The car wheel evolution has followed the ease of needing to take the wheel off for a flat .
This has meant the total car weight has been boxed inside the four wheels .
If there was an arm on the otherside of each wheel
making a complete axel through the wheel then
the total weight of the car
could be divided by four and placed completely over each oval where road grips tyre .
Does this make sense or am I missing a fundamental ?

jockey as in caravan jockey wheel .
The idea is to crane the weight of the car over the wheels more by use of castor like construction . |

When the shelf has books in the centre and supports at the ends the vectoring of the weight to the supports is at angle to the shelf . If the books are divided in two and placed over each support the vectoring of weight is perpendicular to the shelf giving maximum balance . |

[bigsleep], try this: pick up an auto wheel by sticking something through the center and lifting with one hand on each side. Now try the same thing, but both hands on the same side. |

When the wheel is only supported from one side, there is a substantial torque moment exerted on the axle shaft from the car's weight. Put an outboard bearing on the axle, and the torque problem goes away. (You get a new set of problems, but...) |

[lurch] what are the main problems ? .
My idea was - instead of one large engine have 4 smaller engines on the outboard side of each wheel and passenger/load weight in centre . (real 4X4) |

[bigsleep], // wheel bearings aren't a problem // agreed. I'm only going down this path because that's what [wjt] is trying to change. |

[wjt] - //main problems?// Just for starters, try wheel alignment. Under the weight of a vehicle, your tires will flex. With the current method of attachment, with all the weight on one side, you know in advance which direction the flex is going to go. If your load is perfectly centered over the tire, there is no way to guess which direction the tire is going to flex. If both front tires just happen to flex the same direction, the car is going to swerve the other direction in response. So, to correct the swerve, you have to turn the wheels. But the instant the wheel direction crosses the direction of travel, the tires are going to suddenly reverse flex and your car darts the opposite direction. |

To transfer more power into motion the point of contact is where the tyre grips the road getting more weight "onto and closer to" that contact is better . The wheels don't necessarily need to be brought in , just component weight place outside .
Weight wider and lower .
A hubless wheel where the drive mechanism point is exactly over the treadprint could have the cars weight brought to the wheel from the outside , from front or back . |
