Arc length - connected wheels?
Arc length radius x angle in radians 150 degrees 150 pi / 180 radians 5/6 pi radians Because of the belt, both wheels move by the same arc length. If the small wheel angle is a, then 5 x 5/6 pi 2 a a 25/12 pi radians 6.54 radians
If your bike has ordinary spoked wheels, then there are already tubes installed. Unless the tires are dying of old age and have never been changed since new, the rubber around the valve stem is dry rotted or they have been patched before, then the old tubes should be ok. If for some reason your bike has air tight wheels, then do NOT install tubes. Every manufacturer has went to tubeless tires on just about every wheeled machine there is for a very good reason. If you run a nail through a tire with a tube, it is going to lose air VERY quickly and you won't even have time to pull off the road before you're riding on the rims. A tubeless tire will seal around small objects like a screw, nail or piece of wire and will either leak very slowly, if at all. A few years ago I had a sheet rock screw run through my rear bike tire and it took it 3 days to go flat.
This Site Might Help You. RE: Do I need an inner tube on a tubeless motorcycle tire? I pretty much know nothing about tires. I have tubeless tires on my 99 Yamaha V-Star 650. The mechanic mentioned to me that I should get tubes to put in the tires. So, how does that work? Would one just remove the valve stem and place a tube inside of the tire? I just thought it was odd the.
Mark is on the money. If you have spoked rims you have to have an inner tube unless you are riding a Harley Davidson with the specially designed inner piece to allow you to run them with tubeless. With the spoked rims there will be an inner rubber strip that gets laid over the spokes inside the rim, and an inner tube. When you change the tire you will need to replace the other two pieces as well. When you do get a tire changed make sure there are not protrusions on the inside of the rim that could damage you inner tube.
