Screw In Tyre

[Davetheref]

I've just found a bloody great screw stuck in the middle of one of my front tyres. Of cousrse it has to be when most of the tyre places are closed (well, the one I want to use anyway). Kwi Fit are open and want to charge

I was always told that it was far more difficult to repair a screw hole rather than a nail one as the screw rips the tyre as it is driven in. However this might be a con job to get a new tyre out of me.

It's your call as to whether you drive, I can't see it doing any more damage as long as it's fully seated already, but I wouldn't go doing any track days until it's sorted.

i wouldn't drive further than a few miles until you get it fixed - just to be on the safe side.

 

if you are going to be replacing that tyre in the next year i would put the

i was also told a screw puncture is not fixable. only nails, and that depends on where in the tyre it is, ie - side walls are a no go area.

 

if you can put the spare wheel on - but otherwise dont drive too fast, if not at all.

 

if tred is low, (like it was on one of ours once) we just replaced the tyre.

its not really a tech question , its your familys safety , you decide , personally i'd go with the spare for today , and new tyre, you dont want to do 70mph with your kids in the car and rely on a rubber bung

They are not allowed to "bung" it as you say, they have to Vulcanise them.

hi steve , sorry dont know what vulcanise means :) :)

hi steve , sorry dont know what vulcanise means :) :)

vulcanization (vŭl'kənəzā`shən), treatment of rubber to give it certain qualities, e.g., strength, elasticity, and resistance to solvents, and to render it impervious to moderate heat and cold. Chemically, the process involves the formation of cross-linkages between the polymer chains of the rubber's molecules. Vulcanization is accomplished usually by a process invented by Charles Goodyear in 1839, involving combination with sulfur and heating. A method of cold vulcanization (treating rubber with a bath or vapors of a sulfur compound) was developed by Alexander Parkes in 1846. Rubber for almost all ordinary purposes is vulcanized; exceptions are rubber cement, crepe-rubber soles, and adhesive tape. Hard rubber is vulcanized rubber in which 30% to 50% of sulfur has been mixed before heating; soft rubber contains usually less than 5% of sulfur. After the sulfur and rubber (and usually an organic accelerator, e.g., an aniline compound, to shorten the time or lower the heat necessary for vulcanization) are mixed, the compound is usually placed in molds and subjected to heat and pressure. The heat may be applied directly by steam, by steam-heated molds, by hot air, or by hot water. Vulcanization can also be accomplished with certain peroxides, gamma radiation, and several other organic compounds. The finished product is not sticky like raw rubber, does not harden with cold or soften much except with great heat, is elastic, springing back into shape when deformed instead of remaining deformed as unvulcanized rubber does, is highly resistant to abrasion and to gasoline and most chemicals, and is a good insulator against electricity and heat. Many synthetic rubbers undergo processes of vulcanization, some of which are similar to that applied to natural rubber. The invention of vulcanization made possible the wide use of rubber and aided the development of such industries as the automobile industry.

Dave, get the spare ready and then pull the 'screw' out...I had one which I left in til I got to the tyre place, they jacked it up, took the wheel off then pulled 1/2 a csrew out that had just wedged into the tread! Put the wheel back on and off I went relieved!!

 

fingers crossed......

I've just found a bloody great screw stuck in the middle of one of my front tyres.

Will it be ok to drive around for another day as I'm not losing any air whilst its in or would I do a lot of damage to the tyre. They are 17" low profile. :)

 

Just ask yourself how long have you been drivin with it in and not noticed.

 

Wait until tomorrow and don't pay the robbin *********.

 

Agree with putting the

[Dave-G]

Screw threads have held it in thus far - leave it be if it aint losing air and enjoy the weekend mate.

A puncture repair can only be attempted on the central section of the tread. Sidewalls and the shoulder of the tyre are not repairable, as a rough guide the shoulder is approximately the first inch in from the sidewall to the tread (where the smooth sidewall finishes and the tread pattern starts)

 

A "rubber bung" is still used in conjunction with a vulcanising chemical (think adhesive)

 

Screw damage can be fixed BUT a screw is far more likely to disturb or damage the fabric or steel plies, often forcing strands into the the tyres cavity. If this is the case a repair is a no-no. Smooth sided items such as nails are far less likely to damage the ply of the tyre and are therefore more likely to be the cause of a repairable puncture.

[Davetheref]

Thanks for all the replys people. I have left it in till today as when I checked, its not losing any air.

As for the spare, I dont think I've ever looked at it , let alone use it (especially after all the spare wheel problem posts on here with the cable etc).

Marky, hoping you are right and it is just a very short screw but daren't pull it until at the tyre place. It could be short as its a large headed screw top, fingers crossed and also hope doesn't mean a new tyre at the end of this.

[Davetheref]

The screw did go through the tyre but it was fixable.

What was worrying is that I need to change both my front tyres as they are both down to the wear indicators. They have only done 12000 miles and are Dunlops. They were a resonable price when I bought them but will never use again. The tyre guy tells me thaey are nice and quiet but have softer rubber, hence them wearing faster.

The continentals that I had previously lasted 20000 miles and still had a bit left when I changed them. So it looks like I will go with the Continental Sport again. Cost a bit more but save in the long run.

[Guest MATT]

i was also told soft rubber offers more grip? but have not yet experimented with it.

 

MATT

[Davetheref]

I would agree with that Matt. They did seem to have better grip but knowing what I know now about the wearing I would not go with them again.

[Guest MATT]

Yeah, i have got dunlops on the front, that i wont be having next time.

 

at the moment im trying some Avons on the rear.

 

the Continentals do seem good - and the lorry drivers seem to have them on their lorrys.

[shepheap]

My Dunlop 2020s wore out very quickly on the front.

 

Have just fitted Fortuna F2000 XL to the front at

[Dave-G]

My philosophy is that the softer rubber ones wear quicker - but are cheaper. Then when we consider a puncture on a fairly new tyre it's better than potentially having to ditch an expensive one.
