Sorry if this isn't exactly a Corvette question but it does relate to
tires. What is your thoughts on cars whose tires begin to crack on
the sidewalls due to age even when the tread is still pretty good?
One tire guy told me to prolong the life of the tire, use Armorall on
the sidewalls but I'm hesitant to do this because I recall in the 70's
that some were doing it to their dashboards and then they cracked and
others said the cracking was due to the Armorall. Hence I hesitate
to put this stuff on my sidewalls. Is there any stuff you use to
prolong the sidewalls from cracking or is this all a myth?
Also do you think at some point the cracking is dangerous to the
remaining life of the tire?
ps-- I chose this newsgroup over others because I think you guys are
real car enthusiasts compared to the other groups :) .
dont be silly , replace them!
under load, sidewalls are just as as important as the tread itself.
if these are original tyres then keep them for show otherwise
you are playing with ya life....
soap and water to clean only...

My opinion (assuming you need a speed rated
tire): ...any sidewall crack is reason to
discard the tire.
A crack exposes the casing cord to ozone,
moisture etc. (it's probably the 'etc.' that
will get you...LOL) Once it gets to the cord or
the steel components... sayonara speed rating!
Before you reach that point you'll probably feel
poor handling and hear more road noise -- as the
tread hardens. The tire may vibrate even if
it's well balanced.
I hate the recycling fee I have to pay on my
well-treaded turn-ins. I know they are headed
for some car in Baja.
All tire sidewalls will show cracking after prolonged exposure to sunlight.
Yes, I think cracking detracts from the life of the tire, but some say
any tire over
about 6 years old is risky, even if it's indoors on the shelf, because
continues to cure over time.
The Armor-All question is an ongoing argument, and I've yet to hear of
anyone running a scientific test, like treating just half the dashboard over
a period of years, or one tire on each side, etc. Those that buy it
repeatedly seem to like it and swear by it, others say it is harmful.
I take the safe route, I don't use it, but then I don't enter car
I never liked the extreme shine it imparts to vinyl, but they now do offer
a low-lustre version.
Here are some reviews I found with a Google search:
Teeny, tiny "micro-cracks" are normal aging.
Real cracks that expose anything inside the casing is a danger.
Yes, tires age whether or not you use them. Exposure to sunlight and
Ozone accelerate the process. Even if you drive the car only a few
miles each year, the tires should be replaced periodically. High
performance drivers will need to replace tires sooner than others. I
have discarded sets of tires that had tread left but had lost traction
due to age.
If you have your car detailed, the pros will certainly dress the
tires. I use various tire dressing products. I still get the teeny,
tiny surface cracks after a number of years. I've never had tires on
any car long enough for the cracks to get seriously big. I like tire
dressing for winter use because road grime won't adhere to the
sidewalls right after an application. Uh, no, not my Corvette tires.
They don't get to experience road salt.
Exposed core = end of tire life.
Tires are the only thing that connects your car to the road. Just how
much risk to your life are you willing to accept to get those extra
few thousand miles out of a set of tires?
Over 75% of Corvettes are sold with automatic transmissions.
