Folks, I'm relatively new here and haven't seen statistics on a problem that plagues me but doesn't seem to occur too often with my biking buds: flats.
I thought it'd be useful to poll you all and assess the overall experience of this NG with respect to: flats.
Please chime in with your stories regarding: flats.
Me? For years I've been plagued with flats on various bikes, through various tires/tubes/rims, have almost without exception used "tuffies" or the like. Without exception, however, my tires are at the PSI limit. And I suffer the occasional "mystery flat", where the tire flattens but somehow magically holds a "charge" after the original flat.
I weigh 220 lbs. Might this have something to do with it?
I consider myself to be a 4 FPTM kind of guy.
:cry:

Ohhh, Bad Karma. Never talk about how many rides it has been since your last flat. That's just begging for double snake bites....

It's been 8000 miles since I had a flat. I credit it all to my superior bike-handling ability and supernatural visual acuity.
:D

Here's a stat for ya then...I've logged something like 25,000+ miles on three different bikes over a period of 6 years, and all three were MTBs. In that time frame I've only had 5 flats, and of those five only ONE was on the road. The other four were the kind where you stroll out to the garage and your trusty steed for a spin and discover it has developed a gimpy hoof overnight. Those seem like pretty incredible odds to me, but then I have always used thorn-resist tubes so maybe that's payed off...

Over 2000 miles, no flats so far, but I do use puncture resistant (not kevlar) tyres and slime tubes...

I usually go for quite a while without a flat but I've had a couple of flats in the last couple of days.
They are annoying flats that cause a slow leak. In each case - one very small hole. Seems to come from the tyre, not the rim, but I can't find any tiny piece of glass or anything. (Believe me - I've tried.)
Oh well. I'll see if it all stays together tomorrow.
Last summer on 5 bikes (so therefore ten tyres) we clocked up about 700 miles per bike, or 700 miles per tyre, so in a total of about 7,000 tyre miles - 1 puncture.
All were 26" road tyres with tread, nothing special or expensive

for me it depends on the bike, the tires and the type of riding...
on my commuter which is a MTB with wide semi-slicks with about 50psi and tuffys i get about 1 flat per year or 1 flat for every 3000+ miles or <.3flats/thousand miles
for off-road i get a lot more with 2"+ tires between 35 and 45psi, probably about one every month or so roughly 1 flat every 250 miles = 4 flats/thousand miles. some of these are snake-bites if i don't run enough pressure, but most are just the usual thorns, glass or sharp things. but i find the frequency acceptable.
on my racing road-bike, i get way more flats than what i feel like i should... probably somethine like 1 flat every 400 miles or 2.5 flats/thousand. i run about 100-110psi... i guess some of it could be that i spend more time on my mountain bikes and i don't avoid some obstacles that maybe i should with the skinny high-pressure tires on the road bike.

I had flats, five in two hundred miles, because the inner tubes I was buying kept losing the top of the presta valves. I have started using Specialized brand inner tubes and so far so good for over two hundred miles.
Pesky Arizona thorns have gotten me twice in 750 miles.

on a ride If I have a flat, that would end up having multiple flats, I really don't know but they would usually comes in quadrupple flats
So far this year: One flat in 3500k.
Last year: Two flats in 5400k.
So, is 0.5FPTM "basically, none" or "way too many"? :)
