Something to consider: On ATV'* a lot of people run Slime in their tires to stop leaks before they start. The slime is fiberous and works well. I believe you can use it in auto tires.

My first concern is getting the screw out so it doesn't damge the belts.
also I'm setting up a security camera although it seems to happen at least 2 months apart.

If the head is still on it, unscrew it. If not, get some vice-grips and unscrew it. Pulling screws out is a last resort (in my opinion)...

I usually unscrew it out then clean the hole out with a pistol drill.
The clean out round file type tool supplied is way too big.
You think maybe its better to just stick the plug in as is?
Good thing most of my driving is around town with short trips on the highway.

No, you gotta clean it some. Usualy the plug adhesive needs a clean, rough texture to ensure it bonds correctly...

You can, but it'* heavy, can cause tires to become out of balance somewhat, and will slow u down. When i went from slime tubes in my mountain bike to air ones, it was like night and day the difference in acceleration.

I would not recommend anything that stays in a liquid or semi liquid form in your tires. On one of my previous cars (when I was really poor) I used too much Fix a Flat on one of my tires. The part that stayed liquid caused the tire to be un-balance-able until the seal was broken and the extra crap poured out...

This thread jinxed me dammit!!! I ust got back from having new 400 bucks worth of new tires put on my car. Somehow ended up with a huge punture right at the corner of the tread and sidewall (unrepairable, dangit). So, I had to go with affordable stock replacements rather than the upgrade to 55'* that I wanted...

But I did get them siped!!!

Could they have damaged it while installing at the tire shop?
Seriously I feel I have a problem as I have a better change of getting struck by lightning than have two screws in two cars exactly dead center of the tire.

Me??? If you were asking me, I meant it to say I just got tire because of the puncture. The new tires only have maybe 5 miles on 'em so far....
