    Tire slit anything to worry about?

    New to roadbiking so this q is pretty basic. I had a flat the other day and found a small gash in the sidewall. Is this anything i should worry about?



    Thanks!

    Reinstall the tire and inflate up to pressure. If you see any sort of noticeable bulge then the tire is done.

    Reinstalled the tire and it looks okay to me. There isnt much of a bulge but the tear barely runs into the main tread. In your experience, would it cause any concerns? Theses are pretty new Michelin Pro4s. Would hate to junk them so soon but safety first.

    Thanks.

    Actually, the advice should be reinstall the tire and inflate up to pressure. If you see any sort of noticeable bulge then the tire might be saved with a boot. If it still bulges with a boot installed then at a minimum it will wear faster at that point. If the bulge is significant, then the tire is done.

    I suspect that the cut is only skin deep and does not reach the casing. If that is true then there will be no bulge and no need to worry. If you do worry put some Shoe Goo in the slice.

    I would boot it with glue and a tube patch and keep an eye on it. I'd also put it on the rear wheel as a safety measure too.

    Man, that looks 'borderline'. I guess I like Newnan3's advice the best. That sure would be in the back of my mind bombing down hills at 50 mph or heavy/tight cornering.

    I would simply run it as is. IMO, if there's no danger of the tube protruding booting does nothing. Attempting to glue the cut accomplishes nothing of consequence either.

    Tough to say what I'd do just from pictures and not feeling it but if I used it I'd definitely put it on the back not the front.

    I think you're scare mongering. With no real bulge at all, there's no "betting on a crash" from that tire failing. Tires get nicks and cuts all the time and yet somehow we all seem to live through it.

    So perhaps I am being a bit too cautious, but then again I had a sidewall blowout on a Pro 3 on a fast descent that could have ended it for me.

    It was about 40 MPH and the rear blew out. I was lucky I was able to regain control and stop. Every time I see a Pro3/4 with a sidewall issue, it just brings back that memory.

    Re: Tire slit anything to worry about?

    I added 3 layers of tyvek bonded with shoe goo and another layer of shoe goo on the outside. The slit is now bonded. These are inflated to 110psi.

    However, after reading your posts, I did go ahead and order a new tire. They are priced nicely on PBK right now too so it works out. It will take a week to get it so I'll ride this repaired tire conservatively for now.

    Thanks everyone.
