You guys ever figure out anything besides keep adding air? This is a slow leak, takes several days, maybe a week to go flat.

I read your other thread and know lots of people who run Hoosiers (some stuffed quite a bit for SCCA stock classes) and have never heard of this problem. Next time I get new Hoosiers (ordering next week actually) I'll ask my tire shop what they use to seal the bead.

I once had a set of hoosier R6 and one tire went flat over night. There was nothing wrong with the tire in terms of major leak. Just made sure it was full before going out and it worked.

Probably just gunk on the wheel where the bead seats.

I have heard of tire installers tearing/damaging the bead/seat that had issues like that. Might want to let all the air out and check....

Thanks all, my tire guys are good, I'm on a first name basis with the two "senior" guys & they take care of me. Despite his best efforts (he tried bead sealer & tried thorough cleaning of bead & rim), he still has a tiny leak.

I got reports that this is a known problem, that you more/less live with on some Hoosier tires.

Something about excess rubber flashing on the bead.

Does not make a lot of sense to me.

I've probably gone thru 100 a6's over the years & this is the first with a slow leak.

He was giving it one more try on Sat night as I was going out & will pick up Monday.

I told him to use one of those green plastic scrubber things on the bead, lightly to clean & rough it up a tiny bit.

We'll see.

It's not a street tire so if I have to air it up once an event it's no biggie.



This technology has been around since the late 1880's.

One would think the manufacturers had it figured out by now.

I thought the air leaking out of the Hoosiers was a built-in feature! It compensates for the pressure buildup during a run session

whatcop?

I have the same issue with one of my hoosiers. Couldn't figure out why.
