I got this zenna tires from carshoez.com and the tires have a tread pattern wrong. It does not for with the flow of rotation of the tire. The inside side tread is going backward and the outside tread is backward on two tires and forward on the other two tires. Tires sizes is 275/30/19 rear and 245/35/9 front.

I had purchased a new BMW with dunlop tires on. My tires are used less than 1 year and used only for 34,000 km (21,200 miles) but there are no threads left on the tires. I have contacted dunlops customer service in America and contacted their office in turkey and they have sent an expert to check the tires. They claim that the air pressure was low so the tires were worn quickly. That is ridiculous because my car is new and it was checked by authorized BMW service for routine checks several times and I have a report from authorized BMW service that tire pressure was normal. On the other hand this car has tire pressure sensors and there were never low pressure warning. I have made a research on the web and found out that dunlop tires had so many customer complaints similar to mine and high court judge found dunlop guilty for 300 incidents involving a faulty brand of tire, which caused at least one fatal motorway smash. On the other hand a biker died due to faulty dunlop tire and another injured seriously. (the suit (cause no. Dv-08- 480) was filed Nov. 10, 2008, in the second judicial district court, butte silver-bow county.). do I have to go to a court or get killed to have my tires replaced? a copy of the above was sent to (federal trade commission bureau of consumer protection).

I need the following us tire retails to be inspected, analyzed, tested and/or whatever governmental procedures need to be taken in order to find out, fine, correct, determine whether or not the tires stocked, manufactured are within federal guidelines requirements for safety and all other technological safety aspects. Please inspect all Goodyear, ntb, discount tire, and Firestone shops for their stock of known tire defects.
