sidewall

A run-flat still needs to be serviced if punctured and is still vulnerable to sidewall damage and potential blow-outs.

They are also not to be driven on AT ALL in the event of a sidewall puncture.

It mostly has to do with cap improvements that help prevent the sidewall from opening up at the shoulder.

It's on par with noticing a crack in your sidewall or a badly frayed brake line.

Or you could switch (maybe another Tesla owner would trade) down to a rim size with a more reasonable sidewall profile.

The aspect ratio (sidewall height) of tires has decreased in a lot of vehicles though.

Plus because the sidewall is so thick they're a huge pain in the ass to get on the rim so chances of rim damage is much higher when you put these on.

But, that doesn't make for good linkbait headlines nor revenue-generating eyeballs on sidewall ads.

I have always wondered if it is the lack of sidewall on a 225/45R17.

They are big sidewall donuts, but no pizza cutters.

A little off-topic, but an increasingly smaller number of cars are coming with spares (as someone who has experienced sidewall tire damage on the highway, it's an alarming trend).

You really need a way to search by make/model/year for something like this or at least a quick guide on how to read the sidewall to get the information.

Sidewall height is even stranger - it's represented as a percentage of the section width.
