Tire size C4S
 

I am putting Turbo II Factory 19" wheels and tires from a 997 on my 2002 996 C4S.

Front is 235/35/19 ( 25.5 inches high)and rear is 305/30/19 (26.2 inches high) ..am I ok on the 2.7% % difference ( 26.2 divided by 25.5) of front and rear for my all wheel drive ?

Thanks

Anyone ?

And if you have done this ....pic?

I did it with 245 in front no problem

The tranny can take a 10% difference with no problem thanks to the visco coupler.
We've done that for off-road application on a prototype that was based on a C4.

It would probably be an issue for older multidisc based 964 C4 systems but not for the visco used on the 996.
