    my tire is too big

    I bought new Gigantex carbon rims for my road bike. The tires are about 2 months old and the front one keeps slipping out of the rim. Is there someone with a lot of experience with tires that knows which tires have a tight fit? There is a thread that explains that Michelin tires are tight fitting but that thread was 6 years old. They might be different now.

    This forum has different sections that are set up by the owners for different types of subject matter. There is a 'wheels/tires' section for questions like yours. In the future please use the correct section.

    As for your question, it's not a problem w/ the tire or them, or it shouldn't be. More likely a problem w/ how the tire is being installed.

    I'm assuming identical rims and the same tire in the back and the back combo is okay. Don't be afraid to actually apply some thought here.

    What does that mean, slipping out of the rim? While you're riding? While you're installing?

    Have you tried other tires?
    Have you tried swapping the front and rear tire?

    Installation goes good, then about 1 hour into the ride the front tire slips out a little, I feel a bumpy ride. The inner tube does not blow out. I lower the pressure, push the tire back in, and pump up to 80 psi, and finish the ride.

    My first thought would be a defective bead on your tire.

    What is the INTERNAL width of your rims? Which rims are these?

    I would change that tire out immediately after finishing the ride, are you crazy?

    I get the feeling that this particular Gigantex rim is defective, either its diameter is a little small or its bead hook is weird. It would be helpful if you could compare the diameter of the front vs the rear Gigantex rim. Take a piece of sewing thread/string and stretch it across the diameter of both rims and see if their diameter are the same.

    The obvious thing to do is switch the front and rear tires. Then you'll know if it's a problem with the tire or rim.

    Your next decision is completely uninformed until you try this, and any other input is useless.

    Either your rim is defective or your tyre is defective. One or the two, or perhaps even both. You might have noticed that the rims aren't the same width, or your tyre is defective. It should be one of the two and you should be able to work it out. If the tyre is defective take it back and get a new one. If the rim is defective either get it replaced or buy a new one.

    Such lame advice that is utterly useless.

    And do you have any good advice to add? As usual, no. You're just trolling with insults and cornball jokes that nobody thinks are funny.
