Is it harder to ride a bike with flat tires?
As you move forward and the tire rotates, the part of the tire that is starting to touch the ground has to be deformed (since the tire is flat). … That loss has to be even by the cyclist, which is why it is more difficult to ride a bike with flat tires.

How much do tires affect bike speed?
The average speed would be predicted to be reduced by about 0.5 km/h due to having under-inflated tires, or 4 hours more of total cycling time. If riding under-inflated tires also leads to extra punctures due to pinch flats then even more time may be lost.
Is it bad for a tire to sit flat?
Do not leave a car with a flat tire sitting for any length of time. It is about the worst thing you can do to a tire (tyre). The side walls will get weather checked (develop very small cracks that you can barely see). You will never be able to trust that tire again.

Do Small Wheels on a Bicycle affect speed? This isn’t such a simple question to answer because it all depends. A small wheel is able to spin at a higher RPM (revolutions per minute) because of the smaller circumference, meaning it would take more effort to get to the same speed on a bike with larger wheels.
Is wider tires better?
From a safety point of view, both types have their good sides: On a dry road, wider tires will offer more grip than narrow ones, but the risk of aquaplaning will be higher with wide tires. – In the winter, narrow tires are better under extreme conditions as they provide higher surface pressure against the road.
Do bikes with bigger wheels go faster?
Summarizing the two studies, the rumble strip tests showed that on smooth and rough roads, larger wheels don’t roll significantly faster. The Swiss study suggests that, for mountain bikes, larger wheels may be what makes 29ers faster than smaller-wheeled mountain bikes.
Why did my tire go flat overnight?
Avoid puncture blowouts by driving around debris in the road or in parking lots whenever possible.
