If I can see the inner tube, can I still use the tire?(8 posts)

If I can see the inner tube, can I still use the tire?Bruno S

In one of my tires there is a cut all the way through right in the middle where the rubber is the thickest. When the tire is inflated I can see the inner tube through a hole of about .050" in diameter. I took it out of the rim and I can see light through the cut. Should I retire this tire to the trainer wheel? Its my best (conti 3000) and newest tire (750 mi). Can I patch it like I would do a tube?

Patch it with a tire boot and use it on your trainer. I bought a tire boot at a sporting goods store. It is a large piece of self adhesive plastic that you cut to shape. A folded dollar bill also works.

The boot, a dollar bill, boot kit, piece of an old, mylar race number, keeps the inflated tube from pushing into the hole and bursting like a pinch flat. If you inflate the tire and fill the hole with shoe goo or some other heavy glue-like material you can prevent sand from getting into the hole and working it's way to the tube. I do this with complete faith, but my wife won't let me do it with her tires, so it's not for everybody.
Tyvek, not MylarKerry Irons

The white, non-woven "plastic paper" used for race numbers, FED-EX envelopes, and house wrap, is Tyvek, and makes a great tire boot. A double fold of a piece the size of a dollar bill will boot most tire cuts. Mylar is the plastic that recording tape is made of, and would not make a good tire boot.

Cost of replacement vs. cost of ambulance ride...cory

Seems like a no-brainer to me. I have pretty low standards for bike maintenance, but if you can see through to the air, I think the tire's a goner.

In a very short time it will fail catastrauphically - I've done it. Hit a small piece of metal in a paceline and within a mile my tire blew out. The tire is made up of woven threads that are near their design limit when everything is normal. Given that some are cut the surrounding threads need to carry the additional load - something they really aren't desinged for. There is considerable force involved and soon they too will fail. You need to either replace the tire or use something like a Park emergency patch. Given the cost and speed of replacing a tire vs. the skin you lose when you go down you should buy a new tire. Would you drive your car like this?
