How to identify run flat tires?

[bags]

My brother asked me how he would know if cars he was looking at buying had run flat tires on them. I told him it should be identified on the side wall. Well, after a quick google search, it seems only European tires have this (thanks tire rack).

So I am asking the question, is there a "standard" marking on the sidewall for run flat tires?

stab with a knife then see if it pumps back up...??

Just kidding man I have no idea but that's a great question though...

The letters RSC should be on the sidewall.

Depending on the brand it should say, RFT, RSC, SSR, DSST or ZP

I believe the RSC (inside a circle) designation is Universal (similar to the snowflake symbol fro snow tires for example). You will find it on all runflat tires of every brand. The RFT, SSR, DSST, ZP, etc designation is manufacturer specific and will usually be part of the tire name (e.g. Potenza RFT or Pilot Sport 2 ZP, etc).

True statement

samger is correct. Every tire mfg. uses a different name for the run flat tire.

Hey if the vehicle in question does not come with a spare tire.....then it must have runflats. I think the gov.t requires this. Check it out...if it came from factory w/out a spare.... gauranteed runflat tech

No there are no laws regulating this. The M cars come with regular non runflat tires and without a spare.

I would not think that would be doable... runflats will not HELP if you shred a tire! Or if the hole is too big.
