I don't know whether anyone agrees with me but I can't help wondering why in this age of cars without a spare wheel, tyres are not solid ( filled with bubbles as in Aero Chocolate) I have a disabled scooter with solid tyres & with good shock absorbers I can imagine car tyres would be much safer if they were not subject to blow outs, Before anyone can say it would be detrimental to tyre manufacturers sales we would still be governed by tyre tread rules & have to replace tyres when they become worn.
Tyres need to be inflated to match the requirements of individual vehicles and so if only solid tyres were available we would need thousands of variations.If they were not correctly matched then wear and tear would be very high.
You can get solid tyres for bicycles. I'm told that you feel every bump. I guess your scooter is much the same even with outstanding suspension. I wonder if at road speeds it is difficult for suspension to compensate, or at least at a reasonable cost.
How often do you get a 'blowout' I have never had one in 45 years of driving in the UK,Africa and the Middle East. I have had punctures but never one so bad I could not get to a tyre depot . I do not think the benefits would outweigh the problems. Bright sparks idea is correct, some cars need a lot harder (higher pressure) tyre than others. My car has a 15 psi difference between the front and back tyres so I would need 2 spare 'solid tyres'.
We would still have the same tread wear issues or more so if the tyres are not matched......but just consider the disposal costs...not to mention the purchase costs.This is 2016 not 1916.
I've had a couple of blow-outs on Britain's motorways. Very difficult keeping the car going straight and onto the hard shoulder safely. Both on apparently decent tyres.
pretty sure the experts will have considered this in great detail already, and presumably decided against it.
they spend millions on developing better and better vehicles, so if this would work the best they would be doing it already.
