Tire with a cut, what to do?(8 posts)

|I just bought a new set of Vredeatein Fortezza tires. On
the second ride I ran over some glass and flatted. After I
got home I inspected the tire over and have a good size
cut in the center of the tread. the cut is about 1/8 inch
long and is in the shape of an X. When the tire is pumped
at high pressure the cut opens a little, maybe like 1/32
or less. I,m a mountain biker thats recently started road
riding and was woundering if I need to worry about the cut.
I thought of putting a tire patch on the inside, maybe some superglue in the cut or nothing at all. I road yesterday
with no problems.

|I've had the same problem with my Fortezza TriComps. To fix it, I cut a small piece of an old tire (about an inch long) and inserted it inside where the cut is. That seems to be working but I can detect a slight "bump" where the patch is located. You might try this but grind down the old piece of tire a little thinner. I tried things like glue, duct tape, and patches, but they all failed.|

|Seriously, at 120 psi that thing is an accident looking for a place to happen. About the only thing you can do is to get one of the Park tire patch thingy. It's a bit of clear mylar type material with some super adhesive. However, it's meant to be temporary. If any of the chord is cut the surrounding fibers must carry the additional load. Eventually the tire casing rips open like a pair of too small pants....at the worst possible time.|

|I thought that was the whole advantage of the Vredestein tires is that small cuts would happen but the energy for the cut to go farther would stop continued growth of the cut and prevent blowouts. I was strongly considering buying some of these tires. You cast doubt. Anyone else have experience with Vredestein's.

|Glue and, where the cut is through the casing, some duct tape to kind of hold it together. They seem to hold, although I would not put a tire where the cut goes through the casing on the front under any circumstances.|

|If not, I'd boot it with Tyvek or something else that's thin and tough and put some shoe-goo in the cut.|

|I researched this topic over at google.com groups this winter. My Vredesteins were getting lots of cuts because of all the crap on the road, but I kept them going.
Deflate the tire. Glue the cut(s) Check the inside of the tire. If the casing has a ***minor*** tear patch it using the sticky part of a Fed Express Envelope (the one made of the flexible material.) Alot of guys have been using duct tape with good results. Reinflate. If there is no noticable bump in the tire the repair will probably last as long as the tire.
If there is a bump in the tire the casing is badly cut and the tube and tire may eventually fail.
Park Tire Boots are a great temporary fix, however they crack after a few hundred miles causing slow leaks from tiny holes in your tubes.
Do not attempt this type of repair on a sidewall.
