How does a wide MTB tyre have lower rolling resistance than a slim gravel tyre?

Asked by: Jessica Moore

This is because, at the equal pressure, the casing tension of the wider tyre is higher and the contact patch is shorter and wider. The first of these factors means less energy is lost to casing flex, and the second reduces rolling resistance because the shorter, wider contact patch reduces frictional losses.Sep 3, 2021

How does tyre width affect rolling resistance?

Tires with a smaller diameter have a higher rolling resistance with the same inflation pressure, because tire deformation is proportionally greater. The tire is flattened more and is “less round”. Wider tires roll better than narrower tires.

Do narrower tires roll faster?

Myth 1: Wider Tires Are Slower



For almost a century, cyclists ‘knew’ that narrower tires roll faster. Some people realized that in theory, wider tires are faster due to their shorter contact patch, which deforms less as they roll.

Are wider mountain bike tires better?

Consider wider tires: Though heavier, wider tires offer better traction (a plus for sand) for a more confident feel. They also accept more air volume to absorb bumps. You can go with a wider tire on a current rim or get wider rims to accommodate even wider tires.

What factors affect rolling resistance tyres?

Tire pressure, tire diameter, tire width, tire construction, tire tread and other factors all have an effect on rolling resistance. On a completely smooth surface the following applies: The higher the inflation pressure, the inferior the tire deformation and thus rolling resistance.

Do wider tires have less rolling resistance?

In the end, then, our roller testing shows that wider tyres do produce less rolling resistance than narrower ones at equal pressures.

Are wider tyres better than narrow ones?

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 wider tires give better acceleration?

Slower Acceleration and Harder Steering



Wider tires are heavier, which, as a consequence, adds more weight to the car. This decreases the car’s acceleration. With its large contact area, wide tires not only slow down acceleration but also cause hard steering and poor car handling.

How do you reduce rolling resistance?

One way to reduce rolling resistance is to increase air pressure in your tires to the recommended amount. With increased tire pressure, the tire ends up getting less deformed while going down the road, resulting in less energy wasted.

What is the benefit of wider bike tires?

With a larger chamber of air between you and the road, a wider tyre allows you to drop the pressure without running the risk of a pinch flat (where the inner tube gets punctured as a result of being sandwiched between the wheel rim and the ground).

What is the best tyre width MTB?

This means a compromise has to be met: cross country mountain bikers tend to use tyres with a width of 1.8-2.2 inches, while more aggressive ‘All-Mountain’ riders and downhill racers use tyres up to 2.1 and 2.4 inches wide.

How wide is too wide MTB tires?

Quote from video: And if you're riding resembles like perry roubaix. Then 30 mil rubber like lizzie diegnan wrote to victory. Or even wider. That's probably going to be your best bet.

Are fat tires good for mountain biking?

The main difference between fat bikes and regular mountain bikes is that fat tires are wider than standard tires, making them more suitable for riding on soft surfaces like sand, mud, or snow and hard ice-covered areas. The unusual proportions of fat bikes draw attention.

Do wider tires slow you down MTB?

Width has the same negative effect on rolling resistance on any tire, it’s just that the front contributes less to the overall resistance.

Do wider bike tires slow you down?

Why are wide tyres getting popular? It turns out that despite previous thinking, wider tyres are no slower than skinny tyres, and in some cases actually produce lower rolling resistance.

Are wider bike tires more stable?

Quote from video: People also ask

Why are wider tires faster?

It turns out wider tyres are actually faster along with the benefits of increased comfort and traction. In the very early days of road cycling, tyres were wide because the roads were poorly surfaced, and in many cases, not even surfaced at all.

How do you lower rolling resistance?

One way to reduce rolling resistance is to increase air pressure in your tires to the recommended amount. With increased tire pressure, the tire ends up getting less deformed while going down the road, resulting in less energy wasted.

How do I stop my bike from rolling resistance?

If you want to cycle faster – or ride at a given speed for less effort – you need to choose your tyres carefully and set them up right to minimise rolling resistance.

Does tire rolling resistance increase with speed?

The force of rolling resistance does not change at higher speeds.
Feb 22, 2011

What are two factors that affect rolling resistance?

Factors that contribute to rolling resistance are the (amount of) deformation of the wheels, the deformation of the roadbed surface, and movement below the surface.

Does weight affect rolling resistance?

Extra weight causes a greater deformation of the sidewalls and tread of a tire, thus, increasing the rolling resistance. Rolling resistance increases in direct proportion to the weight that the wheel supports, and is equal to about 0.3 to 0.5 percent of the load on the wheel.
