Hey everyone, new here, and also new to riding bikes. After 29 years, I finally learned to ride and after a month of riding, this morning my tire messed up.

I'm still not sure what happened (and forgive me for not knowing the proper names of specific parts)

Here's a picture of the damage, hopefully someone can explain to me what happened and how it can be fixed? Much appreciation. If this is something I can repair myself that'd be great, but if you all think it's best to just take it to a shop I can do that too, I just don't have much money to spare and the only bike shop near me has very odd hours so it's hard to get there at the right time.

Thanks in advance! Happy riding!


not sure how to post images. Here's the links:

I reposted one of the pics below. A portion of your tube is sitting under the bead (edge) of the tire, and is pushing it off the rim. The most common cause is poor installation, but, judging from the looks of your valve stem, riding under insufficient tire pressure may have contributed to the problem. You may find on deflating the tube that it is folded over.
Check the Park tool page on tire mounting: https://www.parktool.com/blog/repair...d-installation and also check a few videos: https://www.google.com/search?biw=14....0.HgKkjPRmbrw

The good news is that this problem will motivate you to learn one of the most basic and necessary skills related to owning a bike. You almost certainly don't have the tire levers that are recommended for removing (but not for installing) the tire. If you have some metal spoons or forks with flat handles and curved ends you can use those instead. DO NOT use a screwdriver or anything else with sharp edges. Some big box stores or hardware stores, and of course a bike shop would have tire levers for sale.

Thank you so much for your reply! This definitely helps a lot and I absolutely agree! I do not want to have to resort to taking it to a bike shop every time something goes wrong, so thanks to your help I can attempt to fix it on my own. Thank you again!

It looks to me in that picture as if the tire bead has separated itself from the tire carcass. In that case you will need a new tire and inner tube

RichieSteel,,

I too have returned to riding and, WOW, have things changed since I abandoned my Schwinn LeTour in 1983. So, I am also trying to climb this very vertical learning curve on modern day cycles. Hey, the new technology is great!!

My current ride is a inexpensive GMC Denali that I bought via Amazon. Didn't want to invest a lot of $$ until I knew I was going to stick to riding again. Well, five months and 1,164 miles later I'm hooked. Gotta say also a lot of upgrades to the Denali (POS). Tires and tubes were the first.

As a returning 'newbie' I'd strongly suggest replacing the tires and tubes that came with the bike. Hey,,, yo butt is ridding on that thin line above those tires.

Just my humble input..... Have fun and remember pedal pressure equates to forward motion....

Yes, I thought it looked a bit odd, should have looked more closely. It does appear the wire bead may have come out of the tire casing, which means the tire must be replaced. There's no need to replace the tube if it did not go flat.

Thanks for all the replies and help everyone! Yeah, looks like I'll be taking a trip to the bike shop to just have it repaired as soon as I can.

One more thing. Bicycle tires have to be pumped up much more frequently than car tires which can go for weeks or months without attention. High-pressure, low volume road tires may have to be topped off every couple of days and lower pressure, higher volume cruiser and MTB tires every week or two. Bike tires are not set-and-forget.

Thanks for the info, I do have a tire pump and I had actually been pushing on the tires every day before my ride to see how tough and full they felt. I had used it on my front tire twice, but was afraid it might burst on me if i added too much. I am definitely a newbie to all of this lol

On that first pic, to me it looks like there is a crack in the rim or a v-shaped chunk out of it. It may just be the lighting and quality of the pic.

If you start from the top of the pic it is between the first and second spokes that are visible on the outside edge of the rim.

Was the bead in fact torn from the tire? Although I can agree the 2d and 3d pics sort of look like that the first doesn't. So it could just have come off the rim.

That can be from running too low a pressure, or too high a pressure. Or a damaged rim. It might also be the wrong type tire for that rim or the wrong size tire.

Was the bike bought used?

It looks like tyre was not mounted fully into rim before inflating.

You need to use a gauge to determine sufficient pressure. Your thumb is not riding on the tire, but rather your entire body.

Indeed it was!
