No. Bigger wheels roll slower than smaller wheels. They roll slower because they have a larger circumference and they take longer to roll. Smaller wheels have a smaller circumference meaning they go faster.
NO. The smaller the wheel the more revolutions it turns if both are driven at the same speed. So, the smaller the wheel the faster it turns.
Bigger wheels are easier to run on uneven ground upto some extent
No they dont.
The larger the wheels have a higher center of mass than a smaller one. The higher the center of mass, the smaller the tilt needed to cause the wheel's center of mass to move outside its base and cause the wheel to roll over.
The larger wheels roll much easier over rough terrain. Smaller wheels can get swallowed by small divots and bumps where a larger diameter wheel will roll over the smaller divot's without dropping down in.
A smaller wheel will have less rotational inertia - it will be easier to get it spinning. A smaller wheel will also make the overall length of the bike shorter - an advantage during storage. A smaller wheel will also be proportionally stronger sideways - which is an advantage during hard riding. The downside of all this though is that a small bump in the road will be a proportionally bigger obstacle than for a bigger wheel, which makes the ride harsher. If you're a really fast rider the smaller wheel will offer a lower top gear ratio than a bigger wheel, which will either limit your top speed or force you to get custom chainwheels to compensate.
Bigger wheels make it easier to roll over cracks in the road. softer wheels are good for riding vert because they grip the ground alot better than hard wheels.
The bigger the wheel, the easier/smoother it will roll over small obstacles. But the bigger it gets the weaker and heavier it gets. And eventually it gets so big that it will begin to affect the way it can be fitted into a reasonably normal-looking bike frame. The smaller the wheels become the stronger they get, but they will also ride bumpier. 26" is right there in the "harmonic" range of sizes for a bicycle wheel where it's big enough to roll smoothly, yet small enough to be strong & fit nicely into a frame.
No. It effects the vehicles speed, and how the horsepower is used. It take more energy to move larger wheels, so the vehicle will feel less powerful and because the larger wheels take longer to roll, the vehicle will be slower.
They roll, but they are really rather poor wheels. I would use something else.
Per given number of rotations/time, the larger the distance covered per rotation/time the higher the speed. If you pit them against each other on a ramp in a vacuum, then they'd roll at the same speed, different rotations/time 's In reality you have to factor in wind-resistance is greater than that on the smaller wheel.
