The aviation industry has studied this problem very carefully, and has come up with a general guideline as to when hydroplaning is a risk.
The formula used in the aviation industry is:.
Knobby treads actually give worse traction on hard surfaces! This is because the knobs can bend under side loads, while a smooth tread cannot. The bending of knobs can cause discontinuities in handling: Many tire makers market "combination-tread" tires, that are purported to work well easy riding bikes both pavement and dirt.
Generally, they don't. The usual design is to have a smooth ridge down the center of the tread, with knobs on the sides. The theory is that the ridge will sold a smooth ride on pavement, solid rubber road bike tires the tire inflated fairly hard, and the knobs will solid rubber road bike tires into play off-road, with the tire running at lower pressure or sinking into a soft surface.
Another aspect gike this design is that the knobs are intended to solid rubber road bike tires into play as you lean into a turn. In practice, combination-tread tires best bicycles for women work all that well.
They do OK in dirt, but they're pretty lousy on pavement. They're much heavier than street tires, and if you corner aggressively, the transition from the center strip to the knobs can cause sudden washout.
They aren't quite solid rubber road bike tires slow and orange cycling vest as true dirt tires, but they're much worse in this respect than smoothies.
If you mostly ride on pavement, but also do a fair amount of dirt, a combination solid rubber road bike tires on the front may be a good choice for you, with a road tire solid rubber road bike tires the back.
There is a relatively new, international system of tire sizing which eliminates these confusions. This is explained in considerable detail on this site in the article on Tire Sizing. The trade-off with this is that the thinner the tire gets, the more fragile it is, and the sooner it will wear out. The trade-off with this is that if you pump the tire up too hard, you lose the benefits of pneumatic tires: In addition, extremely high pressures require a stronger heavier fabric and stronger heavier rim flanges.
When riding on a smooth surface, rolling resistance does decrease theoretically with any increase in pressure, but with modern, high-quality tires the rolling resistance at correct inflation pressure is already so low that the infinitesimal reductions gained are more than outweighed by the trade-offs.
In practice, bicycle sales online surfaces aren't perfectly smooth, and overinflation actually increases rolling resistance, due to vibration.
Tire width and pressure are inextricably linked. It is a serious mistake to consider one independently of the other.
Generally, wider solid rubber road bike tires call for lower pressures, narrower tires call for higher pressures. Consider, for example, a tire one inch across, at a pressure of PSI pounds per square inch.
Air is pushing down against the bottom half of the tyre cross-section with a force of pounds per inch of length. Each sidewall of the tire solid rubber road bike tires half that load, and so each inch of length of mountain bike tube sidewall will be under a tension of 50 pounds.
Now let's consider a tire twice as wide, two inches across, at the same PSI. Each inch of sidewall will be under a tension of pounds. So, a wider a tire would ride harder, and need stronger fabric, if inflated to the same pressure. The part of the tire that is actually touching the ground at any moment boke called the "contact patch.
For instance, if the rear tire clear mountain bike glasses a bike solid rubber road bike tires supporting a load of pounds, and the tire is inflated to PSI pounds per square inch the contact solid rubber road bike tires of the tire will be roughly one square inch. If the pressure is reduced to 50 PSI, the tire will squish out until the contact patch has become 2 square inches or until the rim bottoms out against the tire.
A common debate among cyclists centers on the issue of whether a wider tire has more or less rolling resistance at the same pressure. The constant pressure is proposed because it appears more scientific to eliminate this as a variable, but this is not realistic in practice. The short answer to this question is that, yes, a wider tire of similar construction will have lower rolling resistance than a narrower one at the same pressure.
This fact is, however, of no practical value. If you are comparing two tires of similar construction, with the same load, and the same pressure, either the wider tire is overinflated, or the narrower tire is underinflated! A tire is supposed to deflect a bit under load.
This deflection the whole purpose of pneumatic tires. When you sit on your bike, your tires should visibly bulge out at least a bit under your weight.
If they don't, they're overinflated. Most tires have a "maximum" pressure, or a recommended pressure range marked on the side of the tire. These pressure ratings are established by the tire manufacturers after consultation with the legal and marketing departments.
The lawyers want the number bike shop bay city mi conservatively low, in solid rubber road bike tires the tire gets mounted on a defective or otherwise loose-fitting rim. They commonly shoot for half of the real blow-off pressure. The marketing department wants the number high, because many tire purchasers make the unreliable assumption that the higher the pressure rating, the better the quality of the tire.
Newbies often take these arbitrary ratings as if they had some scientific basis. While you'll solid rubber road bike tires get in trouble with this rote approach, you will usually not be getting the best possible performance.
Savvy cyclists experiment with different pressures, and often even vary the pressure for different surface conditions. Optimal pressure for any given tire will depend on the load it is being asked to support.
Thus, a heavier rider needs a higher pressure than a lighter rider, for identical tires. Used bikes nyc shop surfaces generally call for a reduction in pressure to improve ride comfort and traction, but there is roas risk of pinch flats if you go too far. Even at the lower appropriate pressure, wider tires, because they also solid rubber road bike tires deeper, are more immune to pinch flats.
Rider skill also enters into this: The table below is based on my experience and a certain amount of guesswork, and should only be used as a very rough guide to a starting point.
Tire widths are in millimeters, pressure ribber in pounds per square inch. Note that these recommendations are 700c rims on the actual tire width.
Many tires are marked wider than they actually are. Crosscountry mtb Quarterly Magazine has published an article recommending optimum pressures. Please do not contact us with questions about specific tire pressure recommendations!
Trikes and two-wheel trailers are very different from bikes, because they don't lean in solid rubber road bike tires. Most tire wear comes from cornering forces.
On a bike, these forces act on different parts of the tread, according to how far one leans into various corners at various speeds. With a trailer or trike, all of the wear is concentrated on the middle of tores tread. If you overinflate trance mountain bike tires, you'll be riding on only the very center of the tread, and it will wear rapidly.
In addition, wheel alignment is never going to be perfect. As a result, the paired tires will always rbuber a bit. If the tires are rock-hard, solid rubber road bike tires will cause rapid wear.
If the tires are softer, they can flex slightly sideways to accommodate the scrub, without wearing the tread tres. With trailers, severe overinflation can also lead to flipping the trailer over, due to the tires' bouncing on road irregularities. The load on trailer wheels is often very bicycle shops close to me. Adjust pressure accordingly, and evaluate pressure by tire drop.
