Hi, just noticed today that I have a screw seemingly lodged into the valley of my tyre tread.  It’s a Pirelli scorpion verde...do I ignore it, take it to a repair shop, or unscrew it hoping it will seal?

the vehicle is a kodiaq...

The longer you leave it, the bigger it will make the hole until it comes out. It's repairable so just get it done but don't try to remove it yourself as it will deflate.

 

BTW Welcome to the forum

Yeah needs plugged. Take it to a tyre place.

 

nice and easy fix

I can plug that quicker than the air would leak out including reaming out the hole with a battery drill & rotary rasp bit.

 

Well the garagiste could as he has done loads and is confident and a show off!

 

I would take a lot longer faffing around to be sure of a good job & then re-inflate it.

Is there a process I can at least describe to the garage in how they should go about repairing it? Struggling to find anything online.  You say “plug” - what does this mean?

cheers!

Anyone that repairs/replaces tyres should easily know how to plug a tyre.

Oils this simple even on the scorpion tyres which self seal with gunk?

That will be a new tyre.

A lot more searching online seems to say that “mushroom type repair patch” is fine and just needs to gunk scraped away from the affected area.  Time to go see!

Plug is inserted from inside (so have to take tyre off rim) and had a flattish head so it cannot push out through the hole (roughly shape of a mushroom, but much smaller)

 

But on a self seal tyre there is a layer of goo inside so don't have a dry flat surface to bond it onto, unless a small area can be cleaned up

 

 

take it to a tyre place they will remove tyre, remove screw and plug from the inside out. Similar idea to fixing a bicycle tyre as a child

 

will cost £5-10

 

my local place is a fiver but i’d imagine mainstream tyre places will be substantially more expensive than a fiver

These are run flat tyres though. They haven't just had some gunk squirted in them. The design of a tyre incorporates a self sealing layer inside the tyre as part of its construction so I am not sure if a repair would be suitable.

The plugs I am speaking of are fitted from the outside, on a front axle or with enough wheelarch space on the rear the wheel can remain on the vehicle, no jacking up required.

 

They are a roadside repair kit, a small pouch with hand tools, the plugs and often some vulcanising compound, were banned for years in the UK but thanks to the EU no longer, the UK describe them as a temporary emergency repair, here in Europe within defined parameters they are and have always been a permanent repair, ideal for a puncture like the one shown.

 

It is not agood idea to go into a tyre fitting shop and tell them how to do the repair, they should know and should propose the relevant repair, I would feel more secure with an internal mushroom plug repair, with a plug I keep a close eye on it and the tyre pressure for a good while.

I've used those before when touring and the results have been mixed. Tyre off, inside prepared with plug patch repair will safely last the life of the tyre and is only around £15

Agreed.

Well I never got that from the original post

 

are these a new sort of RFT unlike bmw that just has harder sidewalls?

I know a lot of places will not plug a bmw RFT as they cannot say how long it has been run on flat and the sidewall could be compromised.

 

If this is a self sealing tyre then why not just remove the screw and in theory should re-seal itself?!

Yes it’s a self sealing tyre

when you take a self seal tyre to most tyre shops, most will refuse to repair  😭

one of the problems is that it takes  too long to scrap away the self seal layer which they need to do so the patch will stick and it ruins there buffer in the process.

i would leave the nail in the tyre for now but not indefinetly as it could deflate anytime even although its supposedly self seal.

when i had a nail in one of my pirelli p zero tyres, i took the wheel off the car and removed the nail, the tyre  started to go down, all be it slower than a standard tyre but still needing repaired.

 tyre places refused to repair for above reason, so i asked them to just remove the tyre from the rim, i then repaired the tyre with a patch that night [ it took me over an hour to scrap the  self seal layer away and fit patch so i can understand why they wont do it ]

next day i got the tyre fitted back onto the rim and to the tyre places credit, they did'nt charge me  but to be honest it's a lot of messing about.

imo, better not to buy this type of tyre, however if the car comes with self seal tyres then you dont have a choice.

does'nt always self seal though, and even if it did, would you trust it
