You simply need reinforcement in a tire which must withstand a couple of tons, and steel happens to be suitable and cheap. Incidentally, it also protects against punctures somewhat. | |

Jun 29, 2020 at 12:05 | comment | added | Mark Segal | @Criggie that's not necessarily true, as the ratio between the mass of the vehicle and the tire size might not be so different between a bicycle and a car. or not. | |
Jun 29, 2020 at 12:04 | comment | added | Criggie♦ | @MarkSegal right, but that's not the point. A car has more power total, to overcome the drag of bigger thicker tyres. An identical car would roll better on more efficient tyres, at the risk of higher puncture risk. | |

Jun 29, 2020 at 11:47 | comment | added | Mark Segal | a 1.5 ton car doesn't use all the 100 horsepower when coasting. it may use 10-30 horsepower to maintain a 100 km/h speed. @Criggie | |
Jun 28, 2020 at 21:02 | comment | added | Criggie♦ | To expand this, a 1.5 ton car with 100 horsepower is ~75,000 watts or 50 watts per kilo. A 100 kg cycle+rider doing 250 watts is 2.5 watts per kilo, so approximately 1/20th that of the car. The motor vehicle has much more power to burn (ie waste) on overcoming rolling resistance from hefty tyres. | |
