Audi A6 The mid-sized Audi A6 model offers more room to the driver and passengers over the A4 line.

Do I really need all 4 tries?

ARE YOU WRITING THIS ALL DOWN> LOOK AT WHAT YOU HAVE STARTED> Just look at it! OMG.
The Michelin Pilot OEMs that came with my 05 4.2 lasted 14,000 miles. By the time I get to 10,000 miles the tires are crying. I must be a frustrated race car driver

I'll forward your opinion onto Audi and Volvo since we own(ed) one of each. They need to know this stuff.

"Maybe this will help explain why he said this.--All-wheel drive vehicles are equipped with additional differentials and/or viscous couplings that are designed to allow momentary differences in wheel speeds when the vehicle turns a corner or temporarily spins a tire. However, if the differentials or viscous couplings are forced to operate 100% of the time because of mismatched tires, they will experience excessive heat and unwarranted wear until they fail.

As an example of different tire diameters resulting from tires worn to different tread depths, we'll compare two 225/45R17-sized tires, a new tire with its original tread depth of 10/32-inch and a second tire worn to 8/32-inch of remaining tread depth. The new 225/45R17-sized tire has a calculated diameter of 24.97", a circumference of 78.44" and will roll 835 times each mile. The same tire worn to 8/32-inch of remaining tread depth is calculated to be 1/8" shorter with a diameter of 24.84", have a circumference of 78.04" and will roll 839 times per mile. While the difference of 1/8" in overall diameter doesn't seem excessive, the resulting 4 revolutions per mile difference can place a continuous strain on the tires and vehicle's driveline. Obviously, the greater the difference in the tires' circumferences, the greater the resulting strain.

I forgot to mention that I pasted this from the Tirerack website, but good info anyway. This is the general theory about allwheel drive cars "

Agreed.. you could get the other two later. Wont hurt a thing.

there are a number of reasons why, with few exceptions, you don't replace a single tire. always in pairs.
The only real reason to replace in pairs is to have the same traction across the diff...

10K and need new ones? What are you running, Mickey T's?

I find alot of this on this forum...

just to clear the air, when you were quoting me, were you trying to disqualify my statements? because for the most part, i can't see how the points you were making were different from the points i was making. the part i do see a difference in is the opinion that one wheel constantly turning a different speed than the wheel opposed to it will cause no damage. since jeffla already stated when i would have said, i'll leave it at that. to add to it, i have seen people use different brands as their basis for disqualifying tread depth recommendations. i, for one, would NEVER run different brands, models or tread patterns or even tread wear side-to-side. anyone who will is betting that they will NEVER have to rely on a balance of friction (heavy braking, for instance) to keep control of their vehicle.

Ya know, your right... I somehow missed the last part of the statement: "there are a number of reasons why, with few exceptions, you don't replace a single tire. always in pairs. most of them have nothing to do with diameter or drivetrain problems." I agree. My apologies

Agreed, and was my point, brief though that it was....


My apologies again...
