Tyre repair, bung type, or patch?

[Mr Whippy]

Found a screw that had screwed itself into my rear tyre. Wasn't leaking or anything but it needs sorting.
I spoke to BMW as it's in for service today anyway, and they said they would use a bung, but my brother said a rigid patch is better (when he worked at a tyre place 10 years ago or so they didn't like bungs much, but that was 10 years ago)


So, what is the best thing to do? Bung style or patch?


It's right in the middle of the tyre, just to the side of the fat centre tread block that runs around the circumferance.


Just curious if these bungs are a cheap low-labour alternative, or are now technologically better?!

Thanks

Any repair I've had in the last 5 years has been a bung, and I've never had a single problem.

Same here. I don't think I've seen a patch used on a tyre in years.

I had a bung put in one of the Elise's tyres and had no problems with it too. Didn't even cost me anything - the tyre place did it for free.

[Mr Whippy]

Sounds like I have nothing to worry about then!

I'm a big fan of tyres being right and dependable, so if it'll be as good a repair as can be made then I'm happy


Thanks all!

Well BMW patched it, yay.

Now I have this one in the other rear tyre



Is it ok to patch/bung, borderline, or too close to the edge?



255/35R18, so it looks close to edge but its probably 3.5cm in from the tyre wall edge... hmmmm...


I'm sure they are off this gravel drive at work, a friend and I found about 15 nails the other week after a walk up and down for 10 mins... (about 150m of gravel each way to the garages from the road)

Should be OK. It's only the sidewall they can't patch/plug.

[Mr Whippy]

"Too close to the sidewall", said one tyre place. I told them to leave it... clearly falling back to the sell a tyre approach rather than having a look see

Think I'll DIY this one with a patch at the weekend... I'll just see how it looks inside and then decide... (wife had a nail near the sidewall but upon removal for replacement it wasn't actually through on the inside)

Hmmm, using http://www.etyres.co.uk/glossary-tyre-terms?term=t...

"Above 200mm width, 70% of width"


And this...

70% width plotted over:



It looks like it's on the line. Since 200 > 255 is a fair old jump, and the trend is that the wider the tyre the larger the %, then I'm fairly happy that, assuming no iffy stuff when I remove the tyre, it can be repaired ok... especially since it'll be a tyre in need of replacement again in 8 months anyway.


Hmmm

I think you'll be lucky to get that repaired mate
