Picked up some glass last night.... Can I just replace the tube, or is this tire shot?
Thanks

A small dab of shoe goo will hold that together. I would probably try that first, then try a tire boot (my preference is a piece of a Tyvek envelope like FedEx uses). If they both fail, then replace the tire.

I just googled shoe goo - never heard of it, but it sounds cool. "dries to a waterproof, flexible rubber"

Any idea where I can buy the stuff?

Any sporting goods store or the sporting goods department of K-Mart or Wal-Mart will have it. It was originally developed to build up worn soles on running or other athletic shoes but it's a pretty good glue/sealant too. Another possibility is a drop of Super Glue to close the cut.

BTW, If the cut has gone all the way through the casing cords and can be seen from inside the tire, I recommend discarding the tire.

I think the Shoe Goo and a boot that adheres to the inside of the tire will allow the tire to be used even if the cuts go through the casing.

I got my tube of Shoe Goo at:

I was on ride last week and picked up a similar cut. It was fairly easy to fix with a boot and a replacement tube. I got home OK but have since changed the tyre.

If it's just the rubber, wouldn't worry about it. Go with the Shoe Goo if you want; might limit it peeling back more. But the rubber is not what contains the pressure; the casing does that. If the casing threads are damaged, replace it.

My test is to replace the tube and reinflate the tire.

If I can feel a bump or if the tire tread makes an ess curve, then some of the tire cords have been cut and the tire is shot.

If a tiny bubble of inner tube balloons through the tire, I boot the inside of the tire with a piece of duck tape to hold in the inner tube.

Ok... I think I'll try repairing it just for the sake of stocking up on Shoe Goo and tire boots. If it doesn't work... oh well - it's a cheap Panaracer Pasela, and I got about a 1000 miles out of it.

Looks OK to me. The cords are not cut so the strength of the tire is unaffected. Filling the cut with superglue, silicone, or shoe goo might help prevent debris from getting in the cut, but otherwise, it's no problem to ride.

A closer inspection reveals:



Are the cords the closely spaced lines that the cut intersects, or the lighter lines spaced about a half inch apart that the cut just missed?

Do this and report back.

Tread only cut can be fixed with super glue. Thru the casing it's hasta la vista.

The cords are the closely-spaced lines. It looks like three of them are cut. You can try Retro Grouch's suggestion, but to be on the safe side, replacing the tire would be best. As has been said here before, a new tire is cheaper than dental work!

My experience matches ZachS.

Depending on how rough you ride and your road conditions you can boot that one and not run it as a race tire. Personally I would, double tyvek it or cut a piece from a plastic bottle or milk jug (sand the sharp edges down) in conjunction with shoe goo. Keep the goo inside the tire/lower than the tread. If it goes outside it can pick up and hold debris due to its softness. Check it before and after rides. Have a spare tire ready to swap at home. Make sure you take a pump, spare tube and boot with you. If you are really concerned or unsure take a foldable spare. If you are concerned, you should maybe ride with a foldable spare anyway. It looks like you have 3-500 miles left in that tire.

a folded 100 dollar bill works better. it just matters with the inside cuts. like shoe goo, or a tape of somekind, and i would run it in the back... not the front.

If it is just a Pasela, why not just buy a new one. 10 or 15 bucks depending if they are on sale.

Put a Park adhesive tire boot on the inside of the tire and you should get many more miles out of it.

Yeah, I find that 3M Fastak Super Weatherstripping Adhesive works really well to glue old Tyvek race-numbers to boot those cuts. Follow the instructions on the box and glue a dime-sized Tyvek patch on the inside of the tyre over that cut. Then glue a quarter-sized Tyvek patch on top of that. No big bumps, no thick boots that move on the inside that can cut your tube. The repair ends up being just about as strong as the original casing. If it's over a 1/4" cut, you can even lay a third layer of Tyvek for extra reinforcement. Then dab a little ShoeGoo on the outside and you're back on the road!

That tire looks to me as if there are at least 5 damaged cord, but there is a second ply running in the opposite direction which is also dmaged at least that much. I woulddn't ride that tire, but I might boot it with duct tape and carry it for a spare.
There is a lot of bad, even dangerous, advice in this thread.

That depends what kond of patch you use. A Park boot, or duct tape, or Tyvek might work, but a flexible patch like a Rema is designed for tubes, and is virtually worthless as a tire boot.

A boot os way more effective if it extends the full area between the beads. The damaged cords extend from bead to bead, and so should the repair.

A $100 bill does work better, because you will not forget to remove before it disintegrates.
