Things I learned during my first tire change.

Post by greybear » Mon May 15, 2017 1:25 pm

1; Workplace matters. I tried wrestling the tire on the floor, I tried wrestling on a bucket. The tire won both matches. Then I placed the tire on the sidecar spare tire rack. This proved to be just the correct height to break down the tire.

2: Tools matter. I was having trouble breaking the bead. Happened to be in Harbor Freight looking for something else and saw a 12" deep c-clamp with a 5" opening (45919). <$10 and worked great to break the bead. I tried one of the smaller tire irons which look like a modified screwdriver. No joy. Then I hit myself up the back of the head because the company I work for manufactures and sells tire repair products. I borrowed a pair of Ken-Tool 32109s from the training shop.They are only 9" long but have just the correct bend to coax the bead off the rim. Bead Breaker also helps.

3: There is a reason some instruction say to start breaking the bead 180 degrees from the valve stem. I didn't on the first one and damaged the tube at the base of the stem.

4: A small bronze toothbrush works great for removing minor rust from inside the wheel.

5: Dish soap and water can help lubricate things up very nicely. A little too nicely. I added disposable nitrile gloves to my tool kit.

6: Tire Talc or baby powder helps lubricate the assembled wheel inside. However try and get as much of the dish soap mix out BEFORE you add the powder.

About 1/3rd of the way through I thought maybe I should have paid the local bike shop to install the tires. However I figured this was something I needed to learn and I wanted to lube the bearings anyway. So once I had the side car wheel and the spare off for bearings changing the tires myself seemed logical.

Horror Fright sells tire irons that are pretty nice.

For $6/each, get at least 3. They are 24 inches long. If you need a bigger tire iron than that, you are doing something wrong. :wink:

Another thing you didn't mention, but probably had to is to continually break the bead on both sides of the tire. If you do, then you'll only have to struggle with the last 1/2 inch or so (applies to Duro 308s)

After surfing the web for suggestions I used the "Dunlop" method. After changing many car type tube tires this seemed odd but worked well.

Huh, I've been using the Dunlop method for years and didn't know it!

The only thing I found "wrong" about them is that they're too long! Save yourself $6. Buy one and cut it in half. :wink:

edit. And while you're in town, stop by a bike shop and buy a "bead buddy" to hold that bead down while you work around the rim

I'm cheap. But the $10 they charge me at the jiffy lube seems like a deal to change out a tire on the rim

:cheers: Me, too for the most part. Only recently moved to the No-Mar bar method.

I have always used a clamp to hold the tire in towards the center. One of these days I need to make or buy a Bead-buddy.

Brake rotor makes the process easier. I've also never taken both sides of the tire off the same side of the rim. The second side is always so easy, I'm not sure one way is better than the next.

One of these days I want to try the zip tie method on a Duro or similar stiff sidewall tire. Plenty of vids on YouTube if you are curious about it.

If I could have had the tire changed for $10 I'd have paid the price. Here only bike shops are willing to tackle bike tires. They typically charge $25 for tires bought there and $35 for tires you bring in. So for $70 for mounting two tires I decided this was a good time to learn the process. I've still to pack the bearings, any tips on that?

Put a glob of grease in the palm of your hand and holding the bearing in your other hand, push the side of the bearing into the grease until it squeezes through the bearing. Turn the bearing a little and squeeze the grease through the next section of bearing, continue until you have gone all around the bearing and filled it with grease. It is most important to get the grease inside of the bearing, not all over the outside.

I bought a tire changer thing from HF Even have adapter for mc tires. But never tried it. Guys at the jiffy lube (boss and asst). Cut me slack on inspections etc cause I always tip em $10 to $20. I think they do work for me off the books and pocket tire changing money. I don't care. Works for me. Unless I have somebody who will cut me some slack on annual safety inspections I'd have to tow the ural and samurai back and forth to Canada every year. If ur vehicle "breaks down" outta state when inspection due u can get a one year waiver

Lots of videos on line. Search packing bearings by hand. Or. Greasing bearings by hand

I have a bearing packer that I've used for decades on trailer and camper bearings. So I was thinking more along the lines of disassembly and reassembly of the DNEPR bearing pack.

good product called RU Glide helps getting the tire to slip on very easily. It's slippery at first, but gets sticky when it dries, so the tire slips on nicely, but the tube won't spin once it's dry. Napa sells it.

First, clean the bearing in clean solvent. I actually use two or three different containers of solvent. First to get the majority of the old grease off. Second to get it cleaner and third (usually in a white container to see any dirt) to make it squeaky clean. Then blow it dry with compressed air. DO NOT SPIN THE BEARING WITH COMPRESSED AIR!!

With it clean, packing the bearing is a piece of cake. Put the bearin in your hand and put a glob of grease in there. Now just squeeze the bearing in you hand smoosh the grease into it. Turn it occasionally, squeegee the grease off your hand with a clean finger and put it back into the bearing and squeeze some more. If you wear surgical gloves, you just strip the glove off when it is packed and do the assembly. Much easier than wiping the grease off you hand.

Grease all the surfaces inside the hub to prevent rust.

That's all there is to it.
