What is with these tires?

[Ferris Leets]

I will recap my experiences.
Had the Valk for a few weeks and picked up a LONG deck screw in the rear tire.  Pulled and plugged.
Discovered I had a slow leak.  Found it and tried everything to fix it.  On the rim near the valve.  Weeks later realized thqt the deck screw had pierced the bead right at the edge of the rim. 
I had to put air in every day but did not really want to get rid of a nearly new Avon.
Two weeks ago while airing the tire I saw Slime bubbling out near my slow leak.  Found a tiny brad, like you use for putting picture frames together.  Between the tread and just long enough to get to the air.
Pulled it and figured the slime would stop the tiny leak, nope.
New tire time, got the Falkien 205/75-16. 
Pulled the rim off and used a sawzall to cut a big hole in the tire to wash the slime out.  Those tires are tough to cut.  Took the tire in and had it mounted.
Checked the air, good.  Next morning no good.  You would not have wanted to be around for the next 5 minutes.
Fortunately I figure out that it was the schraeder valve.  From being in and out, dropped on the floor, etc etc. it was leaking.  Also fortunate I have spare new ones.  Installed that. 
That was 2 days ago.  I am going to check tonight and see if it is actually fixed now.
In the mean time I have pulled 3 self tapping screws out of my truck tires.  At least they were too short to get to the air.

Have you got someone laying nails out for you / Where do you ride, Construction sites ? Hope you got it taken care of. Dave

Replace the whole valve stem.  The originals are junk.  Get the ones that use rubber washers and nuts on the inside.  You can install them without dismounting the tire, just break the bead and clamp the tire back while installing.  One source is patchboy.com. I just installed one on the rear of one of my valks and got three more for future tire changes.

I had something similar happen recently, picking up several punctures within a few days on my valk and wife's car. I walked down our street looking at the road and found a builder had swept out his truck into the kerb leaving loads of screws, nails etc around. I picked up over 40 screws from the road which I suppose might have saved me 40 more punctures!

Some folks have found that if you install a front fender skirt, it reduces the rear flats. The skirt blows away small debris in the road, including small nails and screws.

Pnuematic tires will always leak air if punctured or if the valve stems are comprimized.

Replace your tires with solid rubber tires and ride virtually forever.
