|Do tubular tires need to be re-glued after one year?||yzfrr11|

|I have a set of zip 303's that I save for race. I took them out last weekend for my first of the year but it seems like the glue has dried out a bit and I am considering re-glueing them. The glue is about one year old.
Is it nessesary to reglue tires after a year?

|I've used two tests to see if tires are glued on well. The first is to put about 15 psi in the tires and give them a firm tug. If they start to come off the rim, you need to reglue. The second is to inflate to normal pressure and try to roll the tire off the rim with all your strength.
If in doubt, reglue. I had a back tire roll off the rim on a high speed corner. New rim, new spokes, new skin. I've been riding clinchers ever since.

|Use your thumbs to try to push the tire off the rim with 40 pounds of air in it. If you can't, the glue it still good.|

|If you used one of those gutta glues (white stuff, like Tubasti), it probably is good for a few years, although it will never really be great. Gutta glues stay very pliable.
Clear(ish) glues like Vittoria Mastik1, continental, Wobler, etc., are probably OK for a couple of years before they become brittle.
If you are one of those who uses FasTak, that stuff dries out very, very quickly. A couple of months and it gets brittle. Dried-out FasTak has probably been responsible for more early season roll-offs than any other glue. Don't use FasTak for anything other than an emergency "quick" glue.

|I don't buy the fastak comment. i have fastak on my track tubulars and they're still good after 3 years (check them before every race day). Also, it seems thats just about the only thing the people i've talked to use at my velodrome and i haven't seen a rolled tubular in 3-4 years. of course i'm sure people use other glue, but i know many who use fastak and never had a problem. it is made to attach car molding, so its designed to hold tough through all weather and temperatures.
maybe it holds better due to higher pressures in track tires?
I think that as long as you are thorough in mounting the tires, you'll be ok as long as the tires pass the aformentioned tests in previous posts.
