Just wondering if its typical to go through rear tires as often as it seems. I own a 2004 since new and have had basically trouble free driving. After finally getting rid of the crappy run flats, i put on a complete set of ps2. Definately the right move, car felt much better to handle. My question is are the tires that soft that after 4000mi i hardly have any thread left on the rears?(fronts are fine) No i do not drag race the car, or dump the clutch and burn the rubber. Most of the driving is in Florida so i understand the heat off the asphalt is an issue...but geez, pretty expensive 4000 miles. When i had the ps 2 installed they were balanced, had an alignment, and nitrogen put in. Are there other options in tires as money doesnt come to me like it used to. thanks for any comments
