Title pretty much sums it up. My right front tire has a slow leak - slow meaning that about once/twice a week I need to put air in it. I have seen the spray in sealants but do they really work?

Do you know where the leak is from?

I'd have it fixed. A slow leak could be anything from a nail in the tread (repairable) to a bad tire mount (repairable) to a damaged sidewall (irreparable). It could lead to sudden deflation though which is obviously not good.

Just go to your tire shop and have them look it over and fix it. Safest and best way to to it.

We had a tire like that a few years back, and used the Fix-a-Flat stuff. Managed to get us all the way across the country (OH to FL) and back before it started losing pressure again. I don't think it's rated for a trip like that, it may have been a fluke.

But it should at least hold long enough for you to get the tire fixed.

Fix a flat is bad for the tire, rim and repair shop that has to remove the tire when you finally get it fixed.

Take it to a shop, they should be able to find the leak and advise you on the correct path for repair.

Could be a leaky valve, too. You can spray a little soap and water mix on it and see.

Windex works great for this too.

^ spit works.

The Fix a Flat is only meant for emergencies. It's flammable which is why you need to tell the mechanics if you've used it so they can cycle air through the tire and not have it blow up when they trying to unmount it from the rim.

Take it to a tire shop and have it repaired. It'll cost you about $10 assuming you don't have a bolt through the sidewall or something.

Could you pull out a valve and put it in yourself?? I never did it before. The valve core could be lose. You can get a valve core tightener. When I had the same problem I took the entire tire off my car and stuck in it the bath tub. I put a towell on the bottom so I don't damage anything. But You can easily see when it's leaking. Because it could be leaking from the steel/alloy rim as well.

Put a new valve core in it?

I have a little bottle with new valves cores stored in it. The cap of the bottle has a built in tool to let you unscrew a tire valve core and replace it yourself.

In any event, he would know what the problem is so he can go to the shop informed.

Point is, if he knew how to replace the Schrader valve, he wouldn't be on here asking what to do.

Oh? I knew repair shops hated the stuff because it's flammable and gums up the inside, but how is it bad for the tire and the rim?

Well, one of us enterprising folks could have instructed him if he reported a leaky valve. :D

Also, he would know what the problem was when the shop tried to sell him a new tire or a new rim instead of a 38 cent schrader valve. :D

It isn't harmful to the rim, but it does get stuck to it and is hard to get off.

It ruins the tire and it can be harmful to the rim because it can get stuck on it. It SHOULDN'T ruin a rim but would you want to chisel all that crap off after changing a tire?

How does it ruin the tire exactly?

Bad tire mount as suggested above could be possible particulary if the rim is old and suffering from a bit of corrosion. had this problem myself on a tire. Wire brushed the inside if the rim an it fixed OK.

Many brands of tire sealant today still contain butane, propane or isobutane as the propellant, which are all flammable and highly explosive.

It eats and softens the rubber which causes excess fatigue. There are many stories about failures if you care to take a quick peek on google.

I see plenty of links about explosions. I even see a link to a sermon based on Fix-A-Flat (quick solutions vs. enduring solutions). I see no links about it "eating" the rubber. I searched for "fix flat tire failure" "'fix a flat' failure", and "'fix a flat' tire failure". Got a link?

The flammable ones should be long gone off the market by now, iirc.

The problem now is that your tire is full of goop that the tire guy has to deal with.

If you are stuck and you gotta use it, then you gotta use it...

Don't get stuck. Keep your spare in shape and know how to change a tire. :D
