Casing fibers look damaged, some broken threads.. it appears..

1. Stop using heavy duty tubes, heavy duty tubes ain't. Waste of money.

Either . . .

2. Use a tire that had a kevlar barrier built into the tread (think Vittoria Rubino Pro) for example along with a regular tube.

OR

3. Use a kevlar tire liner with a regular tube.

Understand that when using a kevlar liner, they hold up best and last longer if the tire is kept inflated and in constant use.

The rest is simply a matter of paying attention where you are going, watching out for and avoiding that which is clearly not a good place to go when riding.

Understand as well that cleaning your tires is a regular part of bicycle maintenance. You're supposed to do a quick inspection after every ride to remove pieces of glass, staples, tacks and thorns that have sheared but still remain in the tire. As the tread wears down, they will continue to be pressed inward and become a later threat.

That tire looks done. Pumping to high pressure can result in catastrophic explosion.

Those are not your average thorns. I'd suggest using sealant inside the tubes as well as a tire liner. I don't think heavy duty tubes or tires will help prevent punctures from those kinds of thorns, and they'll just weigh you down.

I’ve mounted Greentyre’s solid tires - also supposedly in the 700C size - onto 630mm rims. It wasn’t noticeably more difficult than mounting them on the intended size.
I’d assume Tannus would behave similarly.

For those still suggesting rubber, see post 25. That's already done.

As far as the nipples are concerned, no, the threads don't match. It took me a half hour on line to learn more about spokes and nipples than any of a dozen shops I called this morning seemed to know. 2 of them (on the opposite ends of town) said they did have 15 gauge nipples in stock, so I rode my motorcycle over 40 miles, through Phoenix traffic, in AZ heat, to find that one place had them but with the new threads, and the other didn't really have any after all.

I don't feel bad about shopping on line anymore.

Might also try asking on ISO thread with as much info as possible. .

Sorry, what is ISO thread?

That tire is probably damaged a lot more on t he inside.

Here's an image of a tire that has similar looking damage to yours.


Here's an image of what's under that section of tire.


I wouldn't ride it.

I rode it no farther than back home.

With my bad tires or worn out tires i cut the tire beads before tossing them and that way no scrounger will try to use or sell them used.

Okay...an update...and a new question. I ended up just buying all new spokes and nipples. I was having trouble truing the wheel and the spokes were sticking up through the nipple a lot, so I took the wheels into the shop. The shop guy said I bought the wrong spokes. (too long)

I had carefully measured a spoke to be 298mm. He said I needed 296mm on everything but the non-crank side of the rear wheel. Okay, to be sure, I went to 295mm and bought 54 more spokes. All is well, now, spoke-wise.

So I also bought some Slime tire liners. I had no idea something like those could be such a headache to install. Has anybody got any suggestions to help get those in place, and keep them there? I was wondering about rubber cement...?

Also, what is safe to use to make it easier to install a tire. On both front and rear wheels the valve stem is crooked, but the tire & tube will not budge the half inch on the rim it would take to straighten the stem. I tried soapy water but no help.

You could try a few points of rubber cement for the tire liners. Also you might try covering the ends of the liners with duct tape. They can rub a hole in the tube.

As far as the valve stem, remove one side of the tire and straighten. You will wind up doing it on the road when it causes a flat. Its easier to do at home.

I've had good luck for several years with "Mr. Tuffy" tire liners on my folding commuter bike. No problems with the ends causing flats, though there would seem to be no down-side to using a little duct tape.
I place 1" sections of double-sided foam tape rated for "outdoor" use at regular intervals (8 pieces in all for a 20" tire). I use these on my "winter" bike because the studs on the tires eventually wear through the kevlar belts in the tire carcass and cause flats. These liners are extremely tough and get me an extra season or two from the tires; I haven't had a flat in years.

I second these.

Well, 2 sided tape doesn't seem to work. So, looking for some rubber cement, or anything that will actually secure the plastic strip to the center of the tire. I had some stuff that's made to seal car tires and is very expensive...like 42 bucks a quart. Used it on my motorcycle and a friend was going to split the cost with me and use it on his bike, too. He ended up selling his bike and giving the goop away with it. He never did pay his half. The stuff would have worked, for sure.

greatscott

Are you saying that Cleveland is thorn country? So what type of thorns are there?

greatscott

You can also sand down the edges till it's very thin and that will prevent the Mr tuffy from rubbing a hole in the tube...OR...you can buy RhinoDillos that cushioned the one edge of the liner to prevent the chaffing. The RhinoDillos are every much as tough as the Mr Tuffy.

A suggestion that isn't the tire you should ride but one that might stop a few thorns from even getting started. Tiresavers. Small wire and plastic tube thingies you attach at the brake bolts that ride on the tire and knock objects off as the tire rolls past. There have been at least one recent thread re: them. I think they are still made and if not, they are still out there, plus you can make your own with coathanger and tube from a hardware store. Not ideal. You here them and they spray the bike in front of them with road dust, but they can stop a lot of flats, Many of used them back in the days of sew-ups. (I'd wear through the wire and rebuild them with coathanger.)

I'll go look for those posts and come back if I find them.

Ben

Edit: Well that was easy? Typed in "tiresaver" and first post:

Now I would bend the wire over the tire a little more so it fit the tire better.

If the tape doesn't stick to the tire liner, you could try the "Mr. Tuffy" brand... the "Slime" brand may have more of a non-stick surface. If it's the tire the tape won't stick to, there may be talc or other similar material on the tire.
Thinking about it, I'm surprised someone doesn't make a sort of "pre-formed" molded tire liner that would stay in place...

There are some plants/bushes that produce thorns and that are in the NE. When in Cleveland and on one of my first MtB rides at Punderson Pk (before they outlawed bikes from their trails, a long time ago) I got a flat just as I was about back to the car. Turns out I had 7 woody thorns in the casing.

That family i mentioned that suffered many thorn flats, until we figured out the thorn bush along their one side, had bushes that are pretty common. Little stiff thorns about 1/4" long and act like a sewing needle to weave between the casing fibers. Andy

Not really. Just making sure that someone doesn't unknowingly try to use a worn out tire that would be dangerous to use.
