Default tire circumference

Hey guys, first post, if it has been asked (i did look for it) please just point.

Looking to replace my tires on my 997.2 Turbo S convertible I realized the circumference is quite different between front and rear.

Does that not cause any issues with the 4WD?

Thx

Use the PAG recommended tires and rims for your car and all is well.

Thanks, I sure will! No doubt,

Just wondering how the Porsche engineers have dealt with this topics as for other 4WD cars and pickups this is always an issue.

Your car's AWD system is not a locked system front and rear. Both the viscous coupler they used to have or your multi-disk electro-magnetically controlled clutches manages the power apportionment and axle wheel speed differential.
