Is the pneumatic tyre days numbered?
Discussion
I've never seen the point in the stupidly wide & low profile tyres & alloys on everyday vehicles these days. Yesterday I bought four steels so I can change mine from 215/45/17 to 195/65/15. I'm simply fed up with the 215s, also they're like sitting on a skateboard going through a quarry.
Dear sh,
However one has to ask how often you do drive through a quarry?
It's all about the style/ride/handling compromise. For some people unless females need a sports bra to nip to Tesco it isn't hard enough.
Others, myself included, prefer something smoother - I have changed springs (on my Monaro) to something more stock but kept stiffer shocks and poly bushes.
There's a lot the designer can do isn't there to mitigate against the low-profile shakes?
Having said that IIRC there was some futuristic car on these very pages with very tall, narrow wheels and very high profile tyres. The contact patch stays the same (as a low profile tyre) as the rolling radius is higher,
regards,
Jet

No.
What would you replace them with?
Tweels are the closest we've come to designing a good replacement, but there were some serious NVH issues with them.
Air, however old fashioned, has some wonderful properties.

And overly complicated expensive solution that performs worse then the orginal in all areas but it costs 4 times the amount. but it does have a nice shiny button

215 is hardly wide though. I had a 200 section on my last bike.hopefully one day they will be replaced by nanobots
they'd be able to actively mould themselves perfectly to the road, alter between different grip and comfort profiles at the touch of a button, something the size of a bike tyre would give more grip than a current formula 1 tyre, and could last for years.
I'm sure 60 years ago no one would believe that by now we would have all have TVs that were made with 4 million transistors or LEDs in a grid to control individual pixels

I'm pretty sure that 60 years ago tyres were rubber and filled with air, and water was wiped off windscreens with little mechanical arms.they'd be able to actively mould themselves perfectly to the road, alter between different grip and comfort profiles at the touch of a button, something the size of a bike tyre would give more grip than a current formula 1 tyre, and could last for years.

60 years ago they thought we'd all be using hover cars by now.
Predicting the future is quite tricky. Plus I'll be dead in 60 years so it doesn't matter.

time for a shake up if you ask me60 years ago they thought we'd all be using hover cars by now.

sonic windscreens and nanobot tyres
you are right about predicting the future though, in 60 years time personal transport may have all but ceased to exist
