I have a bicycle rim that is marked 26 x 1.50. Will a 26 x 1.95 tire fit on it?
Most mountain bike rims are marked 26 X 1.5. Best way to know for sure? Consult your LBS - local bicycle shop. Depends on the inner width of the rim.
What tires will fit on my mountain bike rims?
The bike I have is the 2007 GT Zum 4.0 currently it has the City Slicker tires but I would to put mountain bike tires on it for off-roading. The tires are 26 x 1.5, but mountain tires I see are larger than 1.5, like 2 or more....will those sizes still work? will I need to get larger tubes also?
Can 26 x 1.5 tyres fit on 26 x 1.3/8 wheels?
No, they are different diameter. A good rule to follow is this: If a 26" tyre displays decimals as the width then it can only be replaced with other tyres that also display a decimal width. If a 26" tyre displays a fractional width then it can only be replaced with other tyres that also display a fractional width EVEN IF THE DECIMAL AND FRACTIONAL NUMBERS ARE EQUIVALENT. There are some additional numbers molded on tyres. For example, your 26x1.5 tyres will have a set of numbers that show 559-38 or 38-559. This means the tyre bead is 559mm in diameter and 38mm wide. A 26x1-3/8" tyre will have the numbers 590-35 or 35-590. See the difference?
The diameter of a wheel of a bicycle is 49 cm. How far will it travel in 50 revolutions?
diameter = 49cm;radius = diameter/2 = 24.5cm;circumference = 2πr ≈ 153.94 = 154cm1 revolution = 154cm50 revolution = 7700cm = 77mI hope I am correct.
Can you put road bike tires in a mountain bike rim?
You can buy tires that are more suited for riding your mountain bike purely on the road. But you can't go out and buy a tire that's meant for a road bike and put it on your mtb because I think road bikes do have different sized rims and I think your rims would be too wide to fit the narrow road bike tire as well. There are loads of different 26" mtb tires available out there. One thing to look at is the tread type and pattern (ie smooth to very knobbly). The former being better on the pavement and the latter offering better grip on dirt and loose conditions to varying degrees depending on the tire and it's tread pattern. The other consideration is the width, which is generally designated by the second number. For example you can buy a 26 x 1.95 which is narrower compared to 26 x 2.2 or 26 x 2.5. Basically as long as you're not currently running super beefy rims designed for downhill bikes and you go and by a "slick" tire that's meant to be for a mtb not a road bike then you should be pretty right.
Putting different tires on a mountain bike?
Schwalbe Snow Stud or the new Winter use the same low rolling resistance compound as their professional road bike tyres which means they are fast and easy to pedal on the road plus are happy on snow plus ice and of course will be happy off road too. Run these mainly on the road and have found they have less drag than standard non puncture proof slick road tyres. Slick tyres are fine in the dry yet have found them useless in heavy rain and bad weather such as snow. These have a high level of puncture protection too. The best slick out there is the Schwalbe Marathon Racer as it will match the performance of any quality road bike tyre plus has a four season tread as well plus also has a high puncture protection level too.
If the diameter of a cycle wheel is 70cm how many times must the wheel rotate to cover a distance of 5km?
I’d just want to add the engineer’s view to the already given mathematical answers.A 70 cm wheel has the circumference of π x 70=2.2079 m.However, since it is a bicycle, we can assume that somebody is actually riding it.The weight of the rider will make the tyre to compress slightly. How much the tyre is compressed depends on the weight of the rider, where on the bike the rider is sitting, the width, profile and stiffness of the tyre sides and last but not least the inflation pressure of the tyre. That’s hard to calculate, but easy to measure. Assume the compression is measured to 10 mm. This means that we in reality have a 68 cm wheel (beacuse its radius is now 34 cm) so the circumference is 2.1363 m4.4 km / 2.1363 m = 4400/2.1363 = 2059.7 times.However, since this is the engineer’s view we only have two significant digits available, the engineer’s answer should be 2.1 x 10^3 turns, assuming 10 mm tyre compression.
For same speed, do vehicles which have wheels with larger diameter cover more distance than those with smaller wheels?
If by 'speed', you referred to the speed which is shown by the speedometer, then YES.The speedometer is caliberated in such a manner that the readings are always independent of the diameter of the wheels. With larger wheels, you are actually covering greater distance within the same time and that too at a greater speed.Above figure shows that the bigger wheels travel an additional (2 x pi x r) as compared to the vehicle with smaller wheels, in the same amount of time.From the relation,v = rwhere, v - linear velocity, r - radius of the wheel, w - angular velocity of rotationThe angular speed remaining constant, if the radius of a wheel increases, it's linear velocity also increases. I assume, we are running in two similar vehicles, but with differently sized wheels. For example, if two persons are travelling in two different vehicles but one is with bigger wheels than the other, at same speeds (say 40 kmph). The person in the vehicle with bigger wheels is travelling at a greater speed, and he will be like,"Hurray....Travelling at 40, feeling 50!!! 8-)'If by 'speed' you referred to the linear velocity of the vehicle, then NO. Any two vehicles travelling at same linear speeds will cover equal distances in same interval of time irrespective of their wheel diameters.
