tyre looks pretty much at the end of its life to me.
