Dry rott on tires a serious problem?

[Graham_A_M]

Hey guys. I have a set of Toyo all seasons on my winter car, and I noticed some dry rot is beginning to occur; whereas the sidewalls are devolping little spider cracks all over the mid section...

what caused this? since their not too old, perhaps two years.... and they dont have a history of underinflation.
this happened after the car sat from June to Oct this year it seems....

as well as, since their quite minor, perhaps a few MM thick, is this a problem? and if so, how do I fix it or stop it from spreading...

Thanks well in advance.
-Cheers and happy new year:thumbsup:

Bring it by the shop and I can have a look at i and give you a more educated opinion... Nomally if the are starting to crack just a wee bit, normal driving around town is not too much of a worry at all, but they are pretty deep, I would not be overly comfortable blasting up the deerfoot at 140kmh...

cars at my work develop salt deposits all the time and they cause tires leaks like mad, just dismount and clean the rim with emery paper or if your really crazy a dremel tool with the green rubber fitting
