Normal for more tire wear in front?

The origin of NOT cross rotating tires goes back to the days of the Firestone 500 - the late 1970's, when steel belted radial tires were first introduced. There was a rubber chemistry problem. The chemical that was used to promote adhesion (HMT - hexamethylenetetramine) of the rubber to the copper in the brass coated steel wires, caused an acid in the presence of water, which corroded the steel. Water vapor can penetrate through rubber, so figuring this out was difficult, and Firestone was the last to do so - and they were stubborn about admitting they had a problem.

One of the things that was discovered during investigations was that the first detachments of the steel wire from the rubber occurred on one side of the wire - and to slow down the spread of these separations into a more generalized separation, it was recommended that steel belted tires NOT be cross rotated. I was not a fan of this approach.

Once all the tire manufacturers figured out the chemistry and changed it, the problem disappeared and there wasn't any need to recommend against cross rotating tires.

HOWEVER, these kind of things linger on - and even though it's been over 50 years, the recommendation is still remembered. If you'll notice, the USTMA (US Tire Manufacturers Association) says NOTHING about not cross rotating tires.

I still rotate same side front to back and have always surpassed the expected life of the tire by many many miles....

Macan is actively splitting torque and displays the status. Front and Rears are different sizes (apparently to reduce oversteer) so rotating doesn't happen.

And then there’s me who never rotates his tires and always exceeds the life expectancy. I just got 66,000 miles out of the original Michelin Super Sport back tires in my Corvette and 63,000 miles out of the last set of all weather tires on my Civic (and honestly those tires could have gone a lot longer but winter was coming and I wanted better tires)

Just make sure you tell the shop you want the -

Driver side front on the passenger side rear
Passenger side front on the driver side rear
Both rear tires stay on the side they are on they just go straight to the front.

Otherwise they will just swap front and rear on the same side -

But of course some tires can only roll one way - so you don't have this choice.

I had a new vehicle came with free oil changes and tire rotations - I told them how I wanted them rotated and they told me they would have to charge me if they did anything other than switching front to back - back to front on the same side.

I just said fine - I will never buy another vehicle from this dealership - they rotated them the way I wanted.
