How to Treat Dry Rot in Tires

I have a 1990 Toyota pickup. I've discovered some minor cracking on the side walls of the tires from outside storage in the Texas heat. What is the best over the counter product to apply to the tires to slow down the deterioration process?

I have never heard there a product to fix them or sow dowm the process. I always thought you were suppose to toss them for some new ones.

Ok. Thanks for the info. I guess it's not like dry leather where you can try to re-condition/treat them. It's just a utility truck for driving in the country and camping. I'll probably try to keep the tires as long as I can unless I see major cracks develop. I hate to replace them since the treads are new and they were replaced 2-3 years ago...

Dry rot on tires means that the tires are toast. You need new tires as there is no product that can fix or delay the progression.

You're running on maypops right now.

Here's some info from ehow.com

"Dry Rot" vs. Sidewall Cracking
# The term "dry rot" applies only to old cotton-based bias-ply tires that haven't seen production for the street in 30 years. The condition as it applies to modern tires is called "sidewall cracking."
Pressure Loss
# There's about a 50/50 chance your cracking tires will begin to lose air pressure in a slow leak before catastrophic failure occurs.
Pressure Failure
# These small cracks can open rapidly, releasing the tire's air pressure in a severe blow-out with no warning whatsoever.
Splitting
# Sidewall cracks can lead to sudden and massive rips in the sidewall severe enough to separate the tire from the rim.
Failure Scenario
# Since a sidewall's job is to absorb road variations, sudden failures will usually occur while traveling at high speed on imperfect roads.

ceb added comment: While water based lubricants can slow the development of dry rot by keeping a tire from losing the additives that are part of the tire when manufactured, once dry rot sets in you can't "fix" it by using 303 (a product I thoroughly love.) All you can really do is replace the tires.
