Tyre Tear ! How bad is this ?

Hi !
After a 50km ride I found this when i reached home.

http://imgur.com/a/wxZ5s#AhNIo

Nothing busted as of now, but how bad is this ? Would this get worse ?
This is a new bike
These are Hutchinson Equinox 650 x 23c, hardly ridden 500 km

The cut is along the cords, not across them, so the tire should be ok unless it's actually through the cords. I can't be sure from the photos. I'd fill the cut with Shoe Goo or similar repair cement to protect the cords from water and further damage.

If the cords are not cut, I'd just ride it.

That's my strategy, with no ill effects to date.

Agree with HillRider. I have used black Shoe Goo exclusively on tire cuts. Just fill the hole with Shoe Goo and scrape flat with a putty knife. To be on the safe side, you might also want to consider mounting the tire on the rear rim.

The decision rests on the condition of the casing. If when inflated to full riding pressure there's no change in width compared with the rest of the tire, then the structure of the tire is still OK and you can ride it. Make a gauge by cutting a "C" shaped notch into the side of a piece of cardboard or old credit card. Match it to the width of the tire and see if the affected area passes cleanly.

If you d0o choose to ride it, be aware that these rarely blowout unannounced. Before failing complete the tire will begin to bulge giving you a telltale warning by way of thumping or squirrely handling. The warning period can be anywhere from a few hundred feet to a few miles, but be attuned to it and don't discount it. Be prepared with a spare if going anywhere far from alternate transport (if you ride tubulars carry an extra spare)

Also if you do ride it use shoe goo, or some other kind of rubber cement or filler to glue the cut closed so the casing stays protected.

This, it's a few bucks to do away with all worry about it.

People keep posting about the risk of riding with marginal tires. IMO the risk is near zero, and mostly a matter of convenience. Bicycle tires blowout routinely both from old cuts and new or unseen ones. Just about everyone who's ridden light road tires for any length of time has suffered a blowout at one time or another, and not many have involved an injury (I don't know of any, either 1st or second hand).

If you consider the risk of blowout as a serious risk, you shouldn't be riding light tires at any speed regardless of condition, and if you think you're safer because your tires look OK you're kidding yourself.

Compared to the other real hazards of riding, all of which we consider acceptable, a blowout ranks very low and should be taken is stride.

In the picture I'm not seeing any signs of the cut bulging open or a peak at a herniated tube. That tells me that no cords are cut and the tube is still safely contained. Shoe Goo it or fill it with whatever filler you like that is compatible with rubber and carry on.

I don't usually fill my small cuts and holes. Like the small one in the same picture for example. But one this big I'd fill just to keep stuff out of it and hopefully avoid it holding onto something that COULD produce a flat.

Yeah, but getting some of these guys to spend a few bucks is worse that pulling teeth. bk

Okay just an update after almost 5 months , the tires are still good to go, the pressure holds and no bulges.
take care

Whew! Did you end up using Shoe-Goo, or are you just keeping an eye on the crack as it was pictured before?

My test is to install a new inner tube and inflate the tire to operating pressure. If I can feel a bump at the cut then I know the caseing has been cut.

Even then, if it's a beater bike, and the bump isn't too big, I'd probably put it on the rear wheel and ride on it anyway. On a good bike, I'll replace the tire.

In making bike tires, casing cords are laid diagonally.. across each other
on the bottom.
