Chaps.

Noticed today I have a small screw in one of my front tyres. How urksome.

It is nearly new so I am loathed to buy another.
Does anyone here have any experience of professional puncture repair?
I appreciate it will never be as good as a new tyre but am willing to give it a go on a positive recommendation.
The screw itself is quite small, has a head of about 4mm and is in there good and tight. I have no pressure loss at all and the thing wont budge. Dont want to give myself an instant flat but undoing it though.

My train of thought is that whilst these repairs may be okay for a 'normal' car, what are the effects likely to be on my M5 which is used to doing teensey weensey higher speeds than your average reps hack.

The last thing I want is to have a blow out on my weekly commute on the 'Autobahns' LOL.

Your thoughts appreciated,

Neil

How far from the edge of the tread is it? Assuming it's not near the sidewall it should be repairable by a decent tyre shop by plugging from within. One school of thought says that the speed rating is downgraded by one notch after the repair.

It is repairable by the sound of it. You just need to find a repairer happy to do it.

The British Standard for tyre repairs states that tyres must retain their original service description after repair, there is no margin for reducing the speed capability. Tyres of any speed rating are alowed repairs in the tread area, which is defined as a %age of the section, up to 6mm diameter. At that size there is no significant structural damage.

Exactly where is the screw? If it is in one of the tread blocks, the odds are it hasn't yet penetrated and could be safely removed, but I would suggest that you are at a repairer's depot before you try that for obvious reasons!

The actual head of the screw has now been scrubbed away with wear. Its only a little chap which I doubt is that long.
It is right in the centre of the tyre between two tread bars.
I may twist it out with some needle nose pliers but hurrily twist back if I hear any hissing!

Unfortunately, between the tread block is the thinnest part, but it's worth a try. Often it takes screws etc quite a while to work through the various plies in that area.

Let us know what happens!
