Father and son first ride . . . . . . first flat.

My father has been riding for a while now and encouraged me to join him. So I found a Schwinn Sprint for cheap and picked it up, a few odds and ends and got on the road. We are both bigger guys aiming to loose some weight and have some fun. (250 - 270)

Out first ride out started great and then about halfway into our 8 mile ride I got a flat. No big deal, we just pulled off to the side, took the wheel off, pulled the tire, patched the tube and got back on the road.

A few days later I decided to head out on my own I got about halfway through my 7 mile ride when I heard a huge pop and saw my tire off the rim. I pulled over and started getting to work . . . . I knew the tube was toast but I had to know for sure before I called for help. Sure enough the tube had a huge rip down a seam near the valve stem.

We ride mostly on smooth surfaces but occasionally get out on some country roads and run into some rough patches. I have decided to swap out the smooth tires on the bike for something with more of a commuter tread. I have read that the wheels on this bike don't have a lip to hold the bead of the tire so I shouldn't put an excessive amount of air in them or they will pop off the rim. Is this going to be an issue for me? Are these wheels strong enough for such a big guy?

Thoughts, comments, concerns, all appreciated. I just want to get out on the road and not be so worried about having a flat or a blow out.

27X1 1/4 on that bike, if I recall. Best choice of that size is probably the Panasonic pasella tourguard, or Schwalbe Marathon Green Guard.

But your second flat was almost certainly improper installation of the tube. If you can hear the pop, it means that the inner tube was outside of the tire. Usual cause is pinching it putting the tire on, and getting a bit of tube under the tire bead. f

Yeah that is the correct size. I looked into that after I had that issue and I believe that may have been the issue. I have never installed bicycle tires before and I'm sure I screwed it up a bit. Live and learn I guess.

May be a silly question but if you recently picked up the bike used....you have no real idea of the condition of the tube...maybe just a new tube and a really good inside and out tire inspection.

Read Sheldon's page on flats:

It might be a good idea to practice a couple times, at home, when you're not pressed for time, and can figure out if you have all the tools you need.

I purchased a vintage road bike a few weeks ago and experienced my first two flats within 3 days of each other. I weigh in at 230lbs and my wheels are also 27x1 1/4"

I purchased new tires and tubes and now I always make sure my tire pressure is maxed, and of course you must watch the road for ugly bumps.

Haven't had a flat since.

I did perform a inside and out tire inspection when we got home from the first ride. I decided to replace the tubes just to be safe. Is the issue with no lip on the rim a real concern or just a "this could happen" kind of thing?
