I've run Hoosiers slicks for about the last 15 years and never had a slow leak thru the side wall problem. Not like some others of days far gone bye.

I think everyone would agree that Phoenix bias plys (particularly when they were Firehawk or Firestone) were the worst for air loss over time. That's pretty much where the whole "dish soaping the inside of the tire" thing got started. I currently have a set each of Phoenix bias plys and radials and can tell you from first-hand experience that neither version leaks at all. Phoenix/Firehawk/Firestone bias plys were the tire of choice among Super Stock racers for years, but the constant air loss made them a huge pain live with.

Forgot one thing... conventional wisdom says that Hoosiers are the most susceptible to radial wobble, Goodyears are next and Phoenix are the least. If you're lucky enough not to experience the condition, you'll never know what it is, but if you do, you may get to the point of changing tire brands to eliminate it. Watch video of some of the Hemi cars at 1000 feet and you'll see exactly what radial wobble is.

Must be something that happens on the wider radials. I've been running 9" radials for over 20 years, mostly Hoosier but some Goodyear, and I don't know what you are referring to.

I haven't heard much about it on Stocker radials, but I don't race a Stocker. On Super Stock radials, it is hit-or-miss (some cars experience it, some don't). It shows up as a side-to-side rocking motion. If it gets really bad, it will look like the rocker panels are going to throw sparks. Been discussed here a few times, lots of theories on what causes it and what will eliminate it.

I've been running radial slicks longer than most everyone posting on the net as well I have logged far more runs than anyone on them.

That said, I've been running Hoosier 32/13.5 radials since 2008, racing every weekend from April through October without radial wobble except one time at one track and the cause was the track.

My car was killer at this track/at this race and IIRC, I ran five, 5.60s in a row, won the boggie race too.

Then once the sun went down and the track cooled, it was a different car and I had radial wobble every pass and had this not been an 1/8th mile race, I would have had to lift.

Point being it was the track not my car.

Left that track, made no changes and the car was right back to perfect launches, passes where ever I raced it.

BTW, that was the last time my car has had radial wobble and that was 8 years ago this November. Radial wobble has nothing to due brand name or air pressure and everything to due with track prep and chassis setup.

Oh and I run 21 psi my 32/13.5 radials.

I run Hoosier radials on my car. I do get the wobble at times. Certain tracks seem to be more proned to it. It seems to be worse on my car as the tire pressure is increased and it also seemed worse with lighter springs on the back of the car. I typically run between 12 and 14 lbs. in the rear tires depending on the track conditions. I run the 13.5/ 31.5 tire. Definitely no issues with traction and repeatability with that tire

On a bracket car? Why?

because I can and because my MPR built former GT/AA Super stock car, run as a bracket since 2008 is quicker and faster than most Super Stock cars.
