I took delivery of a set of 888's today. Unfortunately, the delivery company did not ring the doorbell upon delivery, so the tires sat on the porch for several hours.

It's minus 8C (15F) outside. I read a notice stuck to the tires cautioning about using and storing the tires below freezing, but it says nothing regarding my issue.

Is it a problem that they sat out in freezing conditions?

Thanks for your help.

My Yokohama AD07s are rated to be used and stored above 14f. 4 years in sometimes chilly Denver and no problems, even with a detached, unheated garage. I'd guess that despite the ambient air temp of 15f, your tires stayed a bit warmer, since it was daytime and they probably absorbed some uv rays (unless they were in the shade all day). Prolonged cold weather exposure-days of 10f weather while running them on cold or snow-packed roads, then I'd be worried, but a few hours on the porch wouldn't concern me too much.

Maybe the tire expert guys can chime in with something more definitive, though.

Thanks for the reply. They were under the overhang of the porch so they were not in the sun.

I could see (based upon the little I know about race compound motorcycle tires) that freezing might cause issues when heat cycled on the track (cold tearing). But, these tires will not see track time.

Am I off in my thinking?

Well, I'm not an expert, but I assume the tires are unmounted and thus uninflated...

Bring them indoors, or at least somewhere that's above freezing. I'm guessing that they will survive.

Back in January, I drove up to Willow Springs the night before a track day... temperature dropped to 23F overnight (and the tires, R888s, were pressurized and on the car), but there were no ill effects...

Im with ya on the concern.. When my 888s arrived it was sub freezing so I took them in side.

The ones on the car now have been sitting in sub freeze during this winter. No cracking or anything. I do know that the toyos have that consumer warning sticker on them.

Do the Yokos and other r compound tires have the same problem?

I was thinking about using them for a 2day track event. Just to get the last bit of use from them.

Has anyone had any issues doing this after storing them in sub freezing temps?

I will most likely just put the new ones on, but I hate throwing away such expensive tires. Especially when the fronts are only about half way through their life.

any comments?:shrug:

Yes, they are not mounted yet. I plan on slowly warming them up to >21C (70F) for several hours before they are actually mounted on a rim.
