    Bad day at the office! - 1st ride today

    I had my 1st ride today 6.3miles (there and back) but I got 2, YES 2 Punchtures (road bike) but heres my scenario

    I took the rim tape out of my rim (was bulging the tube) that was my 1st punchture, so that was fixed

    My 2nd one, new tube all done, about 25mins later it goes again, so heres my Q!!

    My tyre size is 700 x 28c but when the tube goes in its bigger than the rim for some reason, so should i get 700 x 28 or stick with the 28c

    Thanks

    What exactly is your question?

    If you have rim tape properly applied and using the right sized tube then it's probably pilot error. Either you're getting the tube caught between the tire and rim when you install and inflate. Or if using an iron your pinching the tube with that. Or when you pump the tire up you are doing it in a way that you are bending the valve stem in a way to to cause a leak at the stem/tire joint.

    Is it safe to assume your wheel is 700x23cc or 700x25cc? If so, the tubes you were using is too big. Go with 700x23 for both of those wheel size. If your wheel is 700x28cc, go with 700x25cc tubes. As locustfist mentioned, always use rim tape. You can pinpoint where the problem is by figuring out where on the tube is the puncture located at. If it's on the stem side, check the wheel to make sure there is no sharp debris in the wheel by running your finger over it. Be careful not to poke yourself if there is debris. If it puncture is on the opposite side, then most likely there is some debris on the inside of the tire or a something poke through the tire and tube.

    You can check your tube by inflating it and place it in a sink full of water to see where on the tube the bubbles are coming from.

    Go with 700x25cc tube and be careful not to inflate it until you check to make sure the tube is fully under the tire. I do this by running my finger all the way around the wheel on both side.

    Would 700 x 25cc not be too small?

    Not after you fully inflate it since it will expand.

    If you get a size smaller than your wheel, you will be fine.

    You never described your second puncture. There are several kinds, caused by different things. A recommendation on what to do requires a diagnosis first.

    What is all this "cc" stuff? We're not talking cubic centimeters here. 700C is a desgination, just like 650B. See Tire Sizing Systems

    And the OP said he had 28 mm tires and was worried that a 25 mm tube was not the right size. As he was advised REPEATEDLY of course the flexible rubber inner tube will easily expand 3 mm. Even a nominal 18 mm tube would work.

    If you have a good bike shop I think it would be a good idea for you to go there and make sure your wheel/rim strip/tire/tube are all set up properly. If they offer a class (many do) on basic maintenance, that would also be a good idea.

    +1, I was going to suggest getting a shop to put the tube in and then taking a class.

    You can also review some on line videos.

    #1 You're most likely not getting punctures. Punctures are from objects like nails, thorns, glass, etc. You're probably getting flats from lack of rim strip or pinch flats.
    Pinch flats can occur from running too low air pressure, then when you hit a bump...

    Or you get pinch flats when installing the tube. If not properly installed, the tube will be pinched between the rim and tire sidewall. Then when inflated it will cause a tear.

    #2 You can run tubes which are larger or smaller than your tire size. The problem with larger tubes, is they're harder to install without getting pinch flats.

    As Kerry pointed out, no problem to expand smaller tubes 3mm. Take a tube and connect it to your pump and start pumping. You'll quickly see it blow up like a balloon.

    So you took the rim tape out, put the tube in, pumped the tire up, and put the rim tape in your pocket just in case. When you had the first flat from a "punchture" you had no issues putting the rim tape back on the rim and getting everything together.
    BS - I'm not buying.
