Car tyre puncture kit

I do indeed!

Which shape have you bought? An E63? It would not have come with anything, since this was the time that BMW had Run-Flats from the factory.

Later cars from all brands now have Continental kits, like the link below, which do work well. My E46 M3 came with a fancier looking version of this, as M3s didn't have spare wheels either.

I doubt these work in the sidewall, but they do work as a quick fix for normal punctures to get you out of trouble.

Now, for the tyre repair kits, I've used them on a motorbike and on a car. They do work, and work well. I think however, they may be illegal or in a grey area. I know Tesla recovery folks use these. I do also keep one of these kits in my boot, as per the link below.

On both, I've put proper puncture repairs in from garages at the earliest opportunity, mainly as I've never had a proper puncture repair fail. Several folks have seen these last a long time however, so the choice is yours there really (y)

Kit is ordered 👌

Personally I use strings.
Never had a problem and never had them replaced.
I understand in high pressure tyres in heavy vehicles they can pop out.
If you fit them without faffing about you hardly lose any air.
And you can fit mutliples in large holes as a get out of trouble patch.
We have a BMW with no spare in the family and it is not on runflats anymore.
In the boot is a compressor and a can of patching goo you put in via the valve.

We charge a wheel/ Tyre cleaning fee, its awful stuff to deal with and get rid of. Its very very hard to get repair patches to stick to a tyre that's had any sealant in it.

However, OKO is amazing stuff and seemingly works miracles on some sizeable holes.

I wouldn't suggest buying the quantities we sell but worth a read/ watch.
