Well that's Tyre-ing...

Oh my well that's a good place to begin the day...

It's like Sophie's choice but with BF Goodrich's... To pull or not to pull that's the question... Leave it in and it could get worse, take it out and it could get worse... Rolling Eyes

How did that little thing manage to slot straight down the sipe and not just get flicked out of the way by the tread block...

I guess the real question is? In the Forum's experience and assuming that the screw has penetrated through the tyre. Will this be salvageable with a plug?

I believe legally a tyre repair can only be effected in the middle three quarters of the tread.

Yours looks like it might be outside that area, however, without measuring I couldn't be certain.

There is also the possibility that it is a really short roofing type self tapper and may not have gone past the tread depth.

Good luck in whatever choice you make regarding leaving or removing. 1995 300 Tdi Epsom Green - It's a keeper.

I wouldn't drive about with that left in, certainly not on the front.

I would unscrew it, if the air follows fit the spare and either get it plugged if a reputable tyre dealer will do this, or fit a tube. I have extracted screws from BFGs which have been longer that I thought possible without air loss.

It is a constant source of mystery to me how screws penetrate tyres since they lie flat on the road, yet always the point seems to penetrate directly into the tyre. How does this happen?

I'm with blackwolf, remove and see if any air come out. It may create a puncture that isn't there if you leave it in Thumbs Up (unless it has in fact already gone though) 2002 90 Td5 Station Wagon

This is after all why you carry a spare.

That's such a pain, isn't it? A tiny part of an otherwise perfectly good tyre.

I had a similar situation at a filling station in Orkney once, on the VW type 2. The previous owner had fitted chrome minilites and big tyres. Looked really good. Noticed a bit of metal in the tyre while filling the tank, started to prise it out, and "hissss". Sh*t! 5.15pm on a Saturday afternoon. Luckily I was 50 yards from a tyre repair shop. I tapped the thing back in and took it to the shop for a repair. Turned out it was a long fencing staple.

But the strangest one was in Glasgow, driving along and 'bang', pretty explosive flat tyre.... Changed to the spare, and I could see this large and strangely shaped metal thing stuck in the tyre. Turned out that was actually what was left of a small Stilson wrench! The handle had managed to penetrate the tyre. I can only imagine it got stuck in a rut or hole in the road or something like that and had nowhere else to go. There was fully 4 or 5 inches of it inside the tyre, bent back by the wheel rim - and that was in a 30mph zone.

Hope you get sorted easily. Donald

Worth remembering that punctures are the complete opposite of stab wounds. One should be removed, one should not. Thumbs Up

Ha Tuesday morning roulette... place you bets folks... Round and around it goes when it punctures no-body knows... Rolling Eyes Rolling Eyes

Well here you go... No Pssssshhhhhttt but the tip of the screw looks mightily shiney, wonder what that has been rubbing against?!?!

The good news is that the "Spit Test" came back negative for bubbles, so take from that what you will... Rolling Eyes

Good news, would also do a fairy liquid test to be sure.

Just had two nails in my VW Golf's tyre. Costco said they were too close to repair (but another shop might do it)
Given the cost of repairing two punctures is practically half the cost of a tyre, I just got a new tyre Big Cry

That doesn't look long enough to penetrate deep enough.

BFG's have a lot of Ply's and banding in them, a lesser tyre would likely have gave you a puncture.
Unfortunately when I had issues it was a cut and not a hole, and you can bet it'll be the sidewall or outer tread shoulder and not th emiddle of the tread.

Although it sounds a bit Heath Robinson, I'd check for any leaks yet again to be sure.
If that is a positive outcome make sure it's thoroughly dry and I'd fill it with a tiny bit of black silicone.
Otherwise, come MOT time, even thought it's perfectly okay it might get probed and failed even though there is no problem with it.
They often don't grasp the concept that these tyre's are very very thick and have multiple wall reinforced treads and judge it by standard car tyre standards.

If the outcome of a second leak test works out I'd say a lucky escape. Thumbs Up Watts ÷ Volts = Amps.
Amps X Volts = Watts

Yes indeed good news. I will of course keep a very close eye on the tyre for many days to come. Good idea about the silicone...!

Not such a bad start to the day after all... what a relief!

Don't know whether you can still buy it, but you used to be able to get the black rubber solution/glue that was used to seal the rubber plugs for DIY puncture repairs.
I would use this in preference to silicone as it should give a more robust seal to the hole.
