Benefits of Solid Tires for Bicycles: Improved Ride & ...

Average car tire weight 25lbs. Average truck tire weight 120lbs.

Look at the average sedan tire 205/60/15:
section width 205mm, section height (.6*205) 123mm

Tires are not perfectly cylindrical but you can estimate their volume:
15in = 381mm
(205mm)*pi*((381mm+123mm)^2 - 381mm^2) = .07m^3

A tire is primarily carbon black, synthetic rubber, and natural rubber.
natural rubber has a density of .94 g/cm^3 = 940 kg/m^3
synthetic rubber has a density ~1.2 g/cm^3 = kg/m^3
Carbon black is just a reinforcement, and becomes neglible when you are talking about filling the entire inner volume with rubber.

You solid rubber car tire (assuming your using the least dense material of natural rubber) now weighs 66kg or 145 lbs.

Now here's the logistic portion of it beakman, you have increased the weight of your tires 5-6 times. Thereby, you have reduced the amount of tires you can ship at any time because you will exceed the gross tonnage capacity of whatever you are transporting your tires with, such as overland freight, 5 times as fast. Your shipping cost would go through the roof, and tires would be rediculously expensive.

Also, you'd never be able to produce solid rubber tires with natural rubber, so your only choice is to use synthetic rubber which is derived from petroleum. Ignoring the peak oil and enviromental footprint aspect of this, your cost would again increase from oil competition so you could produce rubber. That is why the solid tire concept is logistically impossible.

Things are engineered in a way for a reason, instead of insulting someone who is trying to enlighten you, perhaps you should take a minute to think and research before you question their veracity
