Losing air through bead

wooderson · 01-24-2012, 11:23 AM

My crappy local tire center can't get the bead to seal on one of my winter tires. They tried three times and it still loses air. Is there a trick to this? They are 235/35/19 Blizzaks and are a little stretched on the front rims.

Check for bent wheel, use more lube, use more air pressure, rotate the tire on the wheel. Hard to diagnose something like that remotely, but those are some of the common things to try.

Might also try putting that tire on the other wheel, and the other front tire on that wheel. That might give an idea if it is the wheel or the tire that is giving trouble.

had the same exact problem, i added some tire sealant, (the flat tire can/spray) about 5psi and seems to work well for now atleast.

Thanks. The summer Michelins held air fine and given the fact that they had problems getting both fronts to seal correctly, I'll assume (and pray) it's not a bent wheel. Guess I'll try a different shop and see what they can do.

Like was mentioned above, might be the wheel. Are you the original owner?

I am the second owner so it's definitely possible the wheel was bent and repaired. I really think it's the techs at my local shop (Mavis) who probably don't have enough experience with larger diameter wheels and low profile tires.

Why not just take a look at the wheel then and see? If it's leaking that badly, then the repair is probably quite noticeable.

Visually, with the tire mounted, I see no bends or indication of repair. The leak is slow. I need to add air every 10 days or so.

I put some bead sealer on the tire...it works for minor leaks most of the time. I had a tire that always leaked a bit...some POS Goodyear eagle F1 a/s tires.

Same thing happened on my gallardo. I had to take it to the dealer and have the wheel repaired, there was a slight bend on the inside of the wheel. Relatively cheap and quick.

cracked rim or a tear bead

i have same problem with my winter tires, the sizing may cause an issue. I also checked and I have no issues with my wheel. I had it resealed, and now I lose about 5 psi in 2.5 weeks.

I was told by the tire installer that it is most likely the bead because they can find no leaks when the tire is off the car and not under load. They used bead sealer twice so far with no luck. I'm going to have to take it to a tuner shop that I have used in the past for some of my other cars. They are used to mounting stretched tires.
