Hoosier front runners...
 

Any "history" of them splitting/cracking all the way around the sidewall? (Mine have one season on them and are 28.0/4.5-15 I run 40 psi in them)

Re: Hoosier front runners...
 

I have the same tire. Run 40 psi also on 4400 lb car. No problems in 3 seasons.

Re: Hoosier front runners...
 

Same tire, 35 psi, no issues after several years of use.

Re: Hoosier front runners...
 

I've used that same tire for close to 10 years, never had a problem. Hopefully, it was just a defective tire.

Re: Hoosier front runners...
 

I have also used that tire without any problems ... Were they new &
did they sit outside ???

Re: Hoosier front runners...
 

Keep them away from ozone sources such as electric motors.

Re: Hoosier front runners...
 

It depends also upon how to store them for the winter. I was told by Hoosier, both front and rear tires should be removed from the car, deflated, and stored in a cool dry place out of the path of any sunlight.

Re: Hoosier front runners...
 

Mine are stored on the car, full of air, off the ground, in a un-heated, attached garage.... very little, indirect sun light... Yes they were purchased new....

Re: Hoosier front runners...
 

Where did you buy them from?

Re: Hoosier front runners...
 

I read, iirc on Hooiser's website, that tires should be stored with 5 psi and not allowed to freeze. While I don't reduce air pressure, I keep the garage temperature above freezing.

My local speed shop....

Re: Hoosier front runners...
 

I wonder if that's the lawyer's talking, or if it's actually critical. I would think that there are plenty of them that are below freezing right now, and have been before.

fwiw, here is the text on the Hoosier website:

12. What are the do's and don'ts when storing Hoosier race tires at the end of the racing season?

TIRE STORAGE
The useful life of a tire, whether mounted or dismounted, is directly affected by storage conditions. Tires should always be stored indoors in a dark, cool, dry room.

DO

1 Remove the tires from the vehicle.
2. Remove the air from the tires and store them on their side in a cool/dark/dry environment.
3. Place tires in a black plastic bag when stored during the "off-season".
4. Make sure the temperature range in the storage location is between 40-90 degrees Fahrenheit.

DON'T

1. Don't store tires in direct sunlight or near electric motors. (Electric motors emit small amounts of ozone.) Tires need to be protected from light, especially sunlight. Light causes ultraviolet damage by breaking down the rubber compounds. The storeroom should not contain electrical welding or any other equipment that could produce ozone.

2. Don't apply any chemical treatments to Hoosier tires. (It's not necessary and may actually damage the integrity of the tire by breaking down the rubber properties of the tire.) Tires must not be allowed to come in contact with oils, greases, solvents, or other petroleum products that cause rubber to soften or deteriorate.

3. Don't store tires in sub-freezing temperatures for any length of time. (The rubber can freeze and may crack as a result.)

My first set came cracked around the side walls from the distributer. I had them on the car until we finally got it to launch like a fighter jet. the second set has been on for 2 seasons and still no cracks.

Every one I have ever had has cracked, but it has never been an issue yet.

Re: Hoosier front runners...
 

The more I look at fellow racers Hoosier front runners, the more I think this is true....... :-(
