Tires: cracking in tire tread, firestone tires, saturn ion

Question
I am buying P 195/60 r 15 Firestone tires on a 03 Saturn ion.  (21,000 miles) It has been driven less than 100 miles in the last year. Stored on concrete garage. One small crack runs
around the tire in more than one groove.There is lots of tread left, Can I drive these tires a 100 miles a day?  

Answer
Charles,

I'm not sure I understand the question.

If you are asking if the cracks mean the tire should be replaced - well, without looking at the tires, it is almost impossible to make a judgement.  From what you told, it doesn't sound good, but it is hard to be sure.  You should have someone at a tire shop look at them.

But if you are asking if there is enough life left in the tires to drive 100 miles in one day - enough to get the vehicle home - well, this is an odd question and I'm not sure I can answer it, especially without looking at the crack.  Nevertheless, it just makes sense for someone at a tire shop to put an eyeball on them.
