I'm now convinced my wife's bike is a flat magnet, she rides 1/10 the mileage that i do but she gets more flats in month than I do in year.

What kind of flats? Have you been able to discern what's causing the flats?

This last one was a tack, before that a wire no pinch flats so far just put in new tube and slime flat protector tire is only 6 months old.

Münchausen syndrome a la bicyclete? lol

What are you guys riding? I commuted on an MTB with slicks for a while, and concluded that all things being equal:

wider tires = more flats

Flats are Luck...Good or Bad

I agree. I used to commute on a folding bike (great for the Metro!) but it had 16" x 1.75 tires and flatted (on average) once per ten commutes. Since the Metro installed "bike cars" I now ride my road bike (700 x 23 tires) and have had exactly one flat in over 50 commutes (the one day it rained, of course).

Put skinny tires on your wife's bike: Problem Solved!

Correction it was 3/4 inch nail with a tack like head, she's running 24X1 skinny tires it's a Terry type bike Centurion Ironman Expert.

If she's rolling over tacks and nails, maybe there is more than bad luck involved. How's her vision? Is she even looking at what she is riding over, or is she just going along as though she has steel-belted car tires? How about her lane position? Is she riding in the debris-zone near the gutter? Does she have adequate bike handling skills to avoid the hazards she does see? Oh, do you two ride together? The rear rider doesn't have much chance to see the debris and avoid it. All of these things can attract flats.

Then again, maybe she's just unlucky.

Don't know why you are worrying. It's only flat at the bottom- the rest of the tyre is fine.

Good points B. Carfree the more i think about it she does tend to ride closer to the curb than i do mostly because she's not confident around cars like she used to be 20+ years when we were riding all the time and her vision is something she has been complaining about.

Tell her not to ride that close to the curb where all the debris/detritus gathers.
We use Maxxis Re-Fuse 700x25 folding tires and had 2 flats in 5,400 miles.
Yes, we have lots of road debris and loads of cactus thorns!

Stop Flats 2 liner -> no flats in many thousands of miles of San Jose streets.

For those of us using 23X700's or 25X700's with 100 pounds of pressure or more, we can minimize flats by deflating tires after each rides, overtime those high pressures weaken the fabrics and can be punctured more easily--besides a little warm up before each ride is beneficial as we pump up those tires!
