speed 6 tires problem

I have a speed 6 with only 6500 mile on it! I bought it brand new!
The problem I have is that recently took a look at my rear tires and they are worn really bad!!!
My front tires have more tread on them than my rear. My tires havent even been rotated yet!
I was wondering if anyone else has had this problem with their factory tires.
Also what brand are you currently using?
Going to have to get new ones soon.
 
Thanx T

yes there is a problem with them.If you call up mazda tell them your problem they well replace them .

Hey thanx man! I will def. give them a call! The factory tires are bridgestones. And i definatly dont like them.
Anyone else running a different brand of tire on thier Speed6 and had better wear on them?
