I keep getting flat tires
I have a Trek 1000 road bike and I have had 4 flat tires in my last 10 rides. It's really annoying because I have in the past gone 6 months or more without a single flat. In each case I replaced the tube and tried to scan for anything sharp. 2 of the flats were in the front and 2 in the back. I'm riding on the same roads I always have. What are some other things that could be causing a sudden increase in flats besides bad luck?

Check your rim tape, or install new rim tape, and install new tires. Sometimes metal pieces get embedded in the carcass and you can't see them. Once you put 200lbs on bike the small shards poke out just enough to cut a tube.

I was having the same issue with my bike! I was replacing a tube almost every ride. Talk about expensive!! Damnpoor is right on the money. I replaced my tires first which didn't fix the problem. So I replaced the rim tape next. The rim tape I had on my bike was just a piece of rubber. I ordered Velox rim tape from JensonUSA and haven't had a single problem since. https://jensonusa.com/store/product/R...+Rim+Tape.aspx
It's $3 per wheel, which is a heck of a lot cheaper than $3 per ride.

LET'S ROLL
Next time you get a flat, match the hole on the tube with your tire.
Is the hole facing inside(holes from a spoke=rim tape or not enough air)
or is it facing out(glass, tack, etc.)?

Also remember, flats seem to always come all at once. I don't know why, but I to will go months between flats, then get several all in one week. I think that just seems to happen.

If you have many miles on your tires, they may be worn enough to allow a higher incidence of flats. I had a rash of flats on relatively new tires, so switched to more puncture-resistant tires. Continental Ultra Gatorskins and Specialized Armadillo's.

This is why you always "index" the tire so a particular part of the brand name is at the valve, and always have the brand on the same side. (Some say right side is "orthodox", I've always done left.) Makes it much easier to match blowout location with corresponding location on the tire or rim.

What nobody has mentioned is that in addition to knowing where on the tire/rim corresponds to the hole you need to look at the type of puncture. Each cause has it's own "signature."

thorn season
Not sure what you flats are from, but around here it is 'puncture vine' season.. Took four out of one tire today, and that is my 8th or 9th flat in the last 3 weeks. I ride a recumbent trike, and am switching to Marathon Plus as I've heard they are pretty puncture resistant.

And yes, look for the puncture, position, and shape, and let us know what you find.

Thanks for all the suggestions. I took the bike to the local bike shop today and it looks like it was something that should have been fairly obvious. Both tires were very worn out so it was easier for something to get through. I bought 2 Specialized Tri-Sport Flak Jacket tires and I am pretty sure that should solve the problem.
