Solid tyres?

[mjr]

The ultimate folly. If you're touring by bicycle, can you really not spare a few minutes to fix a rare flat? If not, shouldn't you be using the lowest rolling resistance tubeless to speed things up, rather than something that feels like M+ or worse, depending who you listen to?

Tyres are designed for a maximum contact patch deflection and many turbo trainers are under the limit - about 80mm (dia for the roller) and heat up tyres very quickly and hot enough to make them delaminate.

A spoked wheel receives a double compressive load with ordinary and tubular tyres. The spokes put a compressive load of around 3 tons (30 000N) on the rim and the tyre about 300N. The tyre's compressive force comes from the scissor-jack action from the cords in the tyre which constrict the tyre's circumference under inflation. It is this circumferential load that allows us to take a tyre on and off without too much trouble, because it needn't be as tight thanks to the compressive force that is applied after fitment. This force also allows for slight variations in tyre diameter which are normal for manufacturing processes.

Wow. I knew there'd be a large difference, but I hadn't realised it was 100:1

Do they not come in 2", 40psi versions, or should I just duct tape a bunch of old sponges to the rim?
