Why don't cars have more wheels

like in the military you know?

Why don't they have less wheels but more surface area?

so it doesn't get stuck

things in the military are armoured which makes them heavier, putting more strain on two exels

so they gave it 3 axels

answer is always costs.
two small axles cost more than 1 normal axle.
for civilian cars very relevant.
however:
4 axles, 2 up front and 2 in the rear, would be awesome. although bumps and holes in the road will appear twice as often, they shock the car with only half the power. which is nice.
more wheels would also lead to smaller wheels so you have more space in the car/under the hood. which would be ideal for mounting bigger engines.
anyway, here's a small design i did for a potential electric wagon. small front wheels for better earodynamics, frunk can or cannot be filled with batteries. double rear wheels (normal size) to carry the main battery pack mounted in the rear. Or, when front/mid battery pack is chosen the rear tires could be much smaller, decreasing friction and increasing trunk space.

Then why do most heavy construction vehicles have 2 wheels?

They have multiple sets to reduce the pressure on the ground similar to how caterpillar tracks work. Additionally, it improves off road capabilities.

Remember the six wheel f1? I'm sure there were advantages but it's always the naysayers slowing down progression.

>progression

please stop

Otokars competitor also has a 6x6 called the Pars.

Hi guys

more tires
how would you turn

Front tires are obviously steered. Like .
double rear axle either needs at least one steered axle or it'll see increased wear. (like with trucks, who have double unsteered rear axles).
Also: what are you saying? That the design is not perfect? that adding more axles complicates things like says?
That it is not economically viable like says?
I think you don't really contribute anything other than noise to the thread. which is a shame because it's an interesting thread. Albeit it all being hypothetical.

nobody is going to buy a car that needs 6 or 8 tires
now with the new stock low profile tires people are paying 600-900 a set of tires and they sure aren't gonna buy a car that is gonna need 1200 a set (and also looks goofy)

Why did they even let the mammoth car in the race

>Why don't cars have more wheels
giving all your money to big rubber co.

Construction vehicles aren't hauling ass through enemy-occupied territory.

Different applications different designs. The primary reason APCs use more than 4 wheels is To limit the effectiveness of mines. They also help distribute weight better and allow for a smoother ride, which is a big deal for target engagement on the move, as well as crew comfort. Soldiers wont be as effective if they throw their back out on a pothole.
Cars dont really have these concerns, and cost and complexity often decide the majority of engineering descisions. 6 wheeled cars exist all over the place in america, we have "dualies" theyre trucks with longer axles with a tire put parrallel To the normal tire. You also have the 6x6 G wagon

no rules, ho

Cost, wheels/bearings/suspension compenents are expensive.
Rolling resistance, more wheels=more resistance.
Not necessary, four wheels can support a car just fine.

I suppose that's also why they let the Mach 5 race with all the bullshit he's got in it

nice legomobile

lmao

There's no point in adding more axles really, you want more surface area in contact with the road? Get wider wheels.

Military APCs and construction vehicles have 6, 8, or 10 wheels because they are heavy. If they only had 4 wheels, the ground pressure would be too high and they would get stuck on soft ground really easily and the tires would be at risk of failing due to excessive loads. Cars don't need to worry about this because they're fairly light and rarely designed to go through rough terrain. Thus, for a car, more than 4 wheels is just excessive complexity, meaning more parts that can break and more weight. There really isn't a compelling argument for having more than 4 wheels on a consumer car.
