Is it okay to store my slicks inflated (12psi) on their sides or is it best to let 'em down or inflate them more?

2 axle stands and a length of steel toob= no weight on the rubber

Put about 20lbs in them and stack them on their sides.

Reasons, Dave? The bloke I bought 'em off said the opposite They have tubes and are wrinkle wall. I like to have some science rather than a bloke told a bloke etc.

Latils method (well similer) is what we do with circuit slicks, standard pressures free standing on rims. another trick is to wrap the tyre (clingfilm etc) if not using them for a while to protect the compound and cover them to keep U.V. off them but that is maybe a tad over the top..

They don't wrinkle with 20lbs in them mate. Stored mine like that for many years. As far as I know the only thing you need to worry about is flat spotting them.

If you find out different let me know. Although it is a bit late for mine. I guess there is only one weekend at the Nats left in them.

Mind you. If I had the space (which I don't) i would probably use Latil's method.

Mine are kept in a basement, dry, concrete room with no lighting, so UV ain't a problem! Thanks for the input, fellas

Well lookie here!
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.)

Sounds pretty similer to our track tyre storage then, suprised they say to deflate them as Hoosier informed us to keep them up LOL mind different sidewall construction may be the key?

Why are my slicks directional?

Most slicks are directional, and ones that are not should be after the first time of use, look at pro race cars and you will see the arrows on the tyres

Actually. I have no idea what mine are inflated to. Because I gave them to Linda to store two years ago and I can't remember if i told her or not???
