Hey, I'm concerned about flat spotting my hooters if i keep them upright but was told that that's the right way to store them. Can someone tell me the right way

TIA

Ive been wrapping them in plastic, but I dont know if that really helps.
I have had a few sets on their sides and stacked and havent noticed any difference when they are mounted and thats after a year or two of storage.
be interesting to hear others' feedback.

I keep tires stacked unmounted but I was concerned about mounted tires.

Wrapping them in plastic will help keep the oils inside the compound, provided proper temperature and UV control is maintained during storage.

Usually a wall mounted tire rack is used to store them in an 'unloaded' state.
By setting them to a known pressure, you can also check for slow leaks during this time as well (a dilluted solution of SimpleGreen and water is often used for this.)

I do all three. I stack the mounted tires, but not stacked with air would not be an issue. without air, the rim weight might compress the rubber and possibly distort it overtime. I see this with the unmounted tires after a year on their sides, so I rotate them every few months.

Stack 'em. They'll be fine. Just put the stack in a part of your garage that does not get direct sun when you open the garage door IMO.

+1 UV damages the rubber.

I knew that protection from UV was important to prevent chemical breakdown, but temp also? What is "proper", prevention from cold? My garage heats up to the upper 90's in August, but I never considered that an issue (mine are mounted and stored upright on a wall mounted tire rack).

I like the way your avatar lines up nicely with your response to "stack 'em, they'll be fine."

I believe her best asset is more aligned with his "Professional Racing and Driving Coach"....

Hahaha... if you resize your browser window enough, you can get anything to line up there. "open the garage door", for example.

I just keep having the compunction to help her find what she's looking for....

I was also thinking about wrapping the tyres in plastic over the Summer. Are we talking Glad Wrap here? I think you guys call it Ceran Wrap?

Veloce Raptor

Every time ervtx does that, he ends up "resizing" his "browser", if you catch my drift here...

As for plastic wrap, I would avoid Saran Wrap. Instead, try heavy opaque plastic trash bags.

Just use them up.

If a tire is exposed to high temperatures (like being stored in a warehouse) for extended periods of time, then the tire can harden and 'dry out' as oils leave the compound. Obvious when you think of it, since it is rubber and not really designed for a heat cycle that lasts for months continuously!

At a national race in Florida earlier this year, the importer/supplier brought the tires to the event. Some (based on date codes) were almost 2 years old and stored in the top level of a warehouse, zero climate control.
They were almost 2 seconds/lap slower than 'fresh' tires (based on date codes). Absolutely repeatable, across all teams and chassis.
Needless to say it caused quite a stir in the paddock for the weekend.
(Just to make things interesting, the fronts were older/harder than the rears, so the grip/balance was way off to boot). Nice.

Kart tires are always delivered wrapped in clear plastic. When you remove the plastic, if it is 'brown' or hardened, then likely the tire wasn't stored properly and you might have degraded performance. The oils should be in the rubber, not on the plastic.
