I see most online sources say no. But why not? It doesn't destroy the tire.
I'm sure manufacturers want to sell a new set of tires, and it is a " potential liability issue".
Also, if one tire needs to be replaced, does the other one on the same axle need replacement? probably so, as it might affect the AWD or such.

My understanding is they can be repaired like any other tire. The issue is that driving while flat destroys the tire, and since the shop can't know if you pulled over as soon as you got the flat or drove 50 miles to the shop, they won't take on the liability of repairing a bad tire.

Can runflats be plugged?

Well it depends who you ask doesn't it!

i have heard they wont do it to liability issues with what augerpro said about knowing how far you drove.

If you had a puncture thru the flat-tread - and didn't have "full flat" then most "reasonable" shops will repair.

If you had a puncture thru the flat tread - and "drove flat" - then most "reasonable shops" would inspect the sidewall-to-flat-tread for damage - and then decide if repair would leave you will usable tire - or if due to "flat-miles" the tire will be "dead".

If punctures thru side-wall or near sidewall/edges of the tire - the most "reasonable shops" will not repair.

Your issue replacing one tire with miles on all 4 - with a new tire - based on tread wear of the other tires - whether Extended Mobility or "normal tires" - yes can be conundrums.

On the positive side - sidewall punctures on "normal tires" especially low profile are increasingly common - and for those tires sidewall punctures are not repairable.

It's the way of the world mate !

I've been driving on run flat tires since 1999. In that time have experienced two punctures. After driving on zero pressure to the repair shop, in both instances, the tires were successfully repaired.

The first repair was plugged and then a vulcanized patch placed inside. Wasn't present when the second tire was repaired. Was told the same process was used.

Both tires preformed flawlessly until worn out.

That said, these early tires were noisy, hard riding and expensive to replace. Very much unlike todays tires.

A tire with a simple puncture assuming it hasn't been driven in an abusive manner over many miles can most certainly be repaired.

I was told that the manufacturers are the problem. They sell tires not patches. Heard that you can't patch the sidewalks which would most likely be a slash and not a hole. But, the tread can be with no problem as long as it will takes a patch. You just have to find an independent repair shop!

Thanks for the accurate post...

Hence, per the Tirerack list, Pirelli which is the typical tires for the GLC300, does not endorse repairing... 2/32" of wear?? that's 1.5mm. How can one even measure that?? They're splitting hairs!!
So I suspect most tire stores will not touch a damaged runflat Pirelli.
For us in So. Calif. there is a lot of rubbish and debris on the streets, from construction, and urban density. We also have the worst streets in America, with huge potholes. So the possibility of a tire damage or puncture is very high.

As the Extended Mobility tires are certainly a "upgraded" over earlier generation "run flats" - and give acceptable driving character - I am not a fan of the "slimmer" center tread - and frankly into turns the sidewall construction of the EM's tend to give a "pull" a bit.

I have several customers convert over to 700+ UTQG "standard" tires - one fav Yoko Geolanders - sure - you risk flats - carry TireFlat - and you have Roadside Assist anyhow -

I take this info as a whole from an engineering viewpoint that runflat connstruction is not significantly different from one manuf to another. The difference in stances on repair have more to do with how for out on the liability limb they want to go. For me, I carry one of these in my Porsches and a kit including a pump in the MB. If I had to use one, I will get to an independent tire store very soon and have it removed and the hole patched internally.

based on what i could find, it looks like the only 2 rft (or moextended) options are the scorpion verde and the contintental crosscontact lx sport ssr - has anyone found others?
