What did I do wrong with this tire? Was it my liners?

I was riding along on my Bianchi Pista andI heard a thumping noise in my rear tire.
I got off and saw a bulge on the side of the tire, near the rim and so big that it was hitting my frame.
It was freezing rain, 37 degrees, and I had 5 miles to home so yes I got on (no spare) and kept on riding. The bulge was so big the tire was jamming in the rear frame.
I got off and a few seconds later the tube blew. This is what it looks like. now
I used this tire for at almost 1000 miles with no issues. . I had Mr. Tuffy Tire liners inside .the tire. Tire pressure was okay, not high or low.
What did I do wrong? The Tire was a Schwalbe Durano, which is supposed to be a really tough tire. I only had it for three months.

Does every bad thing have to have a cause and reason? Change it and ride.

Or focus camera and try again!


Edit:
Excellent pic now. But why haven't you changed it yet for your next ride?

Make sure that your brake pads don't contact the tire at any point in their travel.

+1. Given the location and length, thatís the most likely reason.

+2---Or you got a defective tire. But the last time I saw that scenario it was the brake pad touching the tire. Good luck

Oddly enough I had a beach cruiser bulge a couple of tires. I think, and I mean think, probably a few pounds low on pressure and the garage lip caused it.

I'm also voting for brake pad hitting the tire. And jesus...how can you take a photo that bad w/ the quality of phone cameras these days? It's almost like you tried to screw it up.

I have no rear brake. So it was low tire pressure?

No rear brake. I am assuming it was low tire pressure. Those tires are rated for 100 psi.

You should see some of my photos...I am terrible, granted my phone is rather old (we have moved forward 6 phones in the time mine has existed.

It could have been those hard tire liners and not enough pressure. I certainly wouldn't want to run things like Mr. Tuffys in any of my tires. It also could have been a defect but defective Schwalbe tires are few and far between.

If I am really desperate to not have flats I will make sure I have installed a good rim strip properly, used decent tubes and a good puncture resistant tire (like a Continental Gator HardShell) in the widest width I can fit on the bike and make sure it is at the proper pressure. I would also check the tires regularly for any wear or damage and replace them as needed. I would also make sure to have brakes on the bike (set up properly) just so I can stop instead of potentially wearing out a tire by leaving skid marks in my undies.

<grin> You must be younger than 45 or are one of the few that doesn't need readers <grin>

I quite often am guilty of snapping pics that don't auto-focus on the right thing and don't know till I examine the pic later when I have access to my reading glasses.

Riding any distance with an underinflated tire can cause this to happen. Narrow tires need a lot of pressure, and unless you are checking with a gauge you might not even realize you are underinflated.

I also have seen defective tires where the sidewalls where it meets the bead cannot handle its rated pressure long term, but that is rare, and was generally only one manufacturer that you would most commonly get it (Specialized), in my experience.

I'm guessing the tube was caught under the tire bead which started the bulge and you kept riding it which caused the tire/tube to hit the frame causing damage to the tire and blowing the tube. Just a guess though. Check your rim for any sharp edges or gouges or other damage, mount new tire and make sure the tube is not pinched under the bead and be done with it. It could possibly be a defective tire too so you should contact Schwalbe with a photo of the unmounted tire and see what they say. Who knows, you may get the tire replaced under a warranty. New photo looks much better.

My guess is it's a bad idea to use a stiff cold liner. Are there really thorns about in winter?
Let's see the inside of the tire. Bound to show more than the outside.

I've been using Mr. Tuffy tire liners for years in my commuter bike's tires. I have never had a flat since I've been using them.
This is my "winter" commuter, so the liners probably can't be much stiffer. Ironically, the reason I use them is because the studded tires ("Marathon Winter") on my bike eventually have "wear-through" of the studs into the inside of the tire. This would (and did) cause flats, and there's not much worse than a flat during a snowy winter commute. The liners prevent these flats, do not cause their own flats, and extend the service life of the studded tires by at least one or two seasons.

EDIT: Here's an image of the inside of a Marathon Winter tire near the end of its service life; you can see why a liner would help!

This is what salt and slush do to a studded tire after a couple or three winters. It might last another season with a liner.
