I bought my BMW 325i 2006 Saden back in 2007. It has 1000 miles on it when I bought it. Didn't change all 4 tires till after 60,000 miles. The reason I have to change the tires is because of uneven wear of the front and rear tires. The second time I have to change my tires is when I got back from my deployment. Replaced only the front tires, because of the uneven wear of the front right tire. The odometer read 116,000 miles. That almost another 60,000 miles on the front tires and now I think its time for the rear tires to be replaced ODOmeter 126,500 miles.
I can't believed I've put in over 60,000 miles on these type of tires. Even the shop where I took my car to get my tires change. John told me that most of his customers that drives the same car as I do only put in around 30,000 miles on their tires before they have to change tires.
Definitely I will buy this type tires again if I need it tomorrow. Even though my wife tells me the ride is to rough.
