That's where I ordered my CO2 inflator from.Really works well for topping up tires out on the road.They're only 6.00 and they come with a CO2 cyl.also.I would recommend them since they're so light and don't take up any space to speak of.

 

Ped tires should come off as easy as bicycle tires. Bicycle tire irons work just fine. Be sure you begin to remove the tire near the valve first and make sure the opposite side is in the well of the rim. When installing tire, begin opposite the valve and finish with the area close to the valve. Again, making sure the tire is pressed into the rim well. You can usually install the tire without using levers if you have it positioned in the well correctly. If the instructions are not clear, try to find someone who has repaired bicycle tires to show you how. A regular $1.99 bicycle patch kit from any discount store works fine. While you have the tire off, clean the inside of the casing and rim and make sure you have removed whatever caused the puncture. Sprinkling some talcum powder on the tube will allow it to slide in the tire and avoid kinks. I usually pump a few pounds of air into the tube after installation then let it down again and check for kinks. Press the valve stem into the rim before inflation to make sure that the valve stem base is not trapped between the tire and rim. If you have mag rims, use a piece of shoe leather or similar between the lire lever and the rim to avoid scratching it. It really is a piece of cake once you get used to it, your ped tool kit should include a patch kit.

 

Tire inflation, (weather it be for a Car, truck,motorcycle, or moped) is always what the manufacturer of the vehicle recommends. Not what the tire states. Tires will generally have a maximum tire pressure. For mopeds I run 30 to 35 psi in the tires, depending on the riders weight and the terrain they will be riding on. Tomos recommends 26 psi for the front and 32 psi in the rear. (cold pressures) for most of their models . (not sure about the revival.).

The 2.25" refers to the "ballooning" of the tire. A 2" isn't as wide as a 2.25". As long as the 2.25 won't rub you can use them. I wouldn't recommend using bicycle tires. Bike tires are not rated for the speed of a moped. If you deside to try bike tires note that bike tires are measured by the diameter of the inflated tire, while moped and motorcycle tires are measured at the diameter of the rim.

Tire mounting technique can make the job a lot easier. Mount the bead of one side of the tire into the middle of the rim (not the side of the rim like it will be when the tire is inflated. By doing this you will be able to pull the top of the tire over the rim. Insert the tube and inflate it to get it even around the inside of the tire. Make sure the tube isn't twisted. Once the tube is even around the inside of the tire, deflate it. Again, put the tire bead in the middle of the rim and work around to the top and slide the top of the tire over the rim. When you figure out what I mean by the "middle of the rim" the tire will go on and off much easier. Do not use tools that could puncture the tube. Dish soap can be used as a lubricant on the tire.

The difference in sizes is that vehicle tires are measured in RIM diameter, and bicycle tires are measured by the outside diameter of the tire.

If you do take the tire off make sure to feel the inside of the tire for a sharp object stuck in the tire.

Did you put some spit on the valve opening to see if a bubble blows up ? Brandon was talking about a valve core removing tool. It allows you to remove the spring and pin in the middle of the valve stem. Sometimes if the valve core is not tight inside the valve air will slowly leak out. To check if this is the problem, spit on a finger like bruce said. If air is leaking out from the valve, get one of these tools, the cost about $1 at a bike or car store, put it inside the valve and tighten.

I have somethin a lil better than that - product called No-mor flats, foamcore solid inserts, and the model # 20B8 fits Tomos moped wheels. Not bad at all for like $17, especially given how much of a pain in the arse it is to replace tubes on Tomos rims with Cheng Shin tires on em. (For whatever reason, Cheng Shin tires seem to fit closer, making tube replacement pretty hard.) Walmart

Use BELL Self-Sealing 20" Tubes, they are the correct size for your wheels, and I have found them in fact more durable and effective than standard moped tubes, for the same price. They run about $6.95 a pop, but you can buy them at Wal-mart, so they're easy to find and no shipping charges. Be very careful putting em in tho, it's damn easy to pinch em.

never use bicycle tires on a moped,

The product you want is called No-Mor-Flats, and you do *not* want the 16" model, since moped rims are measured differently. You want model 20B8, it is the correct one for 16x2.125 moped wheels, which is what Tomos, and some other brands, use. Follow the instructions exactly, and be careful to seat the bead of the tire correctly, it's more difficult since the material doesn't compress as well as inflated tubes, particularly with Cheng Shin tires, as the bead on them is harder to get right than normal tires.

The correct term is Tubless Inserts. Because they are not really tubes. They are very high density (almost 'solid', but with some give to absorb road shock) foam rubber. A friend of mine uses them in his bicycle. you can run over nails and glass and all kinds of stuff and not have a blow out. The down side is they are heavier than a rubber tube full of air. They have basicly the same give as a tube with about 40 psi air pressure. He weighs about 320lbs (!!!) and they are 20" bike (same as 16" moped/motorcycle size) tires. It one of those weird-ass 'recombinate' seat bikes. You sit back like on a recliner and pedal with you feat facing forward. you sit right over the rear tire. It's the ONLY choice for him...

First of all, is it a mag wheel or a spoked rim? If it has spokes, make sure that the rubber chafing strip is still present. The chafing strip looks like a wide rubber band that goes around the circumference of the rim and keeps the tips of the spokes from piercing your tube. If it is not there, go to you local bicycle shop and see if they have one to fit your rim. I have even used a narrow piece of duct tape in place of a chafing strip with good results. If you have a mag wheel, then there is no chafing strip, but make sure there aren't and jagged or rough spots on the circumference of the rim that the tube will be in contact with when inflated. When you install the tube, make sure that the valve is nice and straight and not crooked. Also, you are supposed to use tire spoons or someting similar, to remove and re-mount the new tires. If you use a screwdriver, you are more likely to damage the rim (especially mag wheels) and pierce the tube.
You can also use Mr Tuffies. They're strips that go between your tubes and your tires. You can pick them up a bicycle shops. I think they're made from Kevlar. Foam inserts seems like a silly idea to me.
 
I've tried it with bicycles before...it's great for taking care of small holes you might get from things like tacks, or those little goathead weeds that stick into your tires. I was riding a road bike with "the goo" in the tires once, and I hit a goathead. I pulled it out and kept riding...that's how well the stuff worked. I don't know how well it would work with moped tires though.
If you keep your ped outside, you should take about 1/2 the air pressure out of the tire, to keep them from cracking. it'll only take a couple minutes to fill them up in the spring, and you won't have to buy new tires.
