wal-mart wal-mart douglas tires kokomo Indiana

 I bought tires for my 85 year old grandmother. 185/65r14 douglas x-tracII.  I do not have the exact mileadge but she does in town driving to the grocery and church once a week.  I dont think it is possible for her to drive more than 5000 miles a year.  There are no problems with the tires of any kind except they are soft.  It has been 8 months and the tires need to be replaced. My shop is next door to her house so it is easy to keep her car well maintained. Air pres. ect..  We are a racing family but grams dont drive over 40-45 miles per hour.  Unless she is racing her little saturn on fri night or doing emergency brake 180's behind my back I have to say the tires are FLAT OUT JUNK.  I dont expect a tire to actually reach the 45K mileadge but if it wont make it more than 8-9 months with a little old lady driving it to church.  What would you say?  About one month after the tires were installed she was out of town and she run over something. Tire barn installed one new tire with a 50k tread wear rating. I can not measure even ONE mm of wear on that tire. The three walmart tires have only two mm or less tread left. One tire doesn't have enough tread to measure. If there is a class action lawsuit please let me know.
