If stored uninflated, they are probably safe, but won't be fast. Give them
a thorough inspection and monitor their condition frequently. If they are
built with nylon cap plies, they will thump for a period before they let go.

And what if they were stored on the rims and inflated. But not fully
inflated. Also several people have recommended Formula V if the tires
weren't cracked. Does it actually work or is it snake oil?

OK, what's the role of inflation for stored tires? When I change for
the season, I just put the removed tires on a shelf in a shed, usually
on their side, but maybe one standing up.
Is it important to deflate or overinflate? Why?
TIA

A good soaking with Formula V will bring most of the traction back.

What's in Formula V anyway? I think Gary D. suggested at some point that it
was just bleach, or else that bleach works as well as Formula V. Any ideas
anyone?

The one thing a TPMS can do is catch a puncture while you're driving. That
is a good thing as it may save a tire. I've driven my M5 on a flat and
ruined a tire.
They are more valuable for clueless consumers driving high profile vehicles
where it can save lives, but do provide a benefit for everyone.

I have not found the Greestuff's to dust bad at all....especially when I
tossed them in the trash ;-) Cant stand those pads. Terrible on the E30. I
went from the Greestuff's to Akebono ceramics and really like the Akebono's.
Great street pads.

Do you think the Akebono pads would be OK for the occasional autocross?

Yep....what Gary said ;-)
While I very much hesitate to use plugs on my BMW's tires I dont hesitate to
plug the tires on our LR Disco that sees quite a bit of off-roading. It used
to be that I would not plug them but after replacing an expensive tire to
just rip it on a rock a few weeks later I am all for the plug ;-)
The one thing I will add to Gary's comments is that if you are going to plug
them, use a good quality kit, I like the 'Safety Seal' kits:

A primary reason to not use a plug is to dismount the tire to inspect the
inside. A long nail can rub another part of the tire.

If you drive at 10/10, you have no reserve to avoid the bonehead, and you
will be going faster when you hit him. If the tires are wooden and only
give 7, then driving at 7/7 also allows no margin. But driving at 6/7 does.
It depends on if you are racing for a big wad of fame and fortune, or
running a driver's school for fun.

To add to what Brett posted, there are light green base bulbs also. These
do not replace the black base bulbs and will likewise burn out quickly.
This is from direct experience.
