Yesterday I saw this huge bubble on the inside tire wall on my rear passenger tire.  Went to the dealer because I haven't ran anything over.  They sent me to the Firestone dealer.  The Firestone dealer told me I ran something over.  "see, here is the damage on the wheel to show it".  No you moron, that is dirt. 
Basically I have one tire that needs to be replaced and since I can't afford new tires, and don't want to pay over $150 for each damn RE92 I ask if anyone on here in the Bay Area happens to have a RE92 they want to sell.  I am going to Kirkwood on Saturday and don't want to go on the tire.

Thanks in advance if anyone can help out a fellow  owner.
