Tires Cracking....
 

I noticed the other day, that my wifes tires are starting to crack on the outside lugs of all 4 tires. They are th e 20" Bridgestone's with 36xxx miles and they are only 2 years old, what gives? I thought B'stones were better than this?!!:mad:

Did you use Armor All on the regularly. If so that is why. Tire shines that a high in silicone react with exhaust gases causing the tires to crack.

Not Armour-All, but did use "Tire Foam" stuff....guess it aint no different, huh? So, should I not put anything on the tires?

I have bridgestones on my truck, already lost 1 to dryrot, had I not been so excited to buy the truck last year I would have had the dealer put on new tires on, the other 3 are cracking horribly.

Anything that has a high silicone content. The more the silicone the more cracks. I use Jet Wet and have not had a issue.

look to see when the tires were made

Here is an example of what to looke for

DOT U2LL LMLR 5107 Manufactured during 2007

I have known for years how to read the dot stamp...thanks...these tires are '08 vintage....that it why I'm concerned, as for the silicone content, my "Hankooks" on the 'burb don't crack, and they are '06....:confused:
