How many people does it take to change a tire?

It depends on the location where you live.  I live in a large city on the west coast.  For me, it's a one person job, rarely do you have someone stop to help.  \n\nBut in a smaller community where most people know each other, it's rare that you'll spend much time on the side of the road without someone stopping to ask if you need any help.  And sure, there will be times when there are more hands than are helpful. But that's part the part that makes a menial task like changing a tire a little more fun.  One guy does the work, the rest hang around and crack jokes.

You need to make a trip to your local bike shop, hardware store or department store. There you need a tire repair kit. \n\nSome things this kit should have are:\n\nRubber cement\nPatches\nsandpaper or a scrapper\nTire levers (one end that is tapered and slightly curved. The other end is usually hooked so that it can be hooked around a spoke)\n\nStart by removing the wheel.\n\nNow you need to remove the tire from the rim. Start at the point opposite the valve. Sometimes you can slghtly lift and pull the tire sideways off the rim. If that doesn't work, slide a lever between the tire and the rim and pull the lever down and hook it around the spoke. Use the other levers to work the tire loose till you can remove the tire and tube from the rim. Be careful not to pinch the tube with the lever or you'll create more leaks.\n\nRemove the tube and inspect the tire. You are looking to see if there is anything like a tack or glass in the tire that caused it to go flat. If so remove it or fixing the flat will be useless. Also look to see if the tire is damaged. If you have a hole or tear in the tire you need to replace it.\n\nNow for the tube. Get a bucket 1/2 full of water. Pump the tube full of air and submerge the tube in the water, at the valve, slowly turning it looking for air bubbles. Once you locate all the bubbles remove the tube and dry it off around the leak. If you have more then 2 leaks you should replace the tube. I never patch a tube any more then 2-3 times. Rough up the rubber around the hole with sand paper or the scrapper. Make sure you rough up an area slightly larger then the patch you intend to use.\n\nSpread some rubber cement in a thin layer on the tube. Peel the protection off the patch being careful not to touch the surface of the patch. Place the patch onto the cement on the tube and rub it onto the tube till the pach is firmly in place. A tire lever works good for that. Remove the top protection (If present). Wait 5 to 10 minutes for the cement to cure. (Read the cement to make sure of the set up time) Check it again with the water to see if you got the leaks patched.\n\nRelease air from tube. Put tube in tire and tire back on rim starting at the valve and working  both sides away from the valve onto the rim. Do not twist the valve sideways while doing this. The valve should remain straight with the spokes. Near the end you might need to use the tire levers to finish putting the rest of the tire back on the rim.\n\nOnce you have the tire back on the rim pump it up and listen for escaping air. If you hear none put your wheel back on your bike.

This question is too vague.  But I can tell you that tires will make the biggest difference both cheaply and quickly.

People can and do change.\n\nBut don't set your watch to it.

With a ticket, for timeing situations (1hr in a 15 min parking area) they frequently mark a tire with chalk.  The chalk wears off quickly on the road but not if you are moving just across the street.

Fill your car tires with it. It's all the rage in my part of the country and it'd be nice to do the following experiment. One week do 4 nitrogen tires, the next 4 filled with air, the next 2 of each and repeat for a couple of months, just refilling the same tires differently. Keep track of mileage over this time and see if filling your tires with nitrogen makes a measurable difference.

Thousands, It's complicated and unless your a good design engineer with Outstanding math skills, Machining skills, Metal specification knowledge. It is almost impossiable, That is why it takes the automakers on average of fives years to design a new engine and thats using teams of up to 40 to 100 people.or more. and modern CAD programs.

There was a change of regulations in 1998 that stated that tires must have grooves, 3 for the front tires and 4 for the rear tires, in order to cut grip and cornering speeds. Up to 1998 pilots used slicks. From 1999 the number has been put to 4 grooves on each tire, but the FIA seems to say, in the rulebook for 2008, that F1 will return to slicks. Probably a bid to increase the number of overtakings, and by that the TV rating. Because overtaking maneuvers done "heroically" are the biggest eyecatchers in F1. And Bernie Ecclestone doesn't want to lose money from broadcasting F1.

It is 7.  Jackman, gasman, catch-can man, two tire changers, and two tire carriers.  In some instances NASCAR officals will allow an 8th member over the wall to remove a windshield tear off.

For looks, maybe.  But not for handling.  Manufacturers design a bike for a certain tire size.  Change it and the bike will not handle as well.

If he only had 3 tires, each would go 1000 miles, so it's a 3000 tire-mile trip.  If you divide that up among 5 tires, each one must do 600 miles.\n\nTo show it works, name the tires A,B,C,D,E, and break the trip up into 200 mile chunks.  Here one way to rotate the tires.  Note each one is used for 200 miles 3 times.\n\n000-200 ABC\n200-400 ABD\n400-600 CDE\n600-800 BDE\n800-1000 ACE

Assuming the mass of the tire to be concentrated at the given radius and taking inertia of the tire as m*r*r = 0.099 kg m2.\nAngulare momentum of the tire is (I * w) which comes out to be 9.2664. Torque for stopping the tire = 9.2664 / 1.7 = 5.45 Nm.

Take one lug nut off of each of the other 3 tires, and use them to put the spare on - that way, each tire will be held on by 3. That should get him to the next town, where he can buy 4 more.

Look at the tar macadam widths in the road. They are normally either 8 or 10 feet wide. count how many, add approx 8/10 feet for each pavement.\nOR count how many people you see - devide by 2 !!
